How to Apply Alccofill WP

Prepare the Tile Joints

Ensure the tile joints are clean, properly formed and free from dust, loose particles, adhesive residue, oil or other contaminants.

Prepare the Product

As Alccofill WP is a single-component cementitious tile joint filler, prepare it according to the recommended water-to-product ratio and mixing instructions.

Mix Thoroughly

Mix until a smooth and uniform consistency is achieved. Avoid excessive water, as incorrect water addition can affect the final grout performance.

Fill the Joints

Apply the prepared grout into the tile joints using an appropriate grout float or recommended application tool. Ensure that the joints are completely filled.

Remove Excess Grout

Remove excess grout from the tile surface while it is still workable, taking care not to disturb the filled joints.

Finish the Joints

Finish the joints to achieve a smooth, uniform appearance according to the desired joint profile.

Allow to Set

Allow the grout to set and cure according to the recommended product instructions before exposing the tiled surface to regular use or moisture.
