Waterproof Tanking vs Waterproof Plaster London

As a London homeowner, you know how unpredictable the weather can be. One moment the sun is shining, and the next, rain is pouring down, seeping into every crevice of your home. Picture this: you’re enjoying an evening at home, and suddenly, you notice damp patches creeping along your living room wall. The dilemma then arises — should you consider waterproof tanking or waterproof plaster to safeguard your property? In this blog post, we will delve deep into both solutions to help you make an informed decision.

Understanding Waterproof Tanking

Waterproof tanking is a method used to create a waterproof barrier on walls and floors to protect against moisture ingress. Particularly suitable for basements or areas prone to flooding, waterproof tanking solutions can be the perfect shield against the relentless London rain. Here are key points about tanking:

• Material & Technique: Tanking involves applying a thick coating, often made from cement-based materials, that creates a barrier against water.
• Application Areas: It is commonly used in basements, cellar conversions, and wet rooms.
• Cost: The average cost for waterproof tanking can range from £50 to £100 per square meter, depending on the extent of water damage and the area to be treated.

Pros of Waterproof Tanking

1. Effective Moisture Control: Ideal for spaces that face continuous dampness, such as basements.
2. Durability: Withstands external water pressure, ensuring long-term protection.
3. Fast Installation: Typically quicker to apply than plastering methods.

Cons of Waterproof Tanking

• Appearance: Tanking can be less aesthetically pleasing compared to well-finished plastered walls.
• Requires Ongoing Maintenance: If the tanking layer is damaged, it may require reapplication.

Understanding Waterproof Plaster

Waterproof plaster, on the other hand, is a blend of plaster and additives designed to repel water. It’s an excellent choice for areas that need moisture control but still require a polished finish. Here’s what to know about waterproof plaster:

• Material: It consists of gypsum or cement with additives that enhance water resistance.
• Ideal Spaces: Typically used on interior walls, especially those in kitchens and bathrooms.
• Cost: Waterproof plastering ranges from £35 to £80 per square meter, which can be more cost-effective for extensive areas.

Pros of Waterproof Plaster

1. Aesthetic Appeal: Smooth, attractive finish that is perfect for interior settings.
2. Less Risk of Cracks: The flexibility of plaster allows for minor movements in the structure without cracking.
3. Versatility: Can be applied in various environments, ideal for custom designs.

Cons of Waterproof Plaster

• Less Effective Against Flooding: Not as effective as tanking in heavy water pressure situations, such as flooding.
• Longer Application Time: The drying and application process can take longer.

Key Differences Between Waterproof Tanking and Waterproof Plaster

When deciding between waterproof tanking and waterproof plaster, consider the following differences:

• Application Area: Tanking is better for external walls and high-risk damp areas. Plaster works well for internal walls where moisture needs managing but isn’t as extreme.
• Cost Efficiency: Tanking can be more expensive due to material costs, while plastering may provide a more economical solution for extensive wall applications.
• Longevity & Maintenance: Tanking systems may require more frequent checks compared to waterproof plaster, which, although requiring proper care, can offer a longer aesthetic lifespan if maintained properly.

Practical Tips for Applying Waterproof Solutions

Steps for Waterproof Tanking:

1. Prepare the Surface: Clean the walls thoroughly, removing any loose material or dampness.
2. Apply Primer: Use a suitable primer to improve adhesion.
3. Tanking Coat Application: Apply the waterproof tanking material in two coats using a trowel or roller.
4. Seal the Edges: Pay attention to corners and junctions, sealing them well.
5. Allow to Cure: Let it cure as per manufacturer instructions before rendering or plastering.

Steps for Waterproof Plastering:

1. Surface Preparation: Ensure walls are clean, dry, and dust-free.
2. Apply a Base Coat: Consider a bonding agent if needed.
3. Mix the Waterproof Plaster: Follow the manufacturer’s instructions precisely.
4. Plastering: Apply using the trowel, starting at the bottom and working upwards.
5. Finishing Touches: Smooth out for an even finish, then allow it to dry completely before painting.
