Cemfloor certified

Cement based liquid screed in Exeter

Flowing screed with cement chemistry top to bottom — the mix we default to wherever tiles, water or thin heated build-ups are involved.

Why we pour Cemfloor

We're manufacturer-certified Cemfloor installers, trained by the maker, with every batch logged. The products we lay are Cemfloor CT-C30-F6 and Cemfloor Therm. Made in Ireland and pumped like any liquid screed, it keeps a cement binder throughout — so it gets on with tile adhesives, epoxy coatings and whatever wet trades follow.

Each pour carries Cemfloor's own product warranty on top of our workmanship guarantee, which is why a growing number of Exeter specifiers name it on the drawings.

Build-ups where it earns its place

  • Underfloor heating over suspended timber or PIR, where you want low cover and fast heat transfer.
  • Wet rooms, kitchens and basements — places a gypsum floor would be a liability.
  • Commercial slabs with SR1 written into the tiling spec.
  • Renovations where sand and cement simply won't dry inside the programme.
  • Large-format porcelain or LVT laid without an extra latex layer.

Thin over the pipes

Over wet heating we need just 30mm above the top of the pipe on a bonded build, or 35–40mm unbonded, against 65–75mm for traditional sand and cement. Less mass to warm means a more responsive floor. We confirm the exact figure on survey.

Drying, honestly

Allow roughly a millimetre a day for the first 40mm, slower beyond that. In normal conditions a 50mm floor is typically under 75% relative humidity inside three weeks. You can walk on it after 24–48 hours, and there's no compulsory laitance sand for most mixes — just the manufacturer-approved primer per the datasheet.

Choosing between the two

Tiles, water, or heating in the slab? Go cement. A purely dry residential floor under engineered wood where cost per m² leads? The anhydrite liquid screed may be the better fit. Deeper product detail sits on our Cemfloor screed page; prices and survey on screed floor installation in Exeter.

Common questions

Is Cemfloor the same as anhydrite?
No. Cemfloor is cement-based; anhydrite screeds such as Gyvlon and Gypsol are calcium sulphate. That changes drying, adhesive compatibility and wet-area suitability.
How quickly does cement liquid screed dry?
Rule of thumb: 1mm a day for the first 40mm, slowing after that. A 50mm pour typically reaches under 75% RH inside three weeks in normal conditions.
Can it go in a wet room?
Yes. Cement chemistry doesn't degrade under repeated wetting the way gypsum-based screeds can.
