Technical Details and Performance

For strip flooring, trowel onto substrates with the recommended notched trowel (5mm wide by 6mm high V notches at 25mm centres). For parquetry blocks a finer & closer notched trowel is required to avoid excess adhesive; e.g. a 2.4mm wide x 2.4mm high v-notches at 4.8 centre. (Consult “Product Application Information” sheet available from Selleys).
