SUBSTRATE

Floor & Wall
Interior & Exterior
Bathrooms and Kitchens where should do waterproof & tile at the same time: Toilet/Kitchen/Wet areas of individual housings
Apply weber.prim 2 primer for reducing water-absorption before fixing tile

Not suitable to be used externally (instead use weber.dry tex waterproofing motar before using weber.tai flex).
Not suitable to be used on wood, cement-fiber board, gypsum plaster, painted surfaces (instead use weber.dry top waterproofing slurry before using weber.tai flex).
Not suitable to be used on metal and plastic substrates (instead use weber.color poxy as the adhesive and weber.color poxy as the grout).
Not recommended to use in swimming pool or any areas, where proper waterproof layer is required (instead use weber.dry tex waterproofing motar before using weber.tai gres).

Powder density 1.35 g/cm³
Bonding strength at dry stage (EN 1348) > 1.0 N/mm² Bonding strength after water immersion (EN 1348) > 1.0 N/mm²
Bonding strength after heat ageing (EN 1348) > 1.0 N/mm²
Water absorption & water uptake test : Pass
Note: These test results are from laboratory test. They could be slightly different from on-site results because of the differences in applications and conditions.

For new substrate: it should be flat, hard, level, dry, and clean with normal absorption.
For old substrate: scrape off any peel-off coatings or remove any de- bonding tiles and do the re-tiling.
Clean the surface until free from grease, dust, or any stains.
If the surface is very porous with high absorption, it should be wet until reaching its saturated point before tiling.
In case of new screed or render, the substrate should be fully cured for 7 days per 1 cm thickness of concrete before tiling.
For old substrates or existing tiles, it is recommended to clean with hydrochloric acid (cleaning chemical for bathroom) in order to make sure the adhesion on old tile substrate.
In case of flexible or bendable substrates; gypsum board, gypsum-fiber board for instance; it is recommended to frame and brace them with screw for every area of 900 cm2 (30 x 30 cm.).

Tiles should not be immersed in water because it will decrease bonding strength of the adhesive.
Ensure that tiles are clean, dry, free from grease, dust, or any other contaminations.

Put 5 liters of clean water in a bucket.
Gradually add weber.tai 2-in-1 (20 kg), by the weight ratio of 1 part of water per 4 parts of dry mortar (or 1:3.5 by volume) in water and mix at the same time by using slow speed; 500 rpm; electric mixer.
- When using traditional trowel, mix properly until homogeneous lump-free paste is obtained.
After proper mix, leave the product for 3 – 4 minutes before use in order to have the complete chemical reaction.
- The mixture of weber.tai 2-in-1 should be used within 4 hours and kept away from heat and sunlight.

Apply some adhesive onto the substrate covering the area of 1 – 2 m².
Use a suitable notched trowel to spread the adhesive evenly.
- It is strongly recommended to have adhesive buttered onto the tile back as well, this is to ensure the continuous layer of adhesive in order to achieve its water-prevention property.
- Adhesive buttered onto the tile back is a must.
Lay tiles on the adhesive and press firmly or gradually knock with rubber hammer.
- It is good practice to lift an occasional tile after fixing, to verify that the required contact is free from void.
- Leave appropriate clearance joints for grouting and make any adjustment within 15 minutes.
Carefully clean off any excess adhesive with a damp cloth or sponge from the tiles and joints before it sets.
Wait for 24 hours before grouting to let the adhesive dry completely.

In case of large-size tiles, avoid tiling traditionally (using traditional mortar for leveling and tiling at the same time). It is important to do leveling before tiling because it can prevent tile from de-bonding after opened for traffic and prevent the shrinkage of cement.
Avoid using the adhesive on red-hot substrates or the substrates exposing to direct sunlight.

To maintain straight joints, spacers should be used (as shown in the picture). The joint width is controlled by the width of spacer.
To protect water leakage into underneath tiles and to avoid tile movement when there is foot traffic, the joint width should be at least 1.5 mm for wall and at least 3 to 20 mm for floor.
In bathrooms and kitchens, weber.color power is recommended for grouting or weber.klin jcr primer before weber.color classic to protect the joints from fungus, dirt, soap stains, or cooking-oil stains.
