The Evercryl by Sika is one of the sought-after products on the market. It delivers one of the best waterproofing coats available, instantly activating as soon as it's applied to the surface.
Evercryl uses fibres inside its formula, offering bridge-filling properties that repair slight tears in roofing felt and hairline cracks in gutters. All of this is achieved in just one coat, which allows quick application and gives confidence that it's sealed and waterproof. Surfaces that this roof coat can be applied onto include;
- Concrete
- Fibre/cement
- Roofing felt
- Mastic Asphalt
- Bituminous roof coatings
- Rigid PVCu corrugated iron
- Metal
- Slate
- Brickwork
- Tiles
- Lead
- Copper
- Zinc
- Plastic Gutters
- Metal Gutters
Preparation
Before commencing the application, you must check the surface. You must remove contaminants on the surface, including impurities such as dirt, dust, grease, organic growth and debris.
Use a stiff-bristled brush to remove dirt, dust, debris and other surface contaminants. Treat any moss, algae or organic growth with a suitable cleaner before application.
Treat any rusted areas with a rust-inhibiting primer to prevent further corrosion. Prime all non-bituminous, porous or friable surfaces before application to ensure strong adhesion.
Replace any severely damaged tiles, slates, sheets or other roofing materials before starting the repair. While Sika Evercryl can seal small cracks and minor surface defects, it cannot repair broken tiles or extensively damaged roofing components.
Application
- Stir thoroughly before using, ensuring all the pigment is mixed
- Using a brush, apply one coat at a rate of 1-2 litres per square metre
- In certain cases, you may need a second coat, which should be applied 2-3 days after the initial coat.
Limitations
- This product should not be applied in areas where subsequent solvent or oil contact is likely.
- Avoid inhaling any of the vapours
- Do not apply to Styrofoam or PVC foil
