This Victorian build had failed cement render on. Cement renders on lime mortar builds are a recipe for disaster. As it traps moisture, trapping air that is trying to escape. Cement acts as a strong barrier and is not suitable on older homes
First port of call was to sheet up. Sheeting up doors, windows and the floor.
Next we needed to knock off the failed cement render. We did this using breakers trying our best to get behind the render. We were able to keep the original brickwork in an ok state ready for the rendering to begin.
A slurry coat was applied next. We did this using a spray hopper gun connected to a compressor. By doing this we achieved a strong stipple. Making it an excellent key for the next coat. The product used for this was fassa s650.
Next was putting on beads. The beads used were 10mm in thickness. We plumbed them up level with our laser level and spirit levels.
Now we were ready for the lime basecoat. We sprayed the render on using our render machine . The machine sprays at the right thickness and consistency making life a lot easier. The machine used is pft ritmo l. Once the render was sprayed and the machine was cleaned. We ruled the render flat with serrated edges. This gave it the correct key to sink in the reinforced mesh. We then closed in the mesh and flattened off ready for the next coat. The material used was fassa KB13.
The last coat is a skim coat. This is put on a lot tighter skimmed on in two passes. Keeping it as flat as possible. This is applied with the hawk and trowel. We then hit the wall top to bottom with a power-float . Lastly we gave it a hand sponge to achieve a uniform flat finish. The product used was fassa s605.
We also supplied the correct breathable paint. After the render cured it could be applied.
