EverbuildDeep Gap Filler – Ready Mixed – Easy To Use – Non-Shrink – Quick Drying – Overpaintable – Light Grey – 1 Litre

Now I am by no means a skilled tradesman, so there is certainly the chance someone with more experience or knowledge will be able to do better than me, but so far using this across various sized holes and materials, other than pretty shallow grooves, It has always taken longer than stated to dry, especially when filling a very large hole (i just leave it overnight). It has also always needed to be sanded down, no matter how hard I try to get a nice finish with a filler application tool/knife (I have tried a few types). I also have the best results when building up rather than trying to slap loads of the stuff in straight away... 50mm is pretty deep!With that out the way, everything else about this filler is top notch. It really is crack resistant and very easy to sand down to a perfect finish.It's pretty versatile and works great at patching up wallplug holes (including the big ones you get from cavity style plugs), filling around plasterboard repairs, patching up around backbones, light switches, and even though it says not to use it for screwing in, I have used it to help patch up holes that ended up being a little too big and it held up great, even with reasonable weight on it.It really shined when I needed to clean up the hole around the conduit (pictured before I have finished sanding) I recently installed for putting in CAT6/OS2 in my home. The wall wasn't particularly smooth to begin with but after using this stuff it has come out better than expected.I keep this stuff around as an all purpose filler, and I would highly recommend despite not quite meeting it's stated claims (in my experience).

Perfect for filling in big gaps and the grey is great as my floor is same colour. Filled in the holes 23 hours ago and just starting to harden. Possibly if it is just small gaps it will harden quicker but not for deep ones. Good at spreading etc.

This review applies to my first purchase. Gets a little messy, but this is phenomenal stuff. Its like concrete in a tub! Dries quite quickly and dries rock solid. Very easy to use but extremely tricky to manipulate for a smooth surface. Pretty pricey but well worth it. There are so many possible applications Highly recommend. Easy 5 stars.For my second purchase, image attached. That is a 1 star.

Brilliant for deep gaps ,you can sand and paint it . Great product good price .

This fills deep holes, but it took more than 24 hours to cure on some parts, the instructions to mix were weird, since it already appeared mixed, so maybe I didn't do a good enough job of it. Unlike the other filler I used, this one did shrink and I needed to apply a second coat. It was smooth but not perfect.

This product is very good i had quite a big hole on my wall,but no more this filler has been great in filling it and it is so easy to used ,however it took 24 hour to dry but when it doe's it dries like concrete well pleased with this product

Good product, have used it before, good size..works well BUT needs to sort out packaging there was no FRAGILE TAPE on..was nothing to hold in place... so has been knocked around loose.. lid was open and some filler leaked.. luckily was able to put it back in, ok.. taped it up and covered it.Hope it will still be viable when I use it otherwise waste of money.PLEASE SORT OUT PACKAGING otherwise great.

Good filler I’m happy with it
