The Water Seal by Sika is the ultimate surface water sealer with a solvent-based formula designed to protect against water, dampness, and frost. It penetrates up to 5mm deep into the surface, lining the pores with a water-repellent coating without causing significant changes to the surface. Unlike some on the market, this product doesn't restrict the breathing of the surface, instead caring for it and allowing the breathing property to flourish. The Water Seal can achieve up to 10 years of protection, depending on the surface it's applied onto, its absorbency, application rate and position.
The surface should be prepared before commencing the application. Complete this by removing all contaminants on the surface, such as dirt, dust, oil, grease, etc. Any defective joints in brick and stone work should be repointed; hairline cracks don't need to be treated, but it's suggested.
- Stir well before using
- Apply by brush or using a low-pressure spray in one coat
- The Water Seal should saturate the surface to obtain a rundown of approximately 300mm.
To clean any equipment or tools used during the application, use white spirit as soon as you've finished.
