Good product

Laid this levelling solution myself to get a level surface on a patio area - worked well You just need to get it down quickly and have a spiked roller to spread it

Good leveller

Used this to level a floor area 4x1.5 metres. Used 3 bags and found this product easy to use. Easy to mix with a good drill and paddle. Levelled off very well. Spot on. 👍🏻

good product

does what is say on packaging, easy to use, mixing took us bit longer and dry in recent dump weather took 4-5 hours, but humidity was 100%

Good.

First time using self leveling compound to prep sloping floor before tiling. 1200 x 1200 mm porch floor with 10 mm difference in height between one end and the other. I lifted the old tiles, scraped the floor, hoovered and primed it with Primeplus bonding agent. Mixed the compound as per instructions, although I only had a 12 L and 10 L buckets which are too small for one bag of this mix, yep, I should've thought of it, so I ended up dividing the mix. I poured it down, spread it, ran a spiked roller through it and it turned out OK, smooth and solid. P. S. Get yourself large sturdy mixing bucket. I'd say 20 L should do. Check the product manufacture dates before buying. Also, if there's a problem with the mix maybe you should send the batch number to the manufacturer as there could've been a problem on a production line?

First time using it. Worked great..

Never used any floor leveller before and chose this one as it was a good price and it had a higher maximum thickness compared to the others. Our fireplace was very uneven and sloped a lot. I wedged a piece of wood to the front and sealed the gaps with sealant. I used the full bag to make sure I got the mix right and used a drill paddle to mix it. It mixed well. Was pretty heavy to lift and pour it but went down well. After a few tense moments waiting for leaks it flowed well. Didn't have a spiked roller but just used a fork to poke out any bubble for the first 10 minutes.. I left it overnight and knocked the wood off the day after and very happy with how it turned out... Seems a perfect finish now for laying some tiles on top. Would definitely use again.... 😁

Favourite self level I've used!

I love this levelling compound! Easy to mix, easy to spread, levels really well, minimal rubbing down if any sometimes, even mixed up way to wet it still sets well, mixed up thick holds shapes reasonably well, sets nice and quickly, reasonable price. What more can you want!
