Patching Compounds

Adequate surface preparation is critical to ensuring the long-term performance of any ROCKCOTE system.

ROCKCOTE’s patching and jointing compounds assist professionals to prepare just about any substrate for coating.

ROCKCOTE’s patches are easy to use, tough and suitable for interior and exterior use.

Patch & Prep: a pre-blended polymer-modified cement base coat that requires the addition of cool, clean water and mixing before application. Used primarily as a jointing compound on fibre cement sheet. Also used to patch and repair concrete on walls and ceilings prior to painting or refurbishing.

Hard Patch: an acrylic, water-borne compound designed for patching holes, form joints and imperfections in concrete or masonry walls. Requires the addition of cement.

Smooth Sanding Patch: a pre-blended, ultra-fine, water-based acrylic patching compound. Ideal for patching pre-cast concrete panels prior to coating. For external applications, the addition of cement is required.

Keycote: a pre-blended polymer-modified cement base coat used primarily where adhesion to difficult substrates is critical. Ideal as a base coat for smooth, dense masonry or for rendering over a previously painted wall.

Smooth Set: Designed for patching holes, form joints and minor imperfections in concrete or masonry walls. Requires only the addition of clean water.

Fungicidal Wash

Moss, lichens and other commonly occurring fungi and algae can be detrimental to any coating system, whether it be present between the substrate and surface coating, or on the coating itself.

ROCKCOTE’s Fungicidal Wash acts as a residual fungicide when applied between the substrate and surface coating.

ROCKCOTE’s Fungicidal  Wash is a safe and effective water based treatment for killing moss, lichens and all commonly occuring fungi and algae.

A safe and effective water-based treatment, ROCKCOTE Fungicidal wash comes ready to use and is suitable for use on masonry, concrete, brickwork, stone, render, paintwork, roofing and most other building materials. Can also be used on roofing, guttering, downpipes and driveways.
