H20 Liquid Mask – 250ML

Description

Walther Strong H2O Liquid Mask & Primer is a simple, water based solution that primes timber and masks glass in one simple application. It is widely used by professional painters and decorators for its speed, reliability, and high quality finish.

H20 Liquid Mask is ideal for glazed timber doors, windows and frames, removing the need for traditional masking tape or time consuming cutting in. Once dry, H2O forms a flexible protective film that shields glass during painting, then peels away cleanly in when the job is complete.

The product can be sprayed, rolled, or brush applied, making it suitable for both large scale commercial projects and detailed domestic work. For best results, apply generously using two coats to build a thick, even layer that ensures easy removal and crisp paint lines.

In addition to masking, H2O can be used as a primer on bare timber, including over knots (when correctly sanded), and is suitable for interior and exterior applications. It is compatible with 2K paint systems and approved for use on Accoya® wood, making it a versatile choice for modern coating systems.
