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 (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 substrate, wooden surface, or existing tile, it is recommended to apply weber.prim 2 primer before tiling.
  • In case of flexible or bendable substrates; gypsum boards, gypsum-fiber boards, fiber boards for instance; it is recommended to frame and brace them with screw for every area of 900 cm2 (30 x 30 cm.)  

Tiles 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.


  • weber.fix pro is a ready-to-use tile adhesive, no water required. Just mix the product until a homogeneous paste.
    • After proper mix, the product should be left for 3 to 4 minutes before using in order to get the complete chemical reaction.  
  • Apply some paste adhesive on the wall, and then use a notched trowel to equally spread the adhesive horizontally on the area of 1 - 2 m2
    • The depth of the notched trowel is to control the constancy and quantity of adhesive.
  • 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 after fixing tiles on the substrate, which could make tiles being fragile and allow water permeation.
  • Lay tiles on the paste 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 of any excess adhesive on the tiles and joints with a damp sponge when the adhesive is still wet. 
  •  Any adjustments can be done within 10 to 20 minutes before weber.fix pro sets.
  • Wait for 24 hours before grouting to let the adhesive dry.

Application Property

  • Pot life: 30 minutes
  • Open time: 10 to 20 minutes
  • Adjustment time: 10 minutes
  • Time before grouting: at least 48 hours depending on substrate and tile 
  • Time before traffic: 8 to 15 days depending on weather condition   
  • Recommended thickness: 0.7 to 4 mm  

Recommendation for Use

[Translate to English:]

  • ควรหลีกเลี่ยงการป้ายกาวเหลวใต้แผ่นหลังเป็นจุดๆ (ซาลาเปา) ดังภาพ 1 เนื่องจากจะทำให้มีช่องอากาศระหว่างแผ่นกระเบื้องกับพื้นผิว
  • ควรหลีกเลี่ยงการใช้กาวเหลว เมื่อมีแสงแดดโดยตรง หรือพื้นผิวที่ร้อนจัด
  • การรักษาเส้นยาแนวให้เป็นเส้นตรง ควรใช้พลาสติก เป็นรูปกากบาท (spacer) คั่นระหว่างแผ่นกระเบื้อง (ดังภาพ 2) ขนาดความกว้างของพลาสติกที่ใช้ (กากบาท) คือ ความกว้างของร่องยาแนว
  • เพื่อป้องกันการรั่วซึมของน้ำเข้าใต้แผ่นกระเบื้อง และป้องกันการเสียดสีของแผ่นกระเบื้อง ขณะที่มีการสัญจรบนพื้นผิว ควรเว้นร่องยาแนวอย่างน้อย 1.5 มม. สำหรับงานผนัง และอย่างน้อย 3 ถึง 20 มม. สำหรับงานพื้น
