Solvent free.
Bonds to concrete, wood, metal, aluminium, polyester, glass, uPVC, stone, ceramics, etc.
Over paintable with gloss and emulsion.
Good sea water resistance.
Can be over painted with oil and latex paints.
Specifically designed as an easy flow flooring grade for all concrete saw cuts and floor slab expansion joints, where abrasion resistance is required.

Approvals/ standards:

CE / UKCA Marked to types F EXT-INT CC and PW EXT-INT CC.
Solvent free (EMICODE EC 1PLUSR Very Low Emissions).
Passes LEED EQc 4.1, SCAQMD, Rule 1168 and BAAQMD, Reg 8, Rule 51.
