Description
Chemforce Fortifier Plus Consolidating Sealer is an impregnating, permanent consolidator and water repellent formulated for premium protection from salt spalling and freeze-thaw spalling on very porous building materials. Genuinely porous stone and masonry (travertine, sandstone, limestone, precast concrete, cast stone, terracotta, grout and porous bricks) are all specifically rated as suitable surfaces, giving it real range across both natural stone and cementitious materials.
Its non film-forming chemistry retains the material’s natural colour rather than leaving a visible coating, and it’s fully breathable, letting water vapour escape freely and avoiding the harmful moisture build-up a film-forming sealer can trap inside the material. It’s totally resistant to UV and holds up well in alkaline environments, a genuine consideration given how corrosive concrete’s naturally high pH can be to lesser sealing technologies over time.
Full cure takes up to 4 weeks to build a structure deep inside the pores of the material, with the consolidating effect increasing the surface’s strength by up to 40%: a meaningful boost, though not enough on its own to make an unsuitable, very soft stone fit for a demanding salt water or freeze-thaw environment. For surfaces in regular contact with salt water, such as the splash zone around a saltwater pool, dip sealing: fully submerging the material for a minimum of 15 seconds before installation: is required to achieve the best result.

Where to Use
- Saltwater pool surrounds and splash zones
- Cladding, paving, blockwork and brickwork
- Grout, travertine, sandstone, limestone and precast concrete
- Residential and commercial indoor and outdoor surfaces
How to Apply
- Test first: apply to a small area and allow 24 hours cure time to check results.
- Prepare the surface: ensure it’s dry, clean and free of residues, at 5 to 35°C.
- Apply generous coats: 2 coats on horizontal surfaces at least 10 minutes apart, or 4 lighter coats on vertical surfaces.
- Remove excess residue: polish off thoroughly with clean, white absorbent cloths before it dries.
- Allow to cure: at least 2 weeks before contact with salt water or solvents.
Important Notes
- Will not prevent acid etching or physical wear of the surface.
- Highly flammable: flash point below 23°C, classified as a Dangerous Good.
- Not suitable as a substitute for a genuine waterproofing membrane.
