Colours Altamira Classic C-shaped Polystyrene Coving (L)2m (W)100mm, Pack of 6

These have been cut with not a care in the world , they don't match or mitre in the corners what so ever, not one out of the four packs I brought matched at the 45 degree angles , I gave up in the end and cut the lengths myself. Do yourself a favour keep well away its quite shocking these are even on sale.

I bought this product to save some time cutting corners and it would appear the only corners that were cut were in the factory. None of the corners have been cut correctly and this will be going back to B&Q.

hated every minute of putting this up . had to shave bits off to get them to match up. last time I put coving up about 10 years ago the corners came in 1 piece instead of 2 which was much easier to put up.

Where to start? The corners aren’t mitred properly so they’re less than 90 degrees, more like 80 and the edges have been chewed and torn by the blade. Trying to cut this tat cleanly is futile because it bends mid cut as the polystyrene grips the blade, which is probably the same problem they had in the factory mitring the corners accurately. Being polystyrene it also dents and marks ridiculously easily so you can’t fix it securely to mitre cut it without damaging the smooth finish. It’s such a poor quality product it ought to come with a free roll of Andrex. Buy yourself a bag of polystyrene beads and take them straight to the tip to save yourself the bother of trying to work with this stuff, unless you’re not bothered about having a decent finish and are a wizard with applying caulk that is.

I wish I had read the reviews before buying this kit. The pre mitred pieces are very badly cut. How is this product getting through quality control?
Luckily I have the tools to recut the corners.
