Blackfriar Professional Floor Sealer clear, solvent-based, alkyd sealer. Ideal for binding, stabilising and sealing friable (loose) and porous surfaces prior to finishing with solvent based coatings.


Surfaces should preferably be as dry as possible. Ensure the surface to be painted is sound, clean, dry and free from grease or any substance liable to give adhesion problems. Scrape off any old or flaking paint until you have a firm surface. Special attention should be given to areas under cars to ensure all oil, grease, dirt and road salt is removed.

New concrete must be left for at least 6 months before applying Blackfriar Professional Solvent Based Floor Sealer.


Stir thoroughly before use. Apply with a brush or roller working the paint in any surface imperfections. Blackfriar Professional Solvent Based Floor Sealer is not suitable for use over non porous substrates like PVC, thermoplastic tiles, quarry tiles, asphalt floors or granolithic concrete. Do not apply it on concrete surfaces treated with alkali containing liquids, areas subjected to rising damp or areas treated with PVA bonding solutions. Do not apply in cold (below 10°C), damp or humid conditions.

If concrete floors are very smooth then pre-treat with Blackfriar Professional Acid Etch followed after thorough rinsing by Blackfriar Professional Solvent Based Floor Sealer.

Drying Time

16hrs @20°C. Allow to dry for a minimum of 16hrs @20°C between coats. Full cure is achieved in 5-7 days @20°C.

Clean Up

Remove as much product from application equipment as possible before washing with white spirits. Do not empty into drains or watercourses. Some local authorities have special facilities for the disposal of waste coatings. Whilst every effort is made to ensure the accuracy of colour, due to limitations of the print process, colour/finish shown is for guidance only.

I have a concrete floor that was outside but now inside but did not have a membrane so want a sealer to stop any damp that may percolate through, and then paint it with floor paint.


We would suggest Blackfriar Professional Damp Proof Primer.
