Where subfloor conditions and building regulations permit, tretford can be cemented directly to the floor.

tretford can also be installed by the double-glue method. (Glue pad to floor surface and glue tretford to pad).

A third acceptable option would be to install tretford over low-profile padding by wall-to-wall tackless- strip method with the following cautions:

1) Use shortest pin-tack available.
2) Mount tack strips as close as possible to wall line.
3) Since unitary backing will not stretch, use knee-kicker to position tretford only.

Padding should be flat and of minimal thickness. Ripple padding is not recommended.

Seaming can be done by conventional tape seam or hot melt method.
