Important Considerations

• ⚠️ Not suitable for areas of permanent water immersion
• ⚠️ Not suitable for negative hydrostatic pressure or rising damp applications
• ⚠️ Delay application if rain or inclement weather is imminent
• ⚠️ Must be applied at recommended coverage rates — do not over-dilute or under-apply
• ⚠️ Tongue & groove timber flooring must be over-sheeted with fibre cement or ceramic tile underlay
• ⚠️ Particleboard flooring must be adequately prepared with all contaminants removed
• ⚠️ Install finished covering as soon as possible once membrane has cured to minimise damage risk
• ⚠️ Not suitable as a wearing surface for foot or vehicular traffic

Colour accuracy disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
