Our fireplace was a perfect fit when it was installed, but now unsightly cracks have appeared around the edges. What you need is a sealant that's easy to apply - so you get a nice neat finish - and flexible enough to accommodate the stresses that lead to cracking, Polycell Squeeze & Seal Interior will solve the problem.

Step by step process
Rake out any loose filler or old plaster from the gap between the fire surround and the wall, and smooth away any old filler edges.
Polycell Squeeze & Seal comes in a special malleable pack that you simply squeeze to apply the right amount of sealant - no more struggling with wasteful cartridge guns! Cut the nozzle of the pack at a 45° angle to make a suitable width seal, then run a continuous bead along to fill the gap.
Smooth off neatly with a round ended stick or similar and wipe away any excess with a damp cloth before it dries. And there you have it - visitors' eyes will be drawn to your fireplace rather than the cracks around it!
