Substrate Preparation and Priming

• The surface should have a light even texture. Masonry should be flush pointed, and all defects in existing surfaces made good.
• Surfaces must be clean, dry, sound, and free from dust, grease, curing compounds, release agents, loose particles, efflorescence, concrete laitance, or any other contaminants.
• Corroded metal areas should be wire brushed and treated with an anti-corrosive primer.
• All high points and protrusions should be removed; blow-holes and areas of honeycombing should be filled, and the surface should be brought back to an even profile using a suitable repair mortar.
• Note: Due to the wide variety of substrates available, adhesion testing is recommended in a trial area before full application.
• Substrates that are porous and/or slightly dusty should be primed with a 1:5 dilution of Bitflex and water.
• If the substrate is not dry, prime the surface with Crommelin® WB2K®

Application

• Apply Crommelin Polyfab BB or Silicone bond braking sealant to internal angles and vertical angles as per standard.
• Note: Do not use Bitflex in conjunction with polyurethane or hybrid sealants.
• Apply the first coat of Bitflex as per the recommended coverage rate. Work from corners to central areas and allow it to dry.
• If only a bond-breaking sealant has been used, it is required to install Crommelin.
• Apply the second coat of Bitflex as per the recommended coverage rate, at 90 degrees.
• Allow at least 72 hours before installing protection board and backfilling.

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.
