WHITECOAT SP is an elastomeric resin based, single component, ready to use, super elastic water insulation material.
Preparation of Substrate
The application surface must be dry, sound, mainly smooth, clean and clear of materials which prevent bonding, such as oil, rust, paint, silicone, curing agents, detergents and paraffin wax. Surface defects and voids should be repaired with suitable REPAMERK repair mortars. Steel surfaces should be primed with suitable anti-corrosion material before application. WHITECOAT SP diluted to 25-30% or SPR 104 acrylic primer should be used as a primer on surfaces like eternit, foamed blocks, brick, tile, masonry, concrete and plaster.
WHITECOAT SP is applied on the substrate by brush, roller or spray as two or three layers. Brush application direction in each layer must be perpendicular to each other. Minimum 4 - 5 hours should be waited between the layers. This product is not suitable on its own for waterproofing against hydrostatic pressure. It is recommended to reinforce the vertical and horizontal joints of excessively cracked surfaces by using geotextile protection layer or fibermesh.
0,75 kg/m² per layer for vertical, 1,0 - 1,5 kg/m² per layer for horizontal places. Recommended at least 2 layers application.
20 kg plastic bucket
