Hi,
We are building the house extension which faces the front line of the property. The main house is 60% and the extension will add 40% to the front area. Now our main house is bagged and painted in grey. I wonder what our options for the extension. Say,
1. Bag it and paint in the same colour as our builder suggested to match the house.
2. Properly render the extension front wall but leave the main house bagged.
3. Render the extension and render the main house over the bagged surface.
I am not sure whether in option 3 the render will stick to the bagged painted surface. I know it won't to the painted bricks but the bagged wall is quite rough. If not sure, I don't want to risk it. What could be the price difference between bagging and proper rendering ? Bagging is included into the contract and our builder is flexible and can upgrade it to rendering if asked.
