(1) Terminate the crack or damaged area by routing out the area using the rotary grinder, just exposing the fiberglass, in a “V” manor leaving a 30 to 45 degree angle on the edges. Be sure to grind past the end of the crack at least ¼” to be sure the crack will not travel.

(2) Remove all loose fragments from the edge of the prepared area by sanding with 100 grit wet or dry sandpaper. Try to keep sanding areas to a minimum. Throughout the process minimized sanding will keep the repair small.

(3) Clean the prepared area with a soft cloth or paper towel with acetone on it.

(4) ACRYLIC FILLER, GRANITE FILLER
& TEXTURING RESIN PREPARATION
With components at room temperature, dispense desired amount of component “A” into plastic graduated mixing cup. Add 30 drops of component “B” per each ½ oz. of “A”. Mix thoroughly with wooden stirrer. If smaller amounts are desired (for example: use 15 drops of component “B” per ¼ oz. of component “A”). Mix each resin and filler in stages (for example allowing acrylic filler to cure before applying granite-filling stage). Used mixed filler promptly as pot life is approximately 15 minutes. “Maintain proper ingredient ratios for best results.”

(1) fill the damaged area to slightly below level with the prepared acrylic filler. To accelerate the cure time, use gentle continuous heat with the heat gun around the edge of the acrylic surface and not directly on the fill to start the cure. Allow 5-10 minutes curing time.

(2) Once cured grind any excess over fill of white acrylic filler to avoid any bleed-through around the edges and allowing cavity about 40 to 50 mils deep.

(3) Over fill with the prepared granite filler slightly above level (accelerate with heat if necessary).

Allow to cure 20 to 30 minutes. (4) Once cured grind the granite filled area to shape and or level using the drill with the 3M Roloc set up as a grinder (use low rpm’s to keep acrylic from melting).

Sand with 100, 200 and 320 grit sandpaper to remove most of the roughness and grinding marks. (5) Apply the prepared texturing resin by dabbing small amounts with the supplied resin brush to recreate the texture look (this may take a little practice on a separate surface to get the desired look).

Allow to cure 20 to 30 minutes. Once cured and if final texture is too rough, sand slightly with 600 or 400 grit sandpaper and buff to achieve desired smoothness.
