Do I need to prime floor before self Levelling?
Prime the Wood 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.
Do you need to seal self Levelling compound?
Primer is absolutely necessary if you have an anhydrite screed (aka calcium sulphate). This is a liquid screed pumped onto the sub-floor that self-levels. It’s quite common in modern construction and has many benefits over sand and cement screeds, but you can’t tile straight onto it with standard adhesives.

This is approximately 1 to 2 days for the Normal Set product or 2 to 4 hours for the Fast Set product, depending on surrounding conditions. No special curing steps are required. 4. When using the Normal Set product, wait 1 to 2 weeks before installing finished flooring over the resurfaced area.

Why is my self-leveling bubbling?
Concrete out gassing is one of the primary reasons for pinholes in self leveling cements and bubbles or fish-eyes in resinous flooring systems. When the air temperature is warmer than the slab, especially in a low humidity, vapor will leave the concrete slab.
What is the difference between self leveling concrete and self-leveling underlayment?
Self-leveling materials are typically cement products that will flow onto the surface of existing concrete, wood, terrazzo, metal or ceramic to create a smooth, even surface. Self-leveling materials are not underlayment and underlayment is not self-leveling material.
How many bags of self Levelling compound do I need?
Answer: you would require 16 bags, please bear in mind that this does not allow for wastage and that the area is a constant 20mm. in good drying conditions you should be able to walk on the levelling compound after 4-6 hours, at 20mm thick it will be ready to cover with floorcoverings after approximately 2 days.

How deep can self Levelling compound be?
Larsen’s Self Levelling Compound is a more traditional levelling compound. Suitable for use on most common subfloors such as sand/cement screeds or concrete. It has high flow properties making it ideal for smoothing. It can be laid up to 6mm in depth.
Can I paint self-levelling compound?
A: Our Concrete Floor Leveller is tougher than latex surface levellers and easily copes with vehicle traffic. Unlike traditional surface levellers it can also be painted over. It comes as a liquid and powder which you then mix to create a pourable product.
Can you use self-levelling compound outside?
Developed primarily for outdoor use, Tilemaster External Leveller is ideal for use externally where the making good of an existing sand / cement or concrete base is required, such as patio areas.

Can you put floor leveler on plywood?
If you’ve got a plywood subfloor, like many buildings do, you can leave it in place and apply self-leveling concrete directly on top of it. You can also use self-leveling concrete on plywood as an underlayment for other types of floor coverings, such as carpet or tile.
Can you tile directly on self-leveling compound?
Before you can lay a tile floor, you must make sure the subfloor is entirely flat. Contractors use pourable self-leveling compounds to smooth uneven floors before tiling them.
How soon can you self level over new screed?
For areas which receive heavier foot traffic or if you’re hoping to move or place heavy furniture on it, we recommend leaving it for around 5-7 days. Typically, most screeds will reach full cured strength after approximately 28 days. For the best results, it’s better to wait that long before using a screeded surface.
