                  quick setting!
                  Had about a 30 sq ft area to level slab on grade. From feathered edge to about 1/4” drop along the wall. Not easy to do! Works better if doing a whole area or room. Only myself, not easy to mix on your own. Also suggest using maximum amount of water would help with self leveling and work time.

                    Good product.
                    Good product, but bad instructions on the bag. 8 liters of water per bag is more like it.

                      A great product if you have 24 hours to cure
                      Read the reviews of many happy customers for specific instructions on this product, or just read the instructions on the back and follow them to the letter. The product is straightforward and does its job exactly as expected if the surface you are leveling is suitable for use with it and is properly prepped. The grumpy reviews should be ignored because they are due to incorrect usage.

                        Fairly Easy To Use
                        Absolutely a two person job to get good results for a large area. I used 22 bags in my basement, and with one person mixing and the other person pouring and guiding with a squeegee worked out well. The finished results ended up better than expected.

                        did not self level / no working time
                        I mixed it thin and it still dried in under 2 minutes and did not self level at all. not only is it a waste of 30$ but ruined the room and can't even try to grind down high spots without a house filling amount of dust

                          Self levelling my...
                          Did not self level. Not sure the floor is any more level than it was before. Also, applied over a plywood + chipboard + old vinyl floor, it cracks all over the place when it is walked on and the floor flexes. At this point I'm not sure it won't crumble.

                            Easy to work with it if you have gap make sure you use gap filler so you don’t lose material

                              Existing floor had failed under toilet due to inadequate structural support. Installed additional floor joists, covered with plywood, primed (with LevelQuik), then stapled metal lath to plywood. Mixed LevelQuik RS with 4.5 quarts of cold water for 2 minutes to a nice and smooth consistency. Poured to 1-1/2” thick depth (approximately: 4 sq-ft area) to meet fire code (multi-family housing). Completed floor repair is smooth and level.

                              Worked excellent, I put the max range of water mix in and it made the mix very manageable. Final product was very smooth, its hard to mess it up unless you just go way too slow or don't mix well. Definitely want a buddy system where someone is mixing the whole time with a one bucket in, one bucket out system. Great product. Estimate high for bag use, it doesn't go a long way if you have gaps more than 1/4"
