Before you apply
A primer is not universally compatible with every paint or existing finish. New concrete must meet the selected system's curing and moisture requirements; remove contamination and obtain confirmation if the substrate or old coating is uncertain.
Frequently Asked Questions
What is a concrete floor primer and why is it important?
What is a concrete floor primer and why is it important?
A suitable primer can prepare or control absorption in concrete where specified for the coating system. A dustproofer or sealer may have a different role; none repairs structural defects or guarantees that paint will never peel.
When should I use a primer on a concrete floor?
When should I use a primer on a concrete floor?
Follow the selected topcoat and primer instructions. Bare or porous concrete may need priming, but new concrete must first meet curing and moisture requirements; a primer does not make damp or weak concrete suitable.
Can concrete floor primers be used on old or previously painted floors?
Can concrete floor primers be used on old or previously painted floors?
Only where the primer is compatible with the sound existing surface and any retained coating. Remove contamination and loose material, and obtain system confirmation if the old finish is uncertain.
Are concrete floor primers suitable for both indoor and outdoor use?
Are concrete floor primers suitable for both indoor and outdoor use?
Check the exact primer's stated interior/exterior uses and compatibility with the topcoat. Do not assume every concrete primer is suitable outdoors or for persistent moisture.
Can I apply concrete floor primer myself?
Can I apply concrete floor primer myself?
Follow the product-specific method, protective-equipment and ventilation guidance. Inspect and prepare the concrete first; seek specialist advice for damp, weak or contaminated surfaces.
Will using a concrete floor primer improve the lifespan of floor paint?
Will using a concrete floor primer improve the lifespan of floor paint?
The correct compatible primer can support adhesion and absorption control where specified. It is not a guarantee of a particular lifespan and cannot compensate for moisture, unsuitable substrates or inadequate preparation.
