Hi All,
Just looking for a bit of advice. I am making a small wetroom/shower on the first floor of my house. I have ripped up the old floorboards in the area and fixed 3/4" ply directly to the joists and noggins at 80mm intervals. I have sealed this with a PVA bond and water mix. I have then glued thin shims to the ply to create a slight fall towards the central drain point. I have fitted Aquapanel to this and screwed it down. My question is, which type of adhesive should i use to fit tiles to the Aquapanel. I guess i still need some kind of flexibility since i can't guarantee that the floor will not move, but i also need complete waterprooing and good adhesion to the Aquapanel. Products like Unibond tile on wooden floors offers flexability, reasonable waterproofing, but i don't know if it will bond to Aquapanel. On the other hand, the unibond tile on concrete floors will probbably stick pretty well to the Aquapanel, but i guess there is a possibility of it cracking???

Thanks for your time,


Tim

I would now tank out the room with Bal tanking system. I would use a flexible slow set white adhesive, Bal is very good, as is Mapei. I wouls also use flexi grout and finish off by sealing with silicone.

hi tim..welcome mate...
i would use a rapid setting flexible tile adhesive , like bal rapid set flexi and then grout with bal wide joint grout with GT1 admix..

BAL Rapidset Flexible

A flexible, rapid-setting, non-slip, water-resistant and frost-resistant wall and floor tile adhesive especially suitable for fixing tiles, including fully vitrified and porcelain tiles to low porosity backgrounds and bases. Suitable for use on concrete/brick/block walling, cement:sand rendering, plaster, plasterboard, cement sheets, tile backer boards, concrete bases, cement:sand screeds, plywood overlay, ceramic/quarry tile/terrazzo/hard natural stone, vinyl tiles/sheet, mastic asphalt. BAL Rapidset Flexible white is especially ideal for fixing natural stone, slate, marble (including translucent marble) and travertine. Conforms to BS EN 12004, Type C, Class 2FT.

BAL Wide Joint Grout

A water-resistant, frost-resistant cement-based powder grout designed for grouting ceramic floor tiles, mosaics, quarries etc. Also suitable for use on walls. Not recommended for soft glazed wall tiles, or tiles with metal decor or lustre. Suitable for use in interior and exterior locations in both wet and dry conditions. Suitable for swimming pools. Conforms to BS EN 13888, Type C, Class G1.

NOTE: The physical properties of BAL WIDE JOINT GROUT can be enhanced by the addition of BAL ADMIX GT1. The polymer admixture imparts flexibility, increases adhesion and reduces the water permeability thus widening the application possibilities of the grout, with a classification of BS EN 13888, Type C, Class G2.

BAL Admix GT1

A polymer additive for BAL cement-based grouts. Not for use with adhesives. The addition of BAL ADMIX GT1 greatly improves the physical properties and characteristics of the grout.

• Increased mechanical strength.
• Increased flexural strength and flexibility.
• Reduced water permeability.
