H20 Liquid Mask – 5L

Description

Walther Strong H2O Prime & Mask is a versatile, dual-purpose coating that works as both a primer and a peelable protective mask once dry.

Designed for a professional finish on windows, doors, and other surfaces, it eliminates the need for traditional masking or time-consuming cutting in – helping you save time and reduce labour costs on large-scale projects. Simply spray, roll, or brush it on.

For the best results, apply generously (two coats are recommended) to create a thick, even layer. Once the job is complete, the coating peels away cleanly – no taping, scraping, or sticky residue.

H2O Prime & Mask is popular with professional painters and decorators, and regularly features across social media for its speed, ease, and quality of finish.

It can also be used as a primer over knots (when timber is properly sanded) and is suitable for exterior priming applications.
