Floor Sealers
Floor sealers are protective coatings that enhance the performance, longevity, and appearance of a wide range of surfaces. Designed to guard against stains, moisture, abrasion, and chemical exposure, they are suitable for use on concrete, stone, tile, vinyl, and coated floors.

Floor Sealers
Floor sealers are essential for maintaining the integrity and appearance of concrete, stone, and coated floors across a variety of environments. Whether applied to newly laid substrates or over existing coatings, sealers form a transparent or tinted layer that strengthens the surface and protects against moisture ingress, staining, and surface wear. This added durability helps prevent common issues like dusting, discolouration, and premature deterioration—especially in high-traffic or moisture-prone areas.
For concrete floors, a dedicated sealer can be used as a standalone finish or as a base coat beneath concrete floor finishes. In garages, sealers are frequently used to prepare the surface before applying heavy-duty garage floor paints or to dustproof untreated concrete where painting isn’t required. On exterior surfaces like patios, stone sealers can serve as an effective alternative to patio paints, helping to prevent efflorescence and weather damage while enhancing natural colour and finish. Whether protecting a natural substrate or extending the life of an existing coating, selecting the right sealer ensures long-term performance and ease of maintenance.
Floor Sealer FAQs
Can I use a floor sealer instead of paint on concrete?
Yes. While concrete floor paints offer colour and surface build, sealers are often used where a clear, dustproof, breathable finish is preferred - particularly in warehouses, utility areas, or storage units.
Are floor sealers suitable for garages?
Definitely. Floor sealers can be used to prep bare concrete or topcoat existing coatings in garages. For added surface strength, they can also be paired with compatible garage floor paints in high-traffic or vehicle-bearing areas.
Can I seal over a previously painted floor?
Yes, as long as the underlying paint is well-adhered and fully cured. Coated floor sealers are specifically designed to extend the lifespan of existing coatings by adding abrasion and UV resistance.
Are floor sealers slip-resistant?
Most sealers provide a smooth finish, but anti-slip additives can often be introduced during application for areas where slip resistance is important - especially in wet or external zones like patios.
Do I need to reapply a floor sealer over time?
Yes, most floor sealers will gradually wear and may need to be reapplied every few years - particularly in high-use or outdoor environments. Regular maintenance inspections will help determine when reapplication is required.
