- Concrete sealing protects concrete surfaces from water ingress, chemical attack, staining, abrasion, and UV degradation, significantly extending their functional and aesthetic life.
- Sealers are applied to driveways, floors, patios, pathways, parking areas, industrial floors, and structural concrete facades across residential and commercial properties in Kenya.
- Types of sealers include penetrating sealers, acrylic film-forming sealers, epoxy coatings, polyurethane topcoats, and specialised chemical-resistant coatings.
- Surface preparation — cleaning, degreasing, crack repair, and profiling — is the most critical determinant of sealer adhesion and longevity.
- Sealed concrete is significantly easier to clean and maintain, and the right sealer can enhance the colour and texture of the surface as well as protecting it.
- Bestcare Facilities Management provides professional concrete sealing and protective coating services across Nairobi and Kenya.
Concrete is inherently porous. Without surface protection, it absorbs water, oils, chemicals, and biological contaminants that stain the surface, degrade the cement matrix, and accelerate deterioration. In Kenya’s climate — where intense rainfall delivers large volumes of water to outdoor concrete surfaces, and where the dry season brings UV radiation and heat that causes surface carbonation and dusting — unprotected concrete deteriorates far faster than it needs to.
Concrete sealing addresses this vulnerability by applying a protective barrier — either at the surface or within the pore structure of the concrete itself — that prevents water, chemicals, and contaminants from penetrating. The result is a concrete surface that is more durable, easier to clean, more resistant to staining, and in many cases more visually attractive. For commercial and industrial properties in Kenya, where concrete floors, driveways, and facades represent major capital assets, professional concrete sealing is a cost-effective maintenance investment that protects these assets and reduces long-term maintenance costs significantly.
Types of Concrete Sealing Services
Penetrating Silane/Siloxane Sealers penetrate deep into the concrete pore structure and chemically bond with the cement matrix, creating a hydrophobic barrier that repels water without changing the surface appearance. These are ideal for external concrete, driveways, and architectural facades where a natural appearance must be maintained.
Acrylic Sealer Application applies a clear or tinted film-forming sealer to concrete surfaces, providing surface protection and a wet-look or gloss finish that enhances the colour and texture of the concrete. Acrylic sealers are popular for decorative concrete, stamped concrete, and exposed aggregate surfaces.
Epoxy Floor Coating provides a hard, chemical-resistant, seamless surface coating for concrete floors in warehouses, factories, laboratories, car parks, and commercial kitchens. Available in a wide range of colours with optional anti-slip aggregates.
Polyurethane Floor Topcoat is applied over epoxy base coats or directly to concrete to provide a UV-stable, abrasion-resistant floor finish with excellent chemical resistance — commonly used as the final coat in high-performance floor systems.
Densifier and Hardener Application applies lithium, sodium, or potassium silicate compounds to concrete floors, chemically reacting with the concrete to increase surface hardness, reduce dusting, and improve abrasion resistance — particularly valuable for industrial and warehouse floors.
Anti-Carbonation Coating applies a breathable, elastomeric coating to concrete facades and structural elements to prevent carbonation — the chemical process that destroys the passive protection of reinforcement bars and initiates corrosion — extending the structural service life of the concrete element.
