Mapei manufactures different primers for different applications:

• Primer G – for absorbent surfaces such as plaster or concrete
• Eco Prim Grip Plus – for smooth or non-absorbent substrates like tiles or metal
• Primer MF – for damp-proofing or special industrial applications

Using the correct primer improves adhesion, reduces dust, and ensures a more durable finish. Ask our team if you’re unsure which product to use.

• Adesilex P9 – standard-setting, suitable for most ceramic and porcelain tiles
• Ultralite S1 – lightweight adhesive for large format tiles and walls
• Mapeflex MS – suitable for flexible or challenging substrates

Our team can advise on the best adhesive based on tile type, floor condition and environmental factors.

Mapei offers dedicated tile and grout cleaners that are safe for use on most tiled surfaces. For general maintenance, pH-neutral cleaners are recommended. For tougher jobs, Mapei also offers deep cleaners that help remove residue, limescale or grout haze. Always follow the manufacturer’s instructions and test in a small area first.

Mapei sealers are used to protect porous materials such as natural stone, terracotta, and grout joints. They help prevent staining, moisture ingress, and discolouration without altering the appearance of the surface. These products are ideal for both domestic and commercial tile installations where longevity is essential.
