Next, fit a Polycell Sealant Exterior cartridge into a skeleton gun and slice the nozzle at a 45 degree angle to produce a thick enough bead to seal the gap. Now, squeeze the gun trigger to start the flow and, pushing the gun nozzle forward, run a continuous bead along the length of the gap.

Finish off with a round-ended stick or similar tool and wipe away any excess with a damp cloth before it dries, normally in about six hours.
