Substantial, first-party technical guides covering paint chemistry, substrate diagnostics, crack remediation, colour under equatorial light, and professional trade sequencing for Kenya and East Africa.
Authoritative guidance on coating selection, substrate diagnostics, environmental suitability in Kenya, and trade specifications.
Our Knowledge Centre provides authoritative, applicator- and engineer-reviewed technical guides on paint formulation, substrate diagnostics (plaster, gypsum, concrete, structural steel, timber), crack and damp remediation, equatorial UV protection, and professional trade sequencing across Kenyan residential, commercial, and industrial sites.
Coastal locations such as Mombasa, Malindi, Kilifi, and Diani demand coatings with elevated salt-bloom resistance, micro-porous vapour permeability, and non-leaching fungicidal protection. For exterior walls, we recommend 100% pure acrylic elastomeric coatings or silicone-modified emulsions. For structural steel and industrial surfaces, two-pack polyamide epoxy primers followed by aliphatic polyurethane topcoats prevent chloride-induced pitting and corrosion.
The primary cause is moisture entrapment combined with active substrate alkalinity. Plaster in new buildings requires at least 28 days of cure time to drop below pH 9. Without proper damp-proof courses (DPC) or when leaks occur, moisture carries soluble mineral salts to the surface (efflorescence), breaking the paint adhesion film. Effective remediation involves eliminating moisture sources, neutralizing salts with an acid etch or wire brushing, applying a dedicated alkali-resisting primer (ARP), and finishing with high-solids breathable topcoats.
While epoxy coatings offer exceptional compressive strength and chemical resistance for standard warehouses, showrooms, and workshops, heavy-duty polyurethane (PU) screeds are required for facilities subject to severe thermal shock (-40°C to +120°C), steam cleaning, constant water exposure, or organic acids. This makes PU screeds the mandatory specification for commercial kitchens, dairies, meat processing facilities, cold storage, and chemical manufacturing plants across East Africa.
Kenya’s high altitude and equatorial sun deliver intense ultraviolet radiation (UV index regularly exceeding 11). Standard low-grade vinyl acetate emulsions degrade rapidly under this UV intensity, resulting in chalking, embrittlement, and fading within 12–18 months. Sienna Paints Kenya formulates exterior coatings with pure acrylic binders and inorganic, UV-stable pigments that resist photochemical degradation and maintain colour depth for 7 to 10+ years.
