Welcome to the forums Lisa,The base should be concrete,with only slight fall to gulley,a rapid setting flexible adhesive and flexible grouts...to a stick to the porcelain, and withstand cold and heat.......an impregnator sealer should also be applied to the porcelain.....Gaz
BAL Prime APD
A modified acrylic polymer dispersion for use as a primer for a variety of backgrounds/bases prior to fixing ceramic tiles, mosaics and natural stone and prior to the application of levelling compound and the BAL WP1 TANKING SYSTEM. BAL PRIME APD isolates products containing calcium sulphate such as gypsum plaster and anhydrite screeds from
cement-based adhesives, thus minimising the risk of reaction between the two materials.
Also suitable for use on
cement:sand rendering, blockwork, plasterboard,
cement:sand screeds and timber. It also provides surface strength to friable surfaces and reduces the porosity of porous backgrounds/bases, thus preventing the formation of air bubbles and prolonging the flow time with levelling compounds and extending the open time of
tile adhesives. The primer is blue in colour to help ensure that a complete and even coating is obtained.
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 Superflex Wide Joint Grout
A highly flexible, water and frost-resistant
cement-based powder grout with built-in admixture specially designed for use in areas where increased flexibility and enhanced durability are required. Suitable for grouting tiles with joint widths up to 20mm. Suitable for interior and exterior locations on both wall and floor tiling. Ideal for grouting limited movement areas such as timber floors or heated screeds. Suitable for grouting in swimming pools. Conforms to BS EN 13888, Type C, Class G2.
