Which Resin is Best for Waterproofing Bathroom Walls or Kitchens?

← Back to Can I use resin for vertical applications?

If you need a resilient, moisture-resistant finish on your bathroom or kitchen walls, not just any paint or coating will do. Dedicated resins designed for interior vertical surfaces ensure reliable waterproofing and a stylish, cleanable finish.

Why Choose Resin for Bathroom and Kitchen Walls?

Bathrooms and kitchens experience frequent moisture and splashes, so protecting walls from water ingress is essential. Traditional paints and wallpapers can struggle with humidity and cleaning chemicals. Using a resin coating delivers a seamless, washable barrier that stands up to damp, ensuring surfaces stay looking fresh and are simple to maintain.

What Makes a Good Waterproofing Resin?

Look for a resin specifically formulated for use on vertical surfaces, such as Vertical Glass. This product is intentionally non self-levelling, so it won’t run or sag during application. It resists moisture and produces a glossy, easy-to-clean finish, ideal for showers, splashbacks, and sanitary areas. Its versatility means it can be tinted with pigments for unique decorative results, working on substrates like tile, cement, wood, or brick.

Application and Practical Tips

• Preparation: Ensure surfaces are dry, clean, and free of oils or dust. Good preparation aids adhesion and waterproof performance.
• Application: Apply resin with a spatula for full coverage. Thin applications provide a vitrified effect; thicker layers offer extra protection. The finish can be sanded once cured for a tailored sheen.
• Customisation: Pigments, including metallics, can be added for an individual look, matching your room’s style.

When This Matters

Resin wall coatings are ideal in environments where frequent cleaning, humidity, and splashing are the norm—particularly for bathrooms, shower enclosures, kitchen splashbacks, or utility areas subject to regular moisture.
