Acrylic Resin Sealer

CPR 906 – Acrylic Resin Sealer is a single pack, solvent-borne, clear Acrylic resin based curing compound, surface sealer and dust proofer for concrete. When applied to freshly placed concrete the Sealer functions as a curing membrane, reducing any tendency towards drying shrinkage cracks. At the same time the surface becomes sealed against the ingress of oils and many aqueous chemicals, and a harder wearing floor is produced.

When applied to old/aged concrete floor the Sealer penetrates into the pore structure thereby sealing and dust proofing the surface. Having excellent adhesion to concrete and allowing the application of subsequent paint/coating treatments, thereby minimising surface preparation requirements.

Typical Properties

  • Easily applied by brush, roller or spray
  • High curing efficiency (>75%)
  • Good chemical and abrasion resistance
  • Seals and dust proofs the surface
  • Compatible with most subsequent finishes
  • Provides easily cleanable floor surface
  • Internal and external use
  • Resistant to ultra violet radiation
  • Single pack – ready to use

Directions for Use

Surface Preparation

  • Old concrete shall be sound and free from oil, grease, laitance and other contaminants.
  • Previously applied paint or curing membrane must be removed.
  • Wash the floor with a detergent solution followed by a clean water wash, and then allow to dry prior to sealer application.
  • New concrete – CPR 906 may be applied 15 minutes after the final power float or brush finish.


  • Old concrete – Apply a coat of CPR 906 by brush, roller, squeegee or spray at a nominal rate of 8-9m²/litre.
  • Avoid the formation of puddles of excess material.
  • After a minimum period of 16 hours a second coat shall be applied at a rate of 11-12m²/litre NOTE: On very porous substrates a third coat may be necessary
  • New concrete – Apply CPR 906 by spray at a nominal rate of 5m²/litre.
  • Ensure that the material is applied evenly and avoid the formation of puddles of excess material on the surface.
  • In hot and/or windy conditions, a second coat of CPR 906 – Acrylic Resin Sealer should be applied the following day at a nominal rate of 8-10m²/litre

Equipment Cleaning


  • CPR 906 – Acrylic Resin Sealer will be tack free in 2-4 hours and hard dry after 16-24 hours in conditions of good ventilation.

Storage and Shelf Life

  • Store in dry conditions, out of direct sunlight, at temperatures between 10°C and 25°C.
  • CPR 906 has a minimum shelf life of 12 months when stored in original, unopened containers in accordance with manufacturer’s instructions.


  • CPR 906 – Acrylic Resin Sealer is supplied in 25L packs


  • Coverage is very much dependent on the porosity of the substrate.
    a. New concrete – Typical application rate is 5m²/l (one coat): a second coat is recommended under fast drying ambient conditions.
    b. Old concrete – For smooth, power floated concrete, the typical application rate is: 8-9m²/l (1st coat) 11-12m²/l (2nd coat) i.e. overall rate = 4.6-5.1m²/l(two coats)
  • If a slip resistant finish is required, incorporate CPR suitable aggregate and apply only 1 coat of CPR 906 – Acrylic Resin Sealer at a rate of 5m²/litre.
  • Textured and tamped finishes reduce the coverage rate achieved.
  • NB. It is strongly recommended that a small test application be carried out to determine the precise coverage rate for each specific job, prior to any large scale application being started.
