SUR-FACE CONCRETE RETARDER 10L
SUR-FACE – standard viscosity for horizontal work, e.g. precast panels, construction joints key or kicker joints etc.
For all grades of SUR-FACE the depth of retardation depends upon variables like
• The thickness of the coating,
• The time elapsed before the retarder is removed,
• The cement content and the quantity of water in the mix.
• The ambient temperature All SUR-FACE variants are non-toxic and biodegradable and comply with GREEN STAR- OFFICE DESIGN V3 IEQ-13.
Curing if specified of SUR-FACE slabs can only be effectively achieved with conventional wet cure methods, as membrane cures will interfere with the revealing process.
For vertical and ceiling applications use SUR-FACE TK.
For extended open times use SURFACE PLUS.
