Ceresit CT48 Silicone Paint - 3.5L
What is Cekol CT 48?
Ceresit CT 48 is a premium Silicone Facade Paint designed for protecting and decorating exterior walls. It is highly hydrophobic (water-repellent) and vapour-permeable (breathable), making it the ideal solution for rejuvenating old renders or painting new External Wall Insulation (EWI) systems. Its "self-cleaning" properties ensure that dirt and pollutants are washed away by rainwater.

- Can Ceresit CT 48 be used over old render?
Yes. Ceresit CT 48 is an excellent choice for renovating faded or weathered renders. Because it is highly breathable, it allows moisture trapped in the old substrate to escape, preventing the paint from bubbling or peeling, which is common with standard masonry paints. - Is Ceresit CT 48 self-cleaning?
Yes. The silicone resin creates a high-tension surface that causes water to bead and roll off. As the water moves, it picks up surface dust and pollutants, keeping the facade cleaner for longer and reducing long-term maintenance costs. - Do I need a primer before using CT 48?
For new or highly absorbent surfaces, it is recommended to use a compatible primer like Cekol GS-83 or CT 17. This ensures even absorption and maximum adhesion of the silicone paint.
- Preparation: Clean the facade using a low-pressure wash to remove dust, algae, and loose particles.
- Priming: Apply a deep-penetrating primer to stabilize the substrate and ensure even paint suction.
- Mixing: Stir the paint thoroughly. You may dilute the first coat with up to 5% water for better penetration on porous surfaces.
- First Coat: Apply evenly using a roller or airless spray.
- Second Coat: Wait 4–6 hours (depending on weather) and apply the second coat undiluted for maximum protection and color depth.
- Pro-Tip on Color Matching: When painting large elevations, always use paint from the same production batch to ensure 100% color consistency.
- Pro-Tip for Algae Protection: If the building is located near trees or in a high-humidity area, the silicone-based formula of CT 48 provides a natural defense against organic growth without the need for harsh chemical treatments.
