A concrete soffit is the underneath section of a balcony, arch or overhanging eave.
Before you begin
You will need:
Scaffolding trestle platform
Club hammer
Cold chisel
Scutch chisel or hammer
Scutch comb or drove
Block brush
Scutch chisel or hammer?
The choice of whether you use a scutch chisel or scutch hammer is down to the number of small lumps and bumps in the surface of the soffit. A scutch hammer can remove more material at a greater rate so would be more suited to a soffit with a large amount of lumps and bumps.
Prepare a soffit
Step 1 – Remove material from soffit
Use a club hammer and a cold chisel to remove any large pieces of material sticking out of the soffit.
A soffit is made of either wood or concrete depending on the materials the house is made from.
Next, use a scutching tool (either a scutch chisel or scutch hammer) to knock off any remaining small lumps and bumps from the surface of the soffit.
Step 2 – Sweep soffit
Use a block brush to sweep the soffit clean.
Next, use a splatter dash to create a rough surface for the plaster.
