Pre-Patch Coarse

Pre-Patch Coarse is a 100% acrylic, water reducible thin section render and patching compound that is supplied ready for use straight from the drum, apart from the required addition of cement for exterior use.


100% Acrylic Skim Coat.


The product can be applied by either hawk and trowel or mortar spray devices and is suitable for application to most correctly prepared mineral based construction surfaces such as flush jointed block work, HardiTex™, Hebel® and racked brick, including, well adhered “gloss free” painted surfaces.

The product is principally used to skim entire walls and to feather edge surface misalignments in concrete prior to the application of a medium profile texture.

Pre-Patch Coarse will cover surface misalignments of 2 to 4mm and will feather down to 0.65mm.
