Vetoset CA549

The substrate should be sound, clean, free from loose material, grease, laitance, dirt, curing compound, or any other substance that might impair bond quality with the substrate.

Concrete, hollow blocks, and cement-based substrates must be sufficiently cured and irrigated by water 1hour before application. The surface should appear damp with no water pooling.

Gypsum boards, plasterboards, anhydrite screeds must be sufficiently dry and free from dust.

For the preparation of mortar adhesive, pour into a container 5-6.6 liters of water for each 20kg bag of Vetoset CA549. 

Add the powder to the water and mix for 3-4 minutes using a low- speed electric drill fitted with a suitable paddle until achieving a uniform, lump-free consistency. Allow the mixed material to stand for about 10 minutes and remix briefly without adding further water.

Apply the mixed mortar adhesive in a thin layer, and firmly press it onto the surface that will be tiled and work with the trowel’s flat edge. Comb the adhesive with a suitable notched trowel horizontally to achieve a 2 - 6 mm bed thickness. Spread the mortar adhesive to a manageable area that can be tiled within 5-10 minutes. Press the tiles firmly over the mortar adhesive and immediately knock them into the desired position. Adjust the position of the tiles, if required, within its adjustability time of 10 minutes after installation.

Use the back buttering method for large tile format (any tile with a breadth of more than 40cm) applications. Apply and comb the adhesive on the surface to be tiled. Also, add the adhesive to the backside of the tile with/without combing.

Allow the installed tiles to remain undisturbed for at least 24 hours.

Clean tools and equipment with water immediately after use. Remove the hardened material using mechanical means.
