(5) PATCH REPAIR LESS THAN 8 INCHES
(a) Trim any ragged edges.
(b) Lay an un-shrunk piece of material over the hole and trace the outline of the
patch with a #2 pencil. Make sure to allow for enough overlap as explained
earlier. Note that square or rectangular patches are preferable. Cut out the patch
with pinking shears.
(c) Mask off the area outside the patch leaving an extra half-inch or so of working
room around the contour of the patch.
(d) Peal the polyurethane paint off and clean all the coatings inside the masked area
with MEK down to the bare fabric.
(e) Glue the patch to the old fabric with Poly-Tak and allow it to dry.
(f) With an iron set to 225ºF, smooth the glued areas.
(g) Heat-shrink the area of the patch over the hole with a 350ºF iron. This acts as a
shrinking panel to re-tighten the fabric in the area of the repair. Use a piece of
cardboard as a shield to keep the iron off the glued areas, if needed.
(h) Poly-Brush requires two applications. Each application consists of 2 coats.
The first coat should be brushed on to penetrate the fabric.
After the first coat has flashed off, apply the second coat by brushing or
spraying on then allow it to dry.
If finishing tapes are needed, attach them with Poly-Brush.
Smooth the finish tapes with a hot iron.
Make a second application of Poly-Brush (2 coats) allowing it to flash off in
between coats. The Poly-Brush may all be brushed on if it is a small patch or
sprayed if it is larger or in a high visibility area.
(i) Make 2 applications of Poly-Spray.
(j) For the first application;
Blow and tack off the covering to be sure it is as dust free as possible.
Spray or brush the first coat of Poly-Spray. Allow to dry for approximately 15
minutes
Spray or brush the second coat of Poly-Spray and make sure it is dry before
sanding.
(k) For the second application;
