Technical Information

CURE MECHANISM

The curing of Sikafloor® Marine-504 takes place by a chemical reaction of the two components.
Higher temperatures speed up and lower temperatures slow down the curing process.

Application

Application Information

Surface Preparation

Dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush or vacuum. Ensure that substrates are clean, dry and free from all contaminants such as dirt, oil, grease, coatings and other surface treatments.

Application

Prior to application confirm relative air humidity and dew point.

When starting to coat, make sure the coating rollers are well saturated with coating.

After proper mixing the product is poured and spread out on the floor in respect of the coat weight. Note: Keep an eye on the pot life since the end of the pot-life is not visible.

Roll with a larger 50 cm roller in one direction cross the working direction to eliminate lap-marks.
