Large Areas

Step 1:

Make necessary substructure repairs.

Step 2:

Sand off all existing texture (40 to 80 grit surface scratch). Mask off area. Make sure border tape is wide enough to allow a 1/2" to 3/4" overlap of the Flex-Mold to lay flat.

Step 3:

Make pattern of area and transfer to back side of Flex-Mold. Cut to shape, making sure to leave 1/2" to 3/4" border.

Step 4:

The background color of the area to be textured must be of like and even color. To achieve this, gel coat should be thinned with Mini-Craft of Florida, Patch Reducer (p/n: 767PB100, 200 or 300) and sprayed on thick enough to give an even color. Let cure thoroughly.

If *surfacing agent is used in your gel coat, it must be removed by sanding, along with solvent wipe, to assure a proper bond with texture coat.

*A surfacing agent is a solution containing paraffin wax. When added to gel coat or polyester resin it will rise to the surface during curing cycle to seal off air. Exposure to air will prevent a complete surface cure. If no surfacing agent is used, the surface will remain slightly tacky in the shade and extremely sticky in the sun. Avoid exposure to sun during next step.
Step 5:

Lay Flex-Mold in place to check fit and again, make sure the overlapping border lays down. Do not exert pressure on any one spot.

Flex-Mold will stick and the **PVA coating will pull off the Flex-Mold. To keep Flex-Mold from sticking, you can temporarily place some wax paper on deck before placement of Flex-Mold.

*The Flex-Mold is coated with green polyvinyl alcohol (PVA), to server as a release agent as well as barrier coat that prevents a chemical reaction that will occur between the Flex-Mold and gel coat, resulting in a distorted pattern.
Step 6:

Secure one edge with tape. Lightly sprinkle back side of Flex-Mold with talcum power for a lubricant. Remove excess.

Step 7:

Prepare gel coat by checking viscosity with a #2 zon cup. *Gel coat should run through in 45 - 50 seconds. Thin with Mini-Craft of Florida Patch Reducer (p/n: 767PB100, 200 or 300). Catalyze gel coat cool enough to allow sufficient cure time to complete procedure.

*the gel coat must be fluid enough to flow into the cavities of the non-skid pattern to avoid air entrapment. Also, thick gel coat makes it difficult to squeegee Flex-Mold down level over a large area.
Step 8:

Hold Flex-Mold up and pour enough gel coat on surface to start a wave in front of Flex-Mold face.

Use a proper tool (squeegee, board, paint roller) to push along behind the Flex-Mold in a manner that will move a wave of gel coat before the face of the Flex-Mold as it is lowered into the wave. Continue process across entire area.

Another method, when practical, is to roll Flex-Mold on a tube and then unroll slowly to push wave of gel coat along..
