How To Fill Awkward Or Large Gaps Around Your Pipework Or Fixings

Step 1: Cover Surrounding Areas

Cover all surrounding areas before you start. Put on safety glasses and protective gloves.

Step 2: Clean

Ensure that the gap and wall around the pipework is clean and free from grease and loose material. Then mask off any cupboard or appliances close to the gap.

Step 3: Moisten Surfaces

Moisten the surfaces to help the foam cure and expand; a household plant sprayer filled with water is ideal.

Step 4: Shake Can

Remove the cap of the Polyfill Expanding Foam Polyfilla carefully and - holding the can away from your face - shake vigorously about 20 times to mix the contents. Then carefully screw on the supplied applicator nozzle.

Step 5: Apply

Hold the can of Expanding Foam upside-down and direct the applicator inside the hole, applying pressure as required. Shake the can from time to time during use. The foam will expand to 2-1/2 the amount you start with, so take care not to overfill.

Step 6: Foam

After 24 hours the foam can be cut, sanded, plastered or painted over.

Step 7: Interior Areas

For interior areas, finish the task by using Polycell One Fill Polyfilla.

Step 8: Smooth Finish

Remove the lid and stir into a smooth paste. Press the filler into the gap using a filling knife and smooth off with a wet knife. This lightweight filler leaves a perfectly smooth finish that should require no sanding.
