Protect your roof with the SmartSeal Roof Tile Sealer. It is a clear, professional-grade, solvent-free acrylic-impregnating sealer for concrete, clay tile or slate roofs. Once applied, the tile sealer's chemical structure alters itself to produce an excellent water-repellent surface, restricting the growth of moss, algae and lichens. Use a handheld sprayer or brush for application purposes and apply to saturation. It's recommended that after once 20-30 minutes have passed, a light second 'wet on wet' coat should be added. If rain is forecasted or temperatures are below 10°C, do not attempt to apply the sealer. This roof tile sealer is designed to deliver quick results. With a touch dry time of just 2-3 hours, you can proceed with confidence, knowing that your surfaces will be ready in no time. Within 24 hours, this sealer will attain maximum water resistance, ensuring reliable protection against water damage and helping prevent the appearance of organic green growth like moss and algae. This roof tile sealer comes in a 25L pack. With just 25 litres you can treat up to 125 m² of concrete roof tiles ensuring comprehensive protection. For clay and slate roof tiles the coverage extends even further reaching 200 - 250 m² area.
