  • Open time : 20-30 minutes
  • Adjusting time : 15 minutes
  • Recommended thickness : 2 - 10 mm
  • Waiting time before grouting : 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 use on exterior walls when;    
    • size of tiles bigger than 900 cm2 when tiling higher than 28 m. (instead use weber.tai flex).    
    • size of tiles between 900 to 1,600 cm2 when tiling higher than 8 m (instead use weber.tai flex).
  • Not suitable to use on glazing substrates, woods and painted surfaces (instead apply weber.prim 2 primer before using weber.tai flex).
  • Not suitable to use on light-weight concrete without cement render (instead use weber.tai maxx).
  • Not suitable to use on gypsump plaster board (instead use weber.tai flex or weber.fix plus(for humid area) or weber.fix pro(for general use)).
  • Not suitable to use with metal and plastic substrates (instead use weber.color poxy).

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.).

Tiles Preparation

  1. Using notched trowel to spread tile adhesive onto substrate
  2. Back buttering in case of laying tile bigger than 10 x 10 inches
  3. Placing tiles on tile adhesive and knock gradually with rubber hammer
  4. Clean the excess tile adhesive on tile surface
  5. Tiles can be adjusted within 15 minutes after laying
  6. Leave for 24 hours before grouting

Mixing

  • Put 5 liters of clean water in a bucket (the water should be at room temperature, not warm or hot).
  • Gradually add weber.tai gres (20 kg),
    • by the weight ratio of 1 part water per 4 parts of adhesive
    • or 1:3 by volume, in the water and mix at the same time by using slow speed (500 rpm) electric mixer.  Or mix properly with a trowel until homogeneous lump-free paste is obtained.
  • After proper mix, leave the product for 3 - 4 minutes before using in order to have the complete chemical reaction.
  • The mixture of weber.tai gres should be used within 4 hours and kept away from heat & sunlight.  

Application

  • Apply some adhesive on the substrate, and then use a notched trowel to equally spread the adhesive on the area of 1 - 2 m2.  The depth of the notched trowel is to control the constancy and quantity of adhesive.
    • For floor: spread the adhesive on the substrate with the notched trowel.     
    • For wall: better spread the adhesive horizontally with the notched trowel (as shown in the picture) on the substrate.    
    • Using notched trowel will ensure a better transfer of adhesive onto both tiles back and substrates than using brick-laying trowel.
  • In case of tile size exceeding 25 x 25 cm (10" x 10"), it is recommended to have adhesive buttered onto the tile back in order to ensure the overall covering of the adhesive onto substrate and also to prevent voids underneath the tiles, which could make tiles being fragile and allow water permeation.
  • Lay tiles on the adhesive and press firmly or knock gradually with rubber hammer in order to spread the notch of adhesive equally and ensure a good contact.  
    • Leave clearance joints, at least 2 mm, for grouting.
  • Carefully clean off any excess adhesive from the tiles and joints with a damp sponge while the adhesive is still wet.
  • Any adjustments can be done within 15 minutes before weber.tai gres sets.
  • Wait for 24 hours before grouting to let the adhesive dry completely.

Application Property

  • Pot life: 4 hours
  • Open time: 20 minutes
  • Adjustment time: 15 minutes
  • Time before grouting: at least 24 hours
  • Time before traffic: at least 24 to 48 hours
  • Recommended thickness: 2 to10 mm  

Recommendation for Use

  • In case of large-size tiles, avoid tiling traditionally (using traditional mortar for leveling and tiling at the same time) as shown in the picture 1.  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 2).  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.
