Words From Our Valued Clients

4.8/5

Self-levels perfectly without extra trowel work

I was surprised at how well this self-levels. I didn't have to do much trowel work at all; it just found its own level perfectly. Saved my back!

Dave S. (Plasterer)

Perfect for encasing electric heating mats

Used this to encase electric heating mats in a conservatory. It covered the cables completely without any air pockets or shrinking. Tiles went down a treat.

Heating Solutions Ltd

Handles extreme floor variations without cracking

I had a floor that dipped from 2mm to about 15mm in the corner. This handled the variation in one pour without cracking. Very impressive.

Ian R.

Ready for foot traffic in 90 minutes, exactly as promised

They say 90 minutes for foot traffic, and they are right. I poured it at 8am and was walking on it by tea break.

Mike T.

Bonds perfectly over timber without cracking

Overlayed my floorboards with 15mm ply and primed it. This leveller bonded well and has shown zero signs of cracking despite the timber movement.

J. Evans

Glass-like finish requires minimal sanding

Left a glass-like finish. I laid LVT (vinyl tiles) directly on top with barely any sanding needed. Will definitely buy again.

Sarah P.

Single-part bag is easier and more eco-friendly

I used to use the two-part latex bottles, but this single-part bag is so much easier. Just add water and mix. Less plastic waste too.

GreenBuild Co.

Consistent quality across entire pallets

We've gone through 3 pallets of this on a commercial job. Every bag mixed up exactly the same. No dodgy batches.

The secret weapon for levelling old house floors

Old houses never have flat floors. This stuff is my secret weapon for getting a level base before tiling. Good price too.

Harry K.

No shrinkage cracks even on deep pours

Often with deep pours, you get shrinkage cracks next to the wall. This stayed perfectly intact right to the edge.

ProFinish Tiling

Bridges gaps between different floor materials perfectly

Used it on concrete and then over a patch of timber in the same room. It bridged the gap perfectly.

Emma L.

Professional results that impress customers

My customers always comment on how professional the floor looks before I even put the tiles down. It gives confidence in the rest of the job.

Your Questions, Answered

Do I need a latex additive?

No. This is a "single part" flexible leveller, meaning the polymer is already in the powder. You simply mix it with clean water, saving you the cost and hassle of buying separate bottles of latex liquid.

Can I use this outside?

No, BritLevel Flexible is specified for Interior Use Only. For external levelling, you would need a dedicated external-grade compound that is frost resistant.

How soon can I tile over it?

It is a rapid-setting formula. It accepts light foot traffic after 90 minutes, and you can generally begin tiling after a 2-3 hour period, depending on the ambient temperature and thickness of the layer.

Is it safe for Underfloor Heating?

Absolutely. It is compatible with both matted and piped underfloor heating systems. We recommend covering the heating elements with a minimum of 5mm of compound to ensure heat distribution and protection.

What is the maximum depth I can pour?

This compound is designed for a bed thickness of 2mm up to 18mm in a single application. This versatility makes it perfect for both fine smoothing and filling deeper hollows.

Can I use this on wooden floors?

Yes, BritLevel Flexible is suitable for pre-strengthened wooden floors. The polymer modification gives it the necessary flexibility to cope with the slight movement of timber substrates, provided they are screwed down securely and primed.
