Rendering

[Waspsarewankers]

We bought a house with an extension on the side that no one made the slightest bit of effort to blend in with the existing house. Different colour bricks etc. It looks shit an bugs me.

The front of the house blends in but in the back it looks horrendous and mismatched. Our garden is north facing but gets all day Sun 3/4 of the way down. This means my seating area is at the bottom of my smallish fully decked garden looking back at my mismatched house and extension.

I'm very tempted yo get the back fully rendered and painted ivory/cream to match my garden walls.

I've no idea though of how much or what work is involved in rendering. Do they just stick a coating on the bricks or do they do something to the bricks first? I'm guessing scaffold will be needed? How do they stick the tender on? Will my decking and York stone patio get wrecked?

Can anyone just explain the process and how messy it gets please?

Depends what sort of finish you want but either one or two coats of render (which is sand and cement unless it has little pebbles/gravel in it). Can probably use 'tower' scaffolding, depending on height. This is quick and easy to set up. Putting a diluted PVA glue on the wall first is used to make the new render 'stick'.
Mess? Not if they are decent renderers, or at least put suitable covering on the ground and clear up afterwards.
