Features and Construction

This waterproof coating is engineered for easy application and effective sealing. It combines a liquid formulation with practical tools to simplify the repair process.

Material and Build

The coating formulation includes acrylic polymer emulsion as the main binder, which creates a waterproof film. Heavy calcium carbonate adds bulk and opacity. Dipropylene glycol monobutyl ether assists film formation, while alkali swelling thickener controls viscosity. 1,2-hexanediol acts as a preservative.

Size and Practical Fit

The 300ml capacity is designed for point repairs on leaks, cracks, and small areas. The tube allows easy handling, and the included needle tube provides precision for filling narrow gaps. The brush helps spread the coating evenly over larger patches.

Uses and Placement

Event or Professional Use

Professional maintenance teams can use this coating for quick repairs on flat roofs, gutters, and masonry. The brush and needle tube allow controlled application to different joint profiles.
