Used for priming well-prepared concrete surfaces prior to the application of Proma self-levelling underlayments or concrete repair mortars (ideal for porous concrete surfaces). Pro Prime LP MUST be diluted with water prior to use (provides extended coverage and cost savings - see technical data sheet for proper recommendation). Applied using roller, broom, or applicator gun. Quick drying - apply materials 30 minutes after application, or when product is dry, transparent, or tacky.
