Description
Concrete Drive & Block Sealer
CPR 910 – Concrete Drive & Block Sealer is a single pack, solvent borne, acrylic resin-based, surface sealer and dust-proofer for concrete and block paving. When applied to freshly placed concrete CPR 910 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 onto old concrete or blocks CPR 910 – Concrete Drive & Block Sealer penetrates into the pore structure thereby sealing and dust-proofing the surface.
Typical Properties
- Easily applied by brush, roller or spray
- Single pack – ready to use
- Good chemical and abrasion resistance
- Seals and dust-proofs the surface
- Resistant to ultra violet radiation
- Provides easily cleanable floor surface
- Internal and external use
Directions for Use
Surface Preparation
- Old concrete and block paving shall be sound and free from oil, grease, laitance and other contaminants. Previously applied paint or curing membrane must be removed. If required, wash the floor with a detergent followed by a clean water wash, and then allow to dry prior to sealer application.
- New concrete – CPR 910 – Concrete Drive & Block Sealer may be applied 15 minutes after the final power float or brush finish, or at any appropriate time thereafter.
Application
- Old concrete – Apply a coat of CPR 910 – Concrete Drive & Block Sealer by brush, roller, squeegee or spray at a nominal rate of 8-9m²/ltr. Avoid the formation of puddles of excess material. After a minimum of 12 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 910 – Concrete Drive & Block Sealer by spray at a nominal rate of 5m²/ltr. 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 910 – Concrete Drive & Block Sealer should be applied at a rate of 8-10m²/ltr. - Block Paving – Ensure material is applied to fully seal the surface. Coverage is dependent on the porosity of the block.
Equipment Cleaning
- Clean equipment with CPR 201 – Tool Clean Solvent prior to curing of the coating.
Curing
- CPR 910 – Concrete Drive & Block Sealer will be tack free in 2-4 hours and hard dry after 20-24 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.
- Do not expose to freezing conditions.
- CPR 910 – Concrete Drive & Block Sealer has a minimum of 12 months shelf life when stored in original, unopened containers in accordance with manufacturer’s instructions.
Packaging
- CPR 910 – Concrete Drive & Block Sealer is supplied in 25ltr drums.
Coverage
- Coverage is very much dependent on the porosity of the substrate.
- New concrete – typical application rate is 5m²/ltr per coat. A second coat is recommended under fast drying ambient conditions.
- Old concrete – for a smooth power floated concrete the typical application rate is 8-9m² first coat, 11-12m² second coat. i.e. overall rate = 4.6-5.1m²/ltr for 2 coats.
- Block paving – dependent on the type of block – typically 2-4m²/ltr.
