Thompsons One Coat Water Seal

Thompson's One Coat Water Seal uses a unique micro silicone emulsion to stop water penetration. Apply just one coat of Water Seal directly onto damp surfaces to provide long lasting waterproof protection within hours.

Prep : Give the surface a decent scrub with a stiff bristle brush. Fill any cracks and do pointing repairs, if needed.

Application: Give the tin a good shake. Apply using a brush or roller. If you're tackling a wall, work in 1m sections from the bottom upwards. Once an area is fully saturated move onto the next section. Don't forget to give those mortar lines a soaking too. Make sure you treat the whole wall and not just isolated areas. It's just one coat, so that's it job done!

Cleaning: Clean your equipment in warm water and detergent.

Drying Time: 2 hours
Coverage: 4m2 per litre
