Coloured exterior wall rendering

The coloured rendering system

All common building problems, and much more, can be quickly and easily cured with the application of a coat of coloured render, supplied and applied by experts, and it never needs painting. Companies offer a coloured monocouche rendering, which is a weatherproof, insulated, polymer-modified, coloured through render wall coating system for exterior walls, and is applied by skilled, factory trained technicians.

It can cure all exterior wall defects, it can stop penetrating damp, and it requires no maintenance or painting, for at least 25 years! It also helps insulate your home, saving you a lot of money in lower heating bills.

What is “through-coloured” render?

GRC coloured render is a high performance coloured render based exterior wall coating system, manufactured in the UK by Wetherby Stone Ltd. The colour is contained in a special pigment, which is mixed into the render, meaning that when it is applied to the outside of a building, the wall surface is a rich, uniform colour of your choosing that requires no painting at all ever again!

The rendering system is a highly polymer modified and fibre reinforced high performance cement based waterproofing base coat which has excellent workability and finishing time properties the ultimate base for mixed substrates. This product can be applied by hand or spray in low temperatures and used as a scratch base coat ready to receive a through coloured render or as a flat finish ready to receive a Thin Coat Render.

What does coloured render look like?

There is nothing more explanatory then showing you what this product looks like on someone else's house, rather than us show you some bags of cement! Far more interesting too. So we put together a few photos of a typical coloured rendering job, to show how we apply it and what it looks like when we have finished.

The example on this page shows a recently external render completed job in Ormskirk, Lancashire.

The coloured render we use is based on a mix of co-polymer resins, cement and glass fibre, meaning it is super tough and resists damp, whilst being moderately flexible and fully breathable. CRACK RESISTANT GRC render wall coating system is available in a variety of colours.

The coloured render system, once applied to the walls of a house, gives the external surface of the building a long lasting, damp proof, durable wall finish, with a never fade colour you can really stand back and admire for years to come, with zero maintenance!

How is the render applied?

The scratch coat (the first coat of render to be applied to the house), is a polymer base coat which is specially designed for painted surfaces and although it's not the cheapest product available, it is well suited to homeowners who do not want the hassle of maintenance at all.

The GRC render also has an added strength of incorporating a plastic mesh as a strengthening binder, and is "pushed" into the base coat to provide EVEN MORE strength and durability. Each job has custom made render which is suited to your home, including your desired colour and exterior wall finish, textured or smooth. The material can be mixed and matched with other products like clear coatings on stone.

This job had to have various repairs to the walls, although generally it had been maintained well and was in quite good condition. The house had a a coat of render applied which was then scratched out by the team to ensure a good key for the coloured render top coat to be applied.

It is important to have a weatherproof wall coating on an exterior wall as this is the surface around the house that has to withstand the harsh weather, wind driven rain, pollution and cold.

For architects, builders and all the techy bods out there, In installing this system via our dedicated rendering teams, we adhere to The Code of Practice for Renders BS 5262 1991 and NBS Building Specification section M20. It also helps in compliance with Section B2 of the Building Regulations & the obligations under the Regulatory Reform ( Fire Safety) order, known as (RRFSO).

....and in a world where most people now have to watch the pennies, but many companies offer a long guarantee on these rendered external wall surface finishes, you can be sure to save a LOT of money in the long run on future maintenance!
