What Are Washproof Plasters and How Do They Help?

 

Minor cuts, grazes, and small wounds are part of everyday life — whether you're cooking, gardening, or keeping up with an energetic child. Washproof plasters offer a simple, reliable way to protect those wounds from water, dirt, and bacteria while they heal. Numark Washproof Plasters come in a pack of 24, making them a practical addition to any home first aid kit, handbag, or workplace medicine cabinet. At just £2.95, they're an affordable way to stay prepared. You can browse our full range of first aid products at Cured Pharmacy for everything you need to manage minor injuries at home.

Each plaster features a skin-tone, flexible backing that moves with your body, and a central absorbent pad that sits directly over the wound. The adhesive edges grip firmly to dry skin, creating a barrier that helps keep the wound clean during everyday activities like handwashing and light household tasks.

 

How Do Numark Washproof Plasters Work?

 

These plasters work through a straightforward physical mechanism rather than any active pharmaceutical ingredient. The absorbent wound pad draws away any minor exudate (fluid) from the wound surface, helping to keep the area clean and moist enough to support natural healing. The waterproof outer layer then acts as a physical barrier against water and environmental contaminants.

  • The adhesive border bonds to surrounding dry skin, holding the dressing securely in place.
  • The central non-adherent pad sits over the wound without sticking to delicate healing tissue.
  • The flexible backing conforms to curved body areas such as fingers and knuckles.
  • The washproof coating resists water penetration during routine activities, reducing the risk of wound contamination.

It's worth noting that these plasters are a medical device, not a medicine — they don't contain any active ingredients. Their protective function is entirely mechanical.

 

Who Should Use Numark Washproof Plasters?

 

These plasters are suitable for most adults and children dealing with minor, superficial wounds. They're particularly useful if you work in environments where your hands are frequently exposed to water — food preparation, healthcare, or cleaning, for example. That said, they're not appropriate for every wound type, so it's worth knowing when to use them and when to seek further help.

  • Adults and children with minor cuts, grazes, or small lacerations
  • People who need to keep a wound covered during handwashing or light activity
  • Those looking for an everyday plaster for the home, workplace, or travel first aid kit
  • Anyone needing to protect a small blister from friction and contamination

They are not suitable for deep or heavily bleeding wounds, infected wounds, or injuries covering a large surface area. If a wound shows signs of infection — increasing redness, warmth, swelling, or discharge — seek advice from your GP or pharmacist promptly.

 

How Do Numark Washproof Plasters Compare to Fabric Plasters?

 

Feature Numark Washproof Plasters Standard Fabric Plasters
Water resistance Yes — resists splashing and handwashing Limited — absorbs water readily
Flexibility Good — moves with skin Very good — fabric conforms closely
Breathability Moderate Higher — fabric allows more airflow
Best for Wet environments, frequent handwashing Dry environments, sensitive skin

 

Are Numark Washproof Plasters Suitable for Sensitive Skin?

 

Most people tolerate standard adhesive plasters without any issues. However, if you have a known sensitivity to adhesives or latex, it's worth checking the product packaging carefully before use. Some individuals develop contact dermatitis — a localised skin reaction — around the adhesive border of plasters. If this happens to you, remove the plaster and speak to your pharmacist, who can suggest a hypoallergenic alternative. If you're managing a wound alongside a skin condition, our skin care range includes products that may help support skin recovery around the wound site.

Store Numark Washproof Plasters in a cool, dry place below 25°C, away from direct sunlight and out of reach of young children. Check the expiry date on the packaging before use — adhesive quality can deteriorate over time.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Numark Washproof Plasters (24)

 

What Are Numark Washproof Plasters and What Are They Used For?

 

Numark Washproof Plasters are sterile, adhesive wound dressings designed to cover and protect minor cuts, grazes, and small blisters. They are classified as a medical device rather than a medicine, meaning they work purely by physical action — creating a protective barrier over the wound rather than delivering any active pharmaceutical ingredient. The NHS advises that minor wounds should be covered with a clean dressing to reduce the risk of infection and support healing. These plasters are intended for superficial wounds only and are not a substitute for professional medical treatment of deeper or more serious injuries.

 

What Do You Need to Know Before Using Numark Washproof Plasters?

 

Before applying any adhesive plaster, it's important to assess the wound and consider whether a plaster is the right choice. Do not use these plasters in the following situations:

  • On deep, gaping, or heavily bleeding wounds — these require medical attention
  • On infected wounds showing signs of pus, increasing redness, or significant swelling
  • On wounds covering a large surface area
  • If you have a known allergy to adhesive plasters or any component of the dressing
  • On the face of infants or very young children without medical guidance

There are no known drug interactions associated with adhesive plasters, as they contain no active pharmaceutical ingredients. However, if you are using a topical cream or ointment on or near the wound, allow it to absorb fully before applying the plaster, as residue can reduce adhesion.

  • No known drug interactions
  • Avoid use over topical medications unless directed by a healthcare professional

 

How Should You Use Numark Washproof Plasters?

 

Correct application makes a real difference to how well a plaster stays in place and how effectively it protects the wound. Follow these steps each time you apply one:

  1. Wash your hands thoroughly with soap and water before touching the wound or the plaster.
  2. Clean the wound gently under cool running water to remove any dirt or debris. Pat dry with a clean cloth or sterile gauze.
  3. Open the plaster packaging without touching the central absorbent pad.
  4. Peel back the protective paper strips from both sides of the plaster.
  5. Centre the absorbent pad directly over the wound without stretching the plaster.
  6. Press the adhesive edges firmly onto dry, clean skin, smoothing out any air bubbles.
  7. Check the plaster regularly and replace it if it becomes wet, dirty, or loose.
Indication Age Group Application Frequency
Minor cut or graze Adults and children One plaster per wound Change at least daily or when soiled
Small blister protection Adults and children One plaster over intact blister Change when loose or wet

 

What Are the Possible Side Effects of Numark Washproof Plasters?

 

Because these plasters contain no active ingredients, side effects are uncommon and are generally related to the adhesive or the occlusive nature of the dressing. Most people use washproof plasters without any problems at all. If you do notice a reaction, it's usually mild and resolves quickly after removing the plaster. You can find additional wound care and creams and ointments in our pharmacy range if you need to treat skin irritation around the wound site.

Common side effects:

  • Mild redness or skin irritation at the adhesive border when the plaster is removed
  • Slight discomfort on removal, particularly over hairy skin
  • Skin maceration (softening and whitening) if the plaster is left on too long

Less common side effects:

  • Contact dermatitis — a localised allergic or irritant skin reaction to the adhesive
  • Itching or a raised rash around the plaster edges

If you develop a significant skin reaction, remove the plaster immediately and seek advice from your pharmacist or GP. Serious allergic reactions to standard adhesive plasters are rare but possible.

 

How Should You Store Numark Washproof Plasters?

 

Proper storage keeps the plasters sterile and ensures the adhesive remains effective when you need it most. Follow these guidelines:

  • Store below 25°C in a cool, dry place
  • Keep away from direct sunlight and sources of heat
  • Store in the original packaging to maintain sterility
  • Keep out of the reach and sight of young children
  • Do not use after the expiry date printed on the packaging
  • Do not use a plaster if the individual wrapper has been damaged or opened

It's a good idea to check your first aid supplies regularly and replace any items that are out of date or have damaged packaging. A well-stocked, up-to-date first aid kit can make a real difference in an emergency.

Frequently Asked Questions

Where can I buy Numark Washproof Plasters online in the UK?

You can buy Numark Washproof Plasters (24) directly from Cured Pharmacy online for just £2.95. They are available without a prescription and can be ordered alongside other first aid essentials. Ordering online is quick, discreet, and convenient.

Are Numark Washproof Plasters actually waterproof?

Numark Washproof Plasters are designed to resist water during everyday activities such as handwashing, light cleaning, and brief splashing. They are not intended for prolonged submersion — for example, swimming or bathing — as extended water exposure can loosen the adhesive. For best results, pat the plaster dry after contact with water.

How do I apply a washproof plaster correctly step by step?

Start by washing your hands and cleaning the wound under cool running water, then pat it completely dry. Peel back the protective strips without touching the central pad, centre the pad over the wound, and press the adhesive edges firmly onto dry skin. Smooth out any air bubbles to ensure a secure seal.

How long can I leave a washproof plaster on?

You should change the plaster at least once a day, or sooner if it becomes wet, dirty, or starts to peel away. Leaving a plaster on for too long can cause the skin underneath to become soft and macerated, which may slow healing. The NHS recommends keeping minor wounds clean and covered until they have fully healed.

Can children use Numark Washproof Plasters?

Yes, washproof plasters are suitable for use on children for minor cuts and grazes. Adult supervision is recommended when applying plasters to young children to ensure correct placement and to prevent the child from removing and potentially swallowing the plaster. Always keep unused plasters out of reach of young children.

Who is eligible to use Numark Washproof Plasters?

These plasters are suitable for most adults and children with minor superficial wounds. They are not suitable for people with known adhesive allergies, those with infected wounds, or for use on deep or heavily bleeding injuries. If you are unsure whether a plaster is appropriate for your wound, speak to your pharmacist.

What should I do if my skin reacts to the plaster adhesive?

Remove the plaster immediately if you notice redness, itching, swelling, or a rash around the adhesive edges — this may indicate contact dermatitis. Wash the area gently with water and allow the skin to recover. Your pharmacist can recommend a hypoallergenic or silicone-based alternative if you have sensitive skin.

Can I use washproof plasters on blisters?

Yes, washproof plasters can be placed over intact blisters to protect them from friction and reduce the risk of the blister bursting. The NHS advises against deliberately bursting blisters, as this increases the risk of infection. If a blister is large, painful, or in an unusual location, seek advice from a healthcare professional.

What are the alternatives to Numark Washproof Plasters?

Alternatives include fabric plasters (more breathable, better for dry environments), hydrocolloid dressings (good for blisters and moist wound healing), and silicone-based dressings (suitable for sensitive or fragile skin). The right choice depends on the wound type, your skin sensitivity, and your activity level. Browse our skin care range for additional wound care options.

How do Numark Washproof Plasters compare to fabric plasters?

Washproof plasters offer better water resistance, making them ideal for people who frequently wash their hands or work in wet environments. Fabric plasters tend to be more breathable and flexible, which some people find more comfortable for longer wear. Neither type is universally better — it depends on your specific needs and environment.

What happens if I accidentally leave a plaster on too long?

If a plaster is left on for an extended period, the skin beneath can become macerated — appearing white, soft, and wrinkled — due to trapped moisture. This can slow wound healing and increase the risk of skin breakdown. Remove the plaster, allow the skin to air dry, and apply a fresh plaster once the surrounding skin has recovered.

Are Numark Washproof Plasters suitable for use on the face?

Washproof plasters can be used on the face for minor cuts, though the skin on the face is often more sensitive and the adhesive may cause irritation. Take extra care when removing plasters from facial skin to avoid damaging delicate tissue. If a facial wound is deep, near the eye, or shows signs of infection, seek medical advice promptly.

How should I store Numark Washproof Plasters?

Store the plasters in their original packaging in a cool, dry place below 25°C, away from direct sunlight and heat sources. Do not use any plaster whose individual wrapper has been damaged or opened, as sterility cannot be guaranteed. Check the expiry date on the pack regularly and replace when needed.

What are the latest guidelines on treating minor cuts and wounds at home?

Current NHS guidance recommends cleaning minor wounds under cool running water, applying gentle pressure to stop bleeding, and covering with a sterile dressing such as a washproof plaster. Antiseptic creams are not routinely recommended for clean minor wounds. Seek medical attention if the wound is deep, won't stop bleeding, or shows signs of infection within 24–48 hours.

How long can I keep using washproof plasters on a wound?

Continue using plasters until the wound has fully closed and is no longer at risk of contamination — this typically takes a few days for minor cuts and grazes. If a wound has not shown signs of healing within a week, or if it worsens at any point, consult your GP or pharmacist. For ongoing wound care needs, you may also find our pain relief range helpful if the wound is causing discomfort.

How Should You Use Numark Washproof Plasters?

Applying a plaster correctly is more important than it might seem. A poorly applied plaster can fall off quickly, allow contamination, or cause unnecessary skin irritation. Take a moment to prepare the wound and your hands before you start.

Follow these steps for correct application:

What Is the Correct Dose of Numark Washproof Plasters?

As a medical device rather than a medicine, there is no pharmaceutical dose for these plasters. The guidance below refers to appropriate use by wound type and age group. Use one plaster per wound, selecting a size that fully covers the injured area with the adhesive border resting on intact skin.

When Is the Best Time to Use Numark Washproof Plasters?

Apply a plaster as soon as possible after a minor wound occurs, once bleeding has been controlled and the wound has been cleaned and dried. Applying to a clean, dry wound gives the adhesive the best chance of bonding securely to the skin. Avoid applying immediately after washing your hands or showering, as residual moisture will reduce adhesion significantly.

If you need to reapply a plaster during the day — for example, after handwashing at work — make sure the skin is fully dry before placing the new plaster. Changing the plaster in the morning as part of your daily routine is a practical habit that helps keep the wound clean throughout the day.

How Long Can You Use Numark Washproof Plasters For?

Continue using plasters until the wound has fully closed and is no longer at risk of contamination or further injury. For most minor cuts and grazes, this takes between three and seven days. Change the plaster at least once daily throughout this period, or more frequently if it becomes wet, dirty, or loose.

If the wound has not shown clear signs of healing within seven days, or if you notice increasing redness, swelling, warmth, or discharge at any point, stop self-treating and seek advice from your GP or pharmacist. Deep wounds, wounds that won't stop bleeding, or injuries caused by animal bites always require professional medical assessment rather than home plaster treatment.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Numark Washproof Plasters?

Because these plasters contain no active pharmaceutical ingredients, side effects are uncommon and are almost always related to the adhesive or the occlusive nature of the dressing. The vast majority of people use washproof plasters without experiencing any problems at all. When reactions do occur, they are typically mild and resolve quickly once the plaster is removed.

  • Mild redness or skin irritation at the adhesive border after removal
  • Slight discomfort or pain when removing the plaster, particularly over hairy skin
  • Skin maceration — the skin beneath the plaster appearing white, soft, or wrinkled if the plaster is left on too long

What Are the Less Common Side Effects of Numark Washproof Plasters?

A small number of people may experience a more pronounced reaction to the adhesive used in standard plasters. This is more likely if you have a history of sensitive skin, eczema, or previous reactions to adhesive products. These reactions are not dangerous in most cases but can be uncomfortable.

  • Contact dermatitis — a localised inflammatory skin reaction causing redness, itching, and sometimes a raised rash around the plaster edges
  • Persistent itching beneath or around the plaster
  • Small blisters forming at the adhesive border in cases of allergic contact dermatitis

What Are the Serious Side Effects of Numark Washproof Plasters?

Serious reactions to standard adhesive plasters are rare. However, in very uncommon cases, a severe allergic reaction (anaphylaxis) can occur, particularly in individuals with a known latex allergy if the product contains latex components. Symptoms of a serious allergic reaction include widespread hives, swelling of the face or throat, difficulty breathing, or dizziness. This requires immediate emergency medical attention — call 999 or go to your nearest A&E department without delay.

If you have a known latex allergy, always check the product packaging carefully before use and speak to your pharmacist about latex-free alternatives.

What Should You Do If You Experience Side Effects?

For mild skin irritation or redness after plaster removal, simply remove the plaster, wash the area gently with water, and allow the skin to recover before applying a new dressing. If you develop a rash or signs of contact dermatitis, remove the plaster and avoid reapplying the same product. Your pharmacist can recommend a hypoallergenic or silicone-based alternative that is less likely to cause a reaction. Keep the wound covered with a non-adhesive dressing in the meantime if needed.

For any sign of wound infection — increasing pain, warmth, swelling, redness spreading beyond the wound edges, or discharge — stop using the plaster and seek advice from your GP or pharmacist promptly. A plaster alone cannot treat an infected wound.

Can Numark Washproof Plasters Interact With Other Medicines?

As a medical device with no active pharmaceutical ingredients, Numark Washproof Plasters have no known drug interactions. However, if you are applying a topical cream, antibiotic ointment, or other skin preparation to the wound area, allow it to absorb fully before applying the plaster. Applying a plaster over a wet topical product can reduce adhesion and may affect how the product works on the skin. If you are using prescription topical treatments on or near the wound, speak to your pharmacist for specific guidance.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
