NOBODY makes premoulded coving corners anymore! Last time I did coving, I had to use a mitre box and saw. This is a nightmare because each angle and cut has to be right or you bodge the coving. Mistakes mean you need more.

So I was happy to have these precut and give it a go. 8 corners in total. I sliced them straight, and sanded off the rough bits, but noticed how most of the two pieces seemed to be cut from different sized mouldings - there was some overhang of a few millimetres on them (see photo).

Then I tried to fit them into the corners… no wall is perfectly straight, yes, but these wouldn’t fit into ANY corner!! When you put them together and look at them from underneath, you see that EVERY piece is about 10 degrees off of 90!! (see photo) You WILL cut better corners yourself with a mitre box, no doubt.

Half a morning wasted and another trip to B&Q for a refund. I’m getting tired of the rubbish that this mega company are selling!

Do not buy

This product is not fit for purpose. The idea of these corners is to save on cutting but THEY ARE NOT 45 degrees. Unless your walls are way out, these are no good for you. We had to return this product and cut the straight coving ourselves. a mitre block and saw will do the trick!!

Not very good.

Having done coving before with preformed corners some years ago; I wanted to do same in a recent extension. The 100mm deep straight polystyrene had improved - very smooth surface; no poly bubbles to cover with paint! Disappointed the 2 pk internal/external corners; you can only use the 2 pieces to make 1 corner; cutting them in half; the other ends for external now wasted/not needed - expensive! They are not true 45 degree cut; had to shave edge One side to fit; the curve not quite matching the lengths so a lot of shaving/filling - my husband nearly made me give up and take back what we hadn’t used.

No two pieces the same

Bought these as working to a budget. No two pieces were the same with the manufactured cuts all being at different angles. Eventually managed to get them to fit (with a lot of filling, sanding and fettling). The straight lengths are great for the price but these were just more trouble than they were worth.

While using ordinary Coving for an Expert doing the corners with Straight pieces is probably easy but a for normal Diyer is or can be a expensive mistake to make. These Corner pieces come in 2 versions in a pack. Look good when up and finish the work nicely.
