Before we quote in Carmarthen
Surveys in Carmarthen also cover the surrounding SA31 district and towns such as Llanelli and Ammanford. Carmarthen is about 14 miles from Llanelli. West Wales has a high share of older solid-walled and stone homes, many in exposed coastal or rural settings.
Parts of Dyfed 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.
Extensions and new blockwork in Carmarthen are where monocouche makes most sense.

Approvals in Wales
For homes in Carmarthen, the local planning authority decides any borderline cases; changing a brick house to render, or work on flats, usually needs an application in Wales.
Welsh Building Regulations expect walls to be upgraded when a substantial area is renewed, and building control signs the work off.
Why does monocouche sometimes look patchy?
Colour variation (often called shading) can appear if it's applied in poor weather, on walls with uneven suction, or in sections on different days. Working an elevation in one go in suitable conditions keeps the colour even.

Monocouche render in Carmarthen: questions
Monocouche or silicone for an extension?
Both work on new blockwork. Silicone over a base coat costs a little more but tends to stay cleaner.
How long does monocouche last?
Typically 20 years or more on a suitable wall, depending on exposure and detailing.
Is monocouche waterproof?
It's water-resistant and sheds rain, while still allowing some vapour through.
