This factor allows the builder to coat the fastener with a thin film of mold release before bonding to permit easy fastener removal after the epoxy cures. Fatigue tests of bonded threaded rods with and without a thin coating of mold release show only a 4-10% reduction in the overall fatigue strength of the fastener with mold release. A thin film mold release will yield a more predictable performance than a thick film. Mold release may include paste wax, non-stick cooking spray, silicone spray or hair spray. While the reduction in strength of the fastener treated with mold release is slight,typical deck plans for roof baltimore city it should be taken into account when calculating hardware loads. We recommend adhesive bonding to all hardware and fasteners rather than the use of mold release whenever possible.

6.6 Removing bonded hardware Occasionally it is necessary to remove bonded hardware items. At temperatures above 150��F (66��C), cured epoxy begins to lose its physical properties; the resin softens and its bonding capacity is reduced considerably. You can use this characteristic to your advantage when you would like to remove a piece of bonded hardware. 1. Remove all fasteners. If you used a release agent on them when you bonded the piece in place, they should come loose without too much difficulty. If the fasteners were bonded in, it will be necessary to apply heat to them, using a soldering iron. The epoxy around the fastener will soften enough to loosen the fastener when enough heat is conducted down the fastener. 2. Heat the fitting briefly with a propane torch. garden deck decoration materials screeningProtect the area around the fitting from heat damage by covering with water-soaked plywood. Allow the heat to conduct through the base of the hardware. A sharp rap with a mallet should be enough to dislodge the hardware. If the fitting doesn't break loose easily the first time, don't force it. Heat it a second time with the torch and try again. 3. Replace the hardware by following the procedures in Section 6.2. Re-drill the fastener holes in the existing epoxy as you would for a new installation.

It attacks in two ways: heat and ultraviolet (UV) rays. wood decks for a mobile homeAny epoxy finishes without protective coatings are vulnerable to rapid ultraviolet degradation. WEST SYSTEM?Brand epoxy, including the 207 Special Hardener?, is not intended to be used as a final finish. Therefore, you should cover bare epoxy that will be exposed to direct sunlight as soon as possible with an opaque paint or a clear coating (varnish). If the surface is to be painted, add pigment to the last two coats of epoxy to protect the surface.
