Cekol DL-80 - deep penetrating primer - 5kg
What is Cekol DL-80?
Cekol DL-80 is a professional-grade Deep Penetrating Primer designed to strengthen porous, weak, or chalky substrates. By soaking deep into the surface, it binds loose particles together, reduces water absorbency, and creates a stable foundation for adhesives, renders, and self-levelling compounds. It is an essential preparation step for old brickwork, aerated concrete, and gypsum plasters.

- When should I use Cekol DL-80 instead of a standard primer?
Use Cekol DL-80 when the wall is "dusty" to the touch or if it absorbs water almost instantly. Standard primers only sit on the surface, whereas the deep-penetrating formula of DL-80 enters the pores of the material to strengthen it from the inside out. - Can Cekol DL-80 be used before floor levelling?
Yes. Priming with DL-80 is critical before applying self-levelling compounds. It prevents the dry floor from sucking moisture out of the fresh compound too quickly, which stops air bubbles from forming and prevents the floor from cracking. - Is Cekol DL-80 solvent-free?
Yes. Cekol DL-80 is a water-based, solvent-free emulsion. This makes it safe for use in poorly ventilated indoor areas and ensures it is environmentally friendly while remaining highly effective for exterior renovations.
- Preparation: Clean the surface of loose debris and peeling paint. Ensure the substrate is dry.
- Application: Apply the primer undiluted using a brush or roller. For extremely absorbent walls (like thermal blocks), a second coat may be necessary.
- Check for Saturation: The goal is to saturate the surface without creating "puddles" or a shiny film.
- Drying: Allow it to cure for at least 2–4 hours. In cold or humid conditions, this may take longer.
- Next Step: Once dry, you can proceed with Ceresit ZU adhesive or any Cekol levelling mortars.
- Pro-Tip for Old Walls: If you are renovating a Victorian-era brick wall that feels "sandy," Cekol DL-80 is the best tool to stop the sand from falling away, providing a solid surface for new render to grip.
- Pro-Tip on Dilution: Unlike some primers, DL-80 is ready to use. Do not dilute it with water, as this will reduce the concentration of the resins and prevent them from binding the substrate effectively.
