Exterior finish
Stone Quartz Exterior Coatings in Bath
A decorative wall finish for suitable, correctly prepared exterior backgrounds.
The problem
A tired wall needs proper preparation
Cracks, hollow render, staining and water ingress can all show through or undermine a new exterior finish if the background is not dealt with properly.
We assess what is already on the wall and set out the preparation required before discussing the final texture and colour.

The right solution
Preparation first, then a consistent textured finish
Once the background is sound and suitable, the Stone Quartz system is applied to create a consistent decorative surface.
Colour, texture, access and maintenance guidance are discussed before work starts so the finish fits the property and the wall condition.
- Distinctive textured appearance
- Applied to assessed, prepared backgrounds
- Suitable colour and finish agreed first
- Careful work around openings and details
- Straightforward maintenance guidance
Where it fits
Properties and areas this can suit
- Sound rendered walls
- Selected masonry backgrounds
- Garden and boundary walls
- Residential exterior elevations
- Properties needing a decorative textured refresh
Honest advice
The cause still matters
This is an exterior coating, not a cure for structural movement or penetrating damp and not a substitute for a full insulation system. Any background defects must be addressed in the specification.

Questions homeowners ask
Common questions about stone quartz exterior coatings
What is a Stone Quartz exterior coating?+
It is a decorative textured exterior finish used on properly prepared wall backgrounds. The exact specification depends on the substrate and desired appearance.
Can it cover cracked or loose render?+
Defective areas must be investigated and repaired first. A finish coat should not be used to disguise unstable material or water ingress.
Can I choose the colour and texture?+
The available finish depends on the selected coating system. Samples should be agreed before application.
Is it an insulation system?+
We do not present a decorative Stone Quartz coating as a replacement for a thick external wall insulation build-up.
