Coverage table for CreteSafe , SealRoof  and MetalSafe

Before a spray application of the CreteSafe  membrane ensure the concrete surface is dry and free of any dirt or loose materials. Voids and joints larger with a width of 1/8" or more should be sealed using a brush coat of TrowelGrade over geo textile. All penetrations, right angles and corners need to be coated with TrowelGrade  prior to spraying with CreteSafe

Roof surfaces should be clean and dry. If ponding water is found, remove water and allow the area to dry 48 hours prior to application of SealRoof . Surfaces should be free of any loose materials, all cracks should be sealed with liquid brush-on rubber over geo textile prior to a spray application of SealRoof

For repair and restoration of BUR roofing ensure that all roofing granuals have been removed and the surface power swept. Check and repair flashings, curbs, parapets, drains, roof edges and roof penetrations prior to applying SealRoof . Do not apply SealRoof  over existing EPDM or coal tar surfaced roofs. On roof waterproof restoration projects it is recommended that a thermal scan be conducted to identify hidden moisture that can degrade the new membrane.

On new roof surfaces ensure that all construction materials and scrap have been removed and the surface is clean. Seal all joints with a coating of liquid brush-on rubber over geo textile, prior to the spray applied SealRoof  membrane.

For best results always keep the nozzle tips at right angles to the surface being sprayed. If there is a breeze, ensure that the part ‘B’ or accelerator side of the spray gun is facing the wind.

On vertical surfaces, start at the bottom and work up.
