Self-Coat
Screed
ZERO V.O.C. E.M.T.
SCREEDING
DESCRIPTION
An Polymer based
floor screed for high impact areas.
PRINCIPAL
CHARACTERISTICS
Floor screed. High
film builds to cover irregular surfaces. Good
impact resistance. Suitable for floor surfaces.
Good waterproofing qualities. Has excellent
abrasion resistance ideal for vibrating structures
i.e. bridges and airports, is non-toxic and ZERO
H.A.P.

APPLICATION
Supplied ready for
application. Stir contents thoroughly before
application. Clean equipment with water before
touch dry state. If the screeding is applied to
thick, there will be cracks. If it is necessary
that the screeding must be a thick application, it
should be done in layers.
SURFACE PREPARATION
Ensure all traces
of loose friable materials; dirt, oil, and debris
are removed. Freshly cast conventional screeds must
be allowed to dry thoroughly before application of
SELF-COAT BIND and SCREEDING. Bulk concrete to
cure for 28 days minimum before application.
Surfaces to be primed with SELF-COAT BIND.

THEORETICAL
SPREADING RATE
The theoretical
spreading rate stated here is for DFT of 2 mm on a
smooth surface for reasons of convenience and
comparison. The user must calculate the practical
spreading rate.
