Homes and walls in Derry~Londonderry
We cover Derry~Londonderry and nearby Strabane, Limavady and Coleraine. Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Parts of County Londonderry 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.

Approvals in Northern Ireland
In Northern Ireland, permitted development is set by the 2015 Order; in Derry~Londonderry, changing a house's external appearance, and any work on flats or listed buildings, may need permission, so we check with the council.
Building control applies to insulation and major re-rendering in Northern Ireland, and the work is signed off by the council.
How is silicone render applied?
On masonry, the wall is prepared and any loose material removed. A base coat with glass-fibre mesh is applied over the whole wall to resist cracking, followed by a primer and the silicone finish, trowelled to its grain size. On EWI, the same base coat, primer and finish go over the insulation boards.

Silicone render in Derry~Londonderry: questions
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.
Does silicone render crack?
The mesh-reinforced base coat and the render's flexibility make cracking much less likely than with sand and cement, but structural movement in the wall can still show through.
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.
