Latex Floor Screed London — Thin-Bed Screed

What is latex floor screed?

Latex screed is a thin, self-levelling, flexible screed made from cement, fine aggregates and a polymer (latex) modifier. It produces a smooth, hard surface at thicknesses as low as 3 mm — perfect when overall floor height is constrained.

When should latex screed be used?

Latex screed is the right choice when you need a smooth surface for tiling, vinyl, or resin on an existing substrate without raising the floor level significantly. Common applications: kitchen and bathroom refurbishments, retail fit-outs, overlay on damaged concrete, levelling before LVT.

How thin can latex screed be laid?

Latex screed can be laid as thin as 3 mm and up to around 15 mm depending on the substrate and product specification. This makes it the thinnest screed option available — ideal where door thresholds and step heights are fixed.

Is latex screed underfloor heating compatible?

Latex screed can encapsulate electric underfloor heating mats but is too thin for water-based UFH systems, which require 40–50 mm cover. For water UFH, choose Anhydrite or Cemfloor instead.

How is latex screed installed?

The existing substrate is cleaned, repaired and primed (see our preparation guide for the full sequence). Latex screed is mixed on site, poured and worked across the floor with a smoother. It self-levels within minutes and is touch-dry in 1–2 hours. Most areas accept floor finishes within 24 hours under normal conditions.
