Applying the Patch
1.
Apply the Dura-Seal glue to the patch and damaged area. Wait 30 minutes (at 75 deg. F or 22 deg.
C) for some of the solvent to evaporate from the glue. The glue should become thicker but still be
quite wet. If it has been allowed to dry too long, give both sides another thin coat. If the glue has
dried too long, it will be difficult to avoid entrapping air bubbles in the bonded joint.
2.
Place the patch and roll it down with the
roller. Place the centre of the patch down
first, then roll it out towards the edges with
the roller. This expels trapped air. Once the
patch is rolled down, do not let it lift up. This
will prevent air from getting under the patch
which causes a weak bond.
3.
If the item is sloped during the repair, tape the patch in place while holding it down. This stops the
patch from sliding away from the damaged area.
4.
Weight the patch down. Place a plastic cover sheet over the patch followed by a weight bag for 12
hours at room temperature. The item can then be moved but should not be filled until the glue has
cured for 24 hours. The weight should hold the patch tight against the item while the glue sets.
The plastic cover sheet will prevent the glue from sticking to the weight bag.
5.
If the patch will be subjected to abrasion after 24 hours, paint over the patch with glue. Painting
the patch also provides protection from ultra violet light and weather. Allow the bond to harden
for 24 hours at room temperature before using the item.
