Gibco Flex Spot Repairs

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..

Step 9:

Once Flex-Mold is down, start in the middle and push, with a squeegee, excess gel coat out from under Flex-Mold. Squeegee across in all directions. Run hand over surface to feel out any high spots that still need to be squeegeed out. You may use acetone sparingly to wipe back of Flex-Mold clean if you intend to reuse.

Step 10:

Let gel coat cure and peel off Flex-Mold. Remove making from around border. Sand and polish edges using graduated grit. Starting with 100, 220, 320, 500, then compound and polish.

Step 11:

Boat Yard - You can repattern damaged area to look original. Boat Manufacturers - Your dealers can perform cost effective and near perfect warranty repairs. One Off Builders - You can now offer your customer a choice of patterns more attractive and easier to clean than sprayed or rolled on sand grit surface.


We purchase 36" rubber squeegees, fasten a 1/2" x 3/4" board with screws as a stiffener, then cut them to desired length.
