  • Ideal for tile-it-yourself in wet areas of your house. e.g. bathrooms and kitchens
  • Very good bonding strength
  • Suitable for any kind and sizes of tiles
  • Tiles can be adjustable for long period due to longer open time
  • Loner pot life allows the mixture standing longer for use (keep away from heat and sunlight )
  • Tiles are adjustable within 15 minutes
  • Tiles floor can open for foot traffic after 24 hours

    • Remark: These test results are from laboratory test. They could be slightly different from on-site results because of the differences in applications and conditions.

Limit of Use

  • 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).

Application

Surface Preparation

  • 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.).  

Tile Preparation

  • 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.

Mixing

  • 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.  

Application

  • 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.

Application property

  • Application temperature: 5oC to 45oC.
  • Not to be used on very cold substrates. 
  • Avoid applying in direct sunlight or on very hot substrates. 
  • Adhesive buttered onto the tile back is a must.
  • It is important to do leveling before tiling.
