How to use


Surface preparation

Prior to application, ensure that the surface is completely dry, clean, free from dust, grease, and cement film. Residues from grease or soap can be removed with Alfix Deep Cleaner


Always test on a small, less visible area to confirm suitability for each type of tile. Some surfaces may appear darker or lighter after treatment.
Does not protect against corrosion caused by eg acid stains.

Glazed tiles are unsuitable for treatment with impregnator. On surfaces with a honed or polished finish or non-absorbent surfaces, wipe off excess sealer immediately after application.
For newly grouted surfaces allow min. 48 hours before treatment.

How to use

Apply Alfix Impregnator with a paint pad, cloth, brush, or paint roller. Wipe off any surplus product that has not penetrated the surface within approx. 5 min. with a dry and clean cloth. Apply a second coat after a drying time of approx. 30 min.

Allow at least 2 hours after last application before confirming whether the surface has become fully water repellant. If not, repeat procedure.

Keep surface dry for 24 hours until full cure is achieved. Foot traffic may begin after 2 hours.
For daily cleaning and maintenance of ceramic tiled surfaces, use Alfix cleaning products.
