PROCEDURES

1.  Remove floor covering over broken-up areas.

2.  To help keep dust to a minimum, wet area to be removed with water at approximately 2 gal. (7.57L) per sheet of plywood. Let soak for 10-12 minutes, then remove broken Maxxon Underlayment.

CAUTION: Hammering or pounding out the gypsum product can cause it to lose bond far beyond the broken area.

If dust is not a problem, a circular saw with a masonry blade may be used to cut the perimeter of the underlayment to be removed. Set blade depth 1/32″ (.79 mm) deeper than the gypsum underlayment.

3.  Inspect the plywood, either remove and replace, or reinforce plywood subfloor. Replace plywood if delaminated or if broken plies exist.

Optional: To reinforce, staple or nail galvanized diamond metal lath.

4.  Spray or brush the Floor Primer over the plywood at the rate of 300 ft2 /gal.. (27.87m2/L)

5.  Mix and pour out the gypsum underlayment mix onto the plywood, float or trowel to a smooth surface to meet the existing gypsum underlayment height.

6.  Material should set within a few hours.

7.  The gypsum underlayment must be completely dry before replacing floor goods.
