APPLICATION

Whilst the substrate is still damp but free from standing water, apply the first coat by brush, broom, roller or squeegee (if the surface is flat enough), working the material well into the substrate to achieve full bond.

Allow 4–8 hours (+20 °C) for the first coat to cure before applying the following coats in the same manner.

For large areas, SikaTop® Seal-109 MY can be applied by spray using a suitable worm type mixer/pump.

An additional stripe coat is recommended over cracks, wall/floor intersections, etc. as these locations are where movement is most likely to be expected in service.
