There’s no need to use a PVA before you use a self levelling compound. However, it is advised that you clean and prime the surface before pouring over the cement mixture.

What is the cheapest way to level a concrete floor?

There are self-leveling coatings designed to fill gaps and cracks. You could also try using vinyl floor tiles to make the transition more gradual. Probably the easiest (and cheapest) thing to do would be to get a big diamond grinding wheel and bevel down the lip.

How thick should self-leveling compound be?

The minimum thickness advised for many levelling compounds is only 2 or 3 millimetres (some require a minimum of 5mm). And whilst even a millimetre less than the prescribed minimum might not seem that significant, it can cause problems.

Do I need to prime floor before self Levelling?

Wood floors need to be primed before covering them with self leveler. The floor will be covered with water-saturated leveler, which will cause the wood to swell. It will shrink back down when it dries, which could cause cracks in the underlayment and tiles above. The primer prevents the wood from absorbing water.

How deep can you self level?

How much water do I need for a 25kg self-leveling compound?

How much concrete leveler do I need?

At half-inch thickness, a 50-pound bag of Concrete Leveler will sufficiently cover 12 to 15 square feet. For a quarter-inch-thick application, the same size bag would cover between 24 and 30 square feet.

What happens if you add too much water to self-leveling compound?

Too much water in a screed mix will mean that you are going to get increased shrinkage, and with it more risk of cracking, and you could be left with a weaker screed. A wet screed is going to make it hard to achieve a good finish, and you may end up with surface dusting due to high water contents.

Why did my self leveling concrete crack?

A DIY self-levelling cement job might look good for a few months, maybe even a couple years. But if it’s not done properly, eventually it can start to crack. If your floors move or bounce, that cement can crack, too.
