DESCRIPTION
CEMIX RUBBERGUARD is an elastomeric one component waterproofing membrane, designed for a range of trade and DIY under tile waterproofing applications. Based on high performance polymer technology, RUBBERGUARD offers an easy to use membrane free of solvents and isocyanates. CEMIX RUBBERGUARD offers excellent adhesion properties over many substrates including concrete, masonry, renders, cement sheeting, wet area sheet surfaces and plaster board. RUBBERGUARD is fully compatible with the CEMIX range of screeds and tile adhesives.
TYPICAL APPLICATION/USES
CEMIX RUBBERGUARD can be used for:
ADVANTAGE
COVERAGE
Approximately 1.5 Sq m per litre for general wet area applications.
SUBSTRATE PREPARATION
Concrete substrates should be sound & primed (CEMIX ROCKET PRIME or CEMIX CEMLASTIC) to ensure a good bond. The substrate should be uncoated & clean, free from all contaminants, loose particles, dirt, oil, mould, curing compounds, sealers & paints etc. Vacuuming may be required to prepare the surface depending on substrate condition. Washing with soap & water blasting may also be required if oil is present. Cracks should be repaired with a suitable Cemix repair product. The better the substrate preparation & condition the better the end result. The concrete substrate should ideally be at least one month old.
DETAILING
As a wet area membrane CEMIX RUBBERGUARD requires a suitable bond breaker at all substrate junctions. The Cemix Safeguard detailing tape is recommended to be used.
LIMITATIONS
PACKAGING
CEMIX RUBBERGUARD is available in 4L & 15L.
STORAGE & SHELF LIFE
Can be stored in its original packaging in a dry place well sealed for a period of 6 months after production.
APPLICATION
CEMIX RUBBERGUARD membrane should be lightly stirred before using, and can be applied to both vertical and horizontal surfaces using a roller or brush. A minimum of two coats is recommended to be applied, at a minimum coverage of 1.5 Sq m per litre for general wet area applications.
