UltraFloor Prime IT Multi-surface Primer is a moisture tolerant, water-based acrylic primer, sealer and bonding aid, suitable for porous and non-porous substrates. Prime IT Multi-surface Primer has been designed to promote the adhesion of UltraFloor smoothing underlayments.
UltraFloor Prime IT MSP stabilises and consolidates the substrate surface and reduces the absorbency, enabling subsequent materials to flow, cure and bond successfully. It is recommended for use prior to the application of smoothing underlayments and between layers when multilayer applications are being carried out to minimise pinholes and maximise interlayer adhesion. UltraFloor Prime IT MSP can also be used as a curing agent for cementitious-based products, diluted 1:1 with water.
