We have specially developed our Prep Coat as a bridge coat between standard paint and primers to make limewash more durable, and easy to apply. Bauwerk Prep Coat is not a primer. It is important to understand that Bauwerk Limewash and Prep Coat have no capacity to mask what is on your wall, it allows all the history and the materials of the wall to come through.
Natural walls, such as unpainted render, brick, stone, masonry, mud brick & limewash.
Do not require any undercoat or primer. Limewash can be applied directly to the wall.
Previously painted render, brick, stone, masonry, mud brick.
Carry out any surface repair and remove all dust and loose particles. No undercoat is required. Sand well if previous paint has any gloss level. Previously painted masonry internal walls with inconsistent wall finish or gloss finish–you can apply 1 coat of Bauwerk Prep Coat to create a more uniform finish.
