Mapei Structural Epoxy Adhesive Kit, 6Kg, Ideal for Anchoring and High-Strength Repairs in Concrete and Steel

Mapei Adesilex PG4 Kit 6kg is a ready-mix epoxy mortar designed for bonding tiles and grouting in both interior and exterior settings. It combines an epoxy resin with a hardener to create a water-resistant, high-strength bond suitable for wet areas, walls, and floors, including pools, balconies, bathrooms, and wetrooms.

Adesilex PG4 bonds well to most common substrates such as concrete, cementitious screeds, plaster, terrazzo, and existing ceramic or porcelain tiles, provided the surface is clean, sound, and properly prepared.

Yes. The epoxy composition provides excellent water resistance, making it suitable for bathrooms, wetrooms, balconies, and swimming pools.

Adesilex PG4 is epoxy-based, delivering stronger adhesion, superior chemical and water resistance, faster initial bond, and a longer open time for tile repositioning, with no need to add water during mixing.

The kit contains pre-measured epoxy resin and hardener. To prepare, combine the two components as instructed, mix to a smooth creamy consistency, and proceed with application without adding water.

Prepare the substrate (clean, sound, and dry as required). Mix the resin and hardener according to the kit directions until smooth. Apply a thin bedding with a trowel, set the tiles, and adjust before the mortar tightens. Wipe and clean excess adhesive after placement.

Open time is the period in which you can reposition tiles after placing them. It varies with temperature and humidity, and is typically longer than cement-based adhesives. Always follow the kit’s guidelines for optimal performance.

Yes. Ensure the substrate is clean, sound, and appropriately prepared. Some substrates may require priming or specific surface treatment as recommended by the product instructions.

Wear appropriate gloves and eye protection, ensure good ventilation, avoid skin contact, and wash exposed skin with water if contact occurs. Keep away from children and store the kit in a cool, dry place.

Exposure to heavy traffic or immersion should wait until the epoxy mortar has fully cured according to the kit’s curing guidance, which depends on ambient conditions.

Epoxy bonds are typically very strong, and removal can be challenging. If re-tiling is necessary, plan for careful detachment and surface protection, following appropriate techniques.

For larger jobs, the Adesilex PG4 Kit 12kg provides similar epoxy bonding performance with more quantity per kit. The Kerapoxy epoxy grout kit offers epoxy grout separately for joints (not a bonding mortar). If you’re considering a variant, Adesilex PG3 Kit (5kg) is a smaller alternative with a similar epoxy bonding concept. See the following product options for comparison:
