Rhondda: walls, weather and approvals
We cover Rhondda and nearby Aberdare, Pontypridd and Merthyr Tydfil. South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Parts of Mid Glamorgan fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
On tree-shaded or north-facing walls in Rhondda, silicone's water repellence helps it stay cleaner for longer.

Approvals in Wales
Householder rules in Wales are similar to England's: in Rhondda, a similar-looking finish on a house is often permitted, but conservation areas, flats and listed buildings need permission or consent.
In Wales, insulating or re-rendering more than half of a wall's area is treated as renovating a thermal element under Approved Document L (Wales), so building control is involved before work starts.
Silicone or monocouche?
Monocouche is a thicker single-coat cement render used mainly on new blockwork. Silicone is thinner, more flexible and usually more resistant to staining, and it's the finish used over insulation. On older or mixed walls, silicone over a mesh-reinforced base coat is generally the safer choice.

Silicone render in Rhondda: questions
Can I paint silicone render later?
Yes, with a compatible silicone paint, though through-coloured render rarely needs it.
Can silicone render go over old render?
If the old render is sound and well bonded, often yes after cleaning and priming. Hollow or cracked areas are cut out and repaired first.
How long does silicone render take to dry?
It's touch-dry within hours but needs dry weather above about 5°C for the first day or two to cure properly.
