Bostik AP 250 Flexibond: Primer, Sealer & Flexible Admixture

Are you tired of dealing with tile adhesives and grouts that just can't handle minor movements or vibrations? Do you need a solution that enhances adhesion, flexibility, and tensile strength? Look no further! At Tile Fix Direct, we are excited to introduce Bostik AP 250 Flexibond, your go-to product for superior tiling performance.

Why Choose Bostik AP 250 Flexibond?

Bostik AP 250 Flexibond is not just another additive; it's a game-changer for both professional tilers and DIY enthusiasts. Here are some compelling reasons why you should consider adding this versatile product to your toolkit:

  1. Improves Flexibility and Tensile Strength
    • Bostik AP 250 Flexibond significantly enhances the flexibility and tensile strength of your tile adhesives and grouts. This means better performance and durability, especially in areas prone to minor movements and vibrations.
  2. Resistant to Minor Movements and Vibrations
    • Whether it's a high-traffic area or a surface exposed to varying conditions, Bostik AP 250 Flexibond ensures that your tiles stay in place, reducing the risk of cracks and detachments.
  3. Meets S1 Classification
    • This product improves the deformability of C2 adhesives, allowing them to meet the S1 classification according to EN12022. This makes it ideal for demanding applications where flexibility is key.

Versatile Uses

Bostik AP 250 Flexibond is an acrylic dispersion polymer designed for multiple applications:

  • Flexible Admixture: Use it with cement-based tile adhesives and grouts to enhance their properties.
  • Primer/Sealer: It's also perfect as a primer or sealer for ready-mixed tile adhesives and floor underlayment screeds.

Superior Performance

The addition of Bostik AP 250 Flexibond to your adhesives or grouts brings several benefits:

  • Enhanced Adhesion: Ideal for fixing tiles to non-porous substrates, ensuring a strong and durable bond.
  • Reduced Permeability: The polymer partially fills cement pores, reducing permeability and preventing damage caused by liquid transfer.
  • Improved Deformability: Makes non-polymer modified adhesives or grouts suitable for surfaces prone to minor movements and vibrations.

Easy Application and Coverage

Applying Bostik AP 250 Flexibond is straightforward:

  • Application Temperature: +5°C to +25°C
  • Service Temperature: Up to 40°C
  • Mix Ratio: 1 part AP 250 Flexibond to 2 parts water by volume when used as a flexible additive and as a primer

Coverage:

  • As a diluted primer, 2.5 litres will cover approximately 75m².
  • Approximately 2.5 litres of diluted AP 250 Flexibond per 20kg of adhesive.
  • Approximately 0.5 litres of diluted AP 250 Flexibond per 5kg of grout.

How to Use

IMPORTANT: Before using Bostik AP 250 Flexibond refer to the relevant Health & Safety Data Sheet, available at www.bostik.co.uk. Tiling and grouting should be carried out in accordance with the relevant British Standards Codes of Practice.

Mixing:

1. Mix 1 part Bostik AP 250 Flexibond to 2 parts water by volume. 

2. Add the selected Bostik cementitious tile adhesive to the diluted Bostik Flexibond, mixing well to obtain a slump free, workable consistency. 

Priming / Sealing: 

3. Do not apply neat, as skinning may occur which may cause delamination. Apply to substrate using a brush. If the surface is still absorbent, apply a second coat. Dries in approximately 1 hour. 

Tiling: 

4. Ensure that all surfaces are clean, dry, sound and free from dust, grease or any contaminating barrier. Make good any unsound areas and remove flaky or peeling layers before tiling. 

Grouting: 

5. Ensure that tiles are firmly fixed and adhesive is completely set. Bostik standard set adhesives should normally be left for at least 24 hours before grouting. Bostik rapid setting adhesives should be left for at least 3 to 4 hours, however these times will be increased with sealed or impervious substrates or at low ambient temperatures, or high humidity. Ensure tiles and joints are clean, dry, sound and free from dust, grease or any contamination.

Application:

6. Apply the Bostik adhesive and grouts modified with Bostik AP 250 Flexibond in the same way as when they are mixed only with water. 

7. Surplus material should be cleaned from surfaces before it dries using a damp cloth. 

8. The addition of Bostik AP 250 Flexibond may slightly alter the working and setting times of the Bostik cement based tile adhesives. 

9. To ensure uniform grout colour the same mix proportions must be used throughout an installation. 

Cleaning:

10. Follow the adhesive or grout product’s cleaning recommendations. 

11. Clean tools and equipment immediately after use with water.
