FLOW & LEVELLING ADDITIVES

Improves surface finish and reduces defects such as brush marks, orange peel, and roller stipple — helping self-levelling screeds and topcoats settle into a smooth, glass-like surface.

How levelling works

STEP 1 — DISTRIBUTION

Disperses through the film

The levelling agent distributes through the wet coating film as soon as it's applied, ahead of gelation.

STEP 2 — TENSION EQUALIZATION

Equalizes surface tension

By evening out surface tension gradients across the film, it counteracts the pull that causes ridges, cratering, and Bénard cells.

STEP 3 — SMOOTH FLOW-OUT

Film flattens before gelling

The film has time to flow and self-level before the resin gels, producing a smooth, uniform, glass-like finish.
