Mapei Ready-to-Use Fast Track Patching Compound, 4Kg, Suitable for Quick Levelling Under LVT and Resilient Flooring - Pack of 4

Mapei Planiprep Fast Track Alu Box 4x4Kg is a professional-grade substrate preparation powder designed to prime and strengthen the surface before tiling. Packaged as a 4x4kg Alu Box, it contains an accelerator and hardener that speed up curing, allowing you to start tiling sooner after substrate preparation.

It’s intended for preparing substrates prior to tile installations and is suitable for both indoor and outdoor applications. It supports bonding of ceramic tiles, natural stones, and other tiling materials, and it works on heated or slightly damp substrates when used as directed.

The accelerator and hardener included in the Alu Box accelerate the drying and hardening process, helping you move on to tiling sooner than traditional Planiprep formulations while still delivering a strong bond to the substrate.

Key specs include: 4x4kg Alu Box packaging, ultra-rapid hardening modified cement-based powder, indoor/outdoor use, suitable for heated and slightly damp substrates, designed to improve adhesion and strength, and intended for larger tiling projects with easy storage for future use.

Ensure the surface is clean, free of dust, oils, and loose material. Repair any cracks or irregularities, remove debris, and allow the substrate to reach a stable, dry state. A properly prepared substrate helps maximize adhesion and performance.

Mix the powder with clean water according to the bag instructions until you achieve a smooth, workable consistency. Apply using a notched trowel to create an even bed. Follow the product’s set-up guidelines to ensure uniform thickness and bonding readiness.

Because this is a fast-track formulation, you can typically begin tiling after the initial set has begun and the surface feels firm to the touch. Always verify the surface is stable and free of dust before laying tiles.

Coverage depends on the substrate condition, bed thickness, and tile size. Planiprep products are designed to provide solid bed integrity, but exact coverage will vary by project. Refer to the packaging for guidance based on the intended bed thickness.

Wear appropriate PPE such as gloves, eye protection, and a dust mask. Work in a well-ventilated area, avoid skin contact with the dry powder, and wash hands after handling. Store the Alu Box in a dry place away from moisture.

Alternatives include other substrate preparation or planing products from Mapei that are available on Fepy.com. For example, standard Planiprep formulations and other Mapei surface preparation products can offer different setting times and substrate compatibility. Compare them to Planiprep Fast Track for differences in curing speed and application rules, and choose based on your project’s timeline and substrate needs. Example alternatives you might see on Fepy.com include standard Planiprep variants and related Mapei preparation products (URLs below are representative of how these items are typically listed on the site):

Use Planiprep Fast Track when you need a reliable substrate prep that lets you tile sooner, such as renovations, large tiling installations, or projects with tight schedules. It works well on concrete or cementitious substrates and is suitable for indoor and outdoor environments, including heated floors, where a quick setting base is advantageous.

Store the 4x4kg Alu Box in a dry, temperate area with the container tightly closed when not in use. Cementitious prep products typically have a shelf life of months to a year depending on storage conditions; check the packaging for the exact shelf life and any storage notes.
