CURE MECHANISM
Sikafloor® Marine VEM cures by way of hydraulic curing.
Application
Surface preparation
For applications, the surface has to be clean, free from dust, grease, oils and other substances, which may impair adhesion. Rust has to be removed with a steel brush or other appropriate means, followed by vacuum cleaning.
The surface has to be primed with Sikafloor® Marine Primer C using a long hair roller. After drying of the Sikafloor® Marine Primer C, Sikafloor® Marine VEM may be applied.
Sikafloor® Marine VEM applications on aluminum or zinc rich shop primer coated decks, require a tie coat of SikaCor® ZP Primer or another suitable tie coat prior the priming step with Sikafloor® Marine Primer C.
Application
Apply the mortar with an appropiate notched trowel in order to get a layer thickness of 1.5 ─ 2 mm.
Sikafloor® Marine VEM has to be applied within 30 minutes after mixing. At temperatures above 30 °C the open time will be reduced to 10 minutes or less.
For advice on selecting and setting up a suitable pump system, contact the System Engineering Department of Sika Industry.
Curing
After application, the finished areas have to be protected against direct heat (e.g. cutting or welding from beneath), sunlight and draught during the curing process for at least 12 hours.
Removal
Excess material can best be removed before curing with a trowel wipe or water.
Fresh Sikafloor® Marine VEM may be removed from tools and equipment with water. Once cured, the material can only be removed mechanically.
Exposed hands and skin shall be washed immediately with water. Use a suitable skin protection hand cream.
Application limits
For applications on slooping surfaces > 1 % contact the Technical Department of Sika Industry.
