A finer version of our basecoat clay plaster for use over woodwool board or primed/gritted plasterboard where a smaller aggregate is advantageous for improved adhesion or thinner coats.
This basecoat does not contain fibre, add a mesh (such Jute mesh or render mesh) or a fibre (such as wood-fibre or fine chopped straw) or for the most robust basecoat use both.
