Get an instant estimate of how much tile adhesive to buy. Enter your area and trowel notch size, and tell us if you're back-buttering large format tiles.
•Larger notch sizes leave a thicker adhesive bed and use more adhesive per m².
•Back-buttering, applying adhesive to both the tile and the substrate, is recommended for tiles larger than 600mm and roughly increases usage.
•Uneven substrates may need more adhesive to level out, so buy a little extra where possible.
