Materials to repair a crack in a polyester pool
The blue Top Coat for swimming pools of Feroca is a type of polyester-based paint.
As Juan Villa comments, it is a polyester of very good quality and density.
It is specially designed for the treatment of finishes on polyester laminates with fiberglass. It has a medium viscosity that allows its application by brush or roller with an estimated yield of 500 grams per square meter
Once applied, it is recommended to let the pool or surface rest before filling it again for at least 7 days.
After that time, a cloth should be soaked in acetone and applied to a small inconspicuous area. If the cloth comes out clean, the pool can be used
The percentage of catalyst F11 recommended by the manufacturer is 1.5%, a lower percentage of cure is not recommended
Polyester resin for laminates and laminates. It is especially liquid. It has low styrene content (DCPD).
This product should always be used in ventilated areas. Also, we suggest having a suitable solvent on hand to touch up imperfections and clean the tools
It is also recommended to have a container at hand to make small mixtures of fiber pool resin and catalyst to prevent it from hardening before it can be applied. Also, it is better not to mix more quantity than can be used.

It is a series of glass threads pressed by means of a soluble emulsion in polyester or epoxy resins for swimming poolsIt is available in 1 square meter, 5 square meters or the largest, 25 square meters.
To avoid the characteristic drawing of this type of fibers and to give a good uniform finish, it is recommended to use a surface veil or mat of 30 grains per square meter.
Perfect for repairing pools with fiberglass finishes. Its purpose is to leave an aesthetic, smooth appearance without roughness or imperfections on the pieces. Ideal to avoid the marking on the surface of the piece of the drawing of other thicker glasses.
Other tools you will need: spatula, brush, sandpaper and solvent...
During the step by step, the expert Juan Villa uses awooden spatula to apply the polyester. Also, in the case of the Blue Top Coat, thicker, he uses a soft brush to apply it on the gap.
The sandpaper is an almost obligatory option. The surface to be repaired should be sanded first to achieve a good adhesion of the products, and later in case there are any flaws or protruding bumps

In this video, the expert Juan Villa explains the step by step of how to repair a pool with blue Top Coat for swimming pools and other materials:
Step by step to repair cracks in swimming pool
Prepare the application surface
Due to chlorine and soaps in swimming pools, it may be that the polyester has a certain layer and little adhesion, explains Juan Villa.
To remove this layer, the surface must be sanded with care not to overdo it. Juan Villa mentions that without this step it would be impossible to have a good adhesion for the rest of the materials.
Repair patch for fiberglass pool
The step-by-step repair begins with the application of a fiberglass patch. This will be made of the same material as the pool, polyester and fiberglass
To do this, two pieces of 300 g mat fiberglass are cut and placed on top of the crack. One of the two will be smaller than the other and will be placed on the outermost part so that the "step" is not so noticeable.
Over these, a tulle, gauze or fiberglass veil will be placed to make the finish smoother, Villa explains.
Catalyzing polyester resin
All polyester resins come with a catalyst. Juan Villa uses Ferpol 100 BSX15 for this step, ideal as a pool resin.
In order to apply the resin correctly, it must be catalyzed at a rate of 1%, 1.5% or 2%, depending on the weather and conditions or whether it is winter or summer
In order to catalyze correctly, the polyester must be weighed. The expert weighs about 50 grams of product, then applies a few drops of F11 catalyst.
Application of the polyester resin and gluing of the glass fiber
After mixing the polyester with the catalyst, it is applied directly to the surface where the fiberglass will be glued to ensure good adhesion
Next, the first piece of fiberglass is placed on top and more polyester is applied on top to close the crack. Then, the second piece is placed on top and the process is repeated.
Finally, the surface and finish fiberglass veil will be placed on top, applying the polyester as in the previous case The function of the veil is to give a great finish to the repair of the crack, in addition to preventing water leaks.
As an advice, Juan Villa highlights the need to use a mask to use these products, specifically to work with polyester resins
After these steps, the polyester and fiberglass should be allowed to polymerize well for at least 1 hour. If the result is not very aesthetic, Villa recommends sanding the surface before the next step.
are you already getting the hang of how to repair cracks in fiberglass? There is one last step left and we are done:
Application of the Top Coat for swimming pools
The next thing to do for a perfect finish is to apply a coat of blue pool top coat
Villa remarks that this step is essential for a good aesthetic result and for the crack repair to seal and not leak water.
To begin this step, it should be done in the same way as it was done with the Ferpol 100 BSX15 pool resin
First, the desired amount of resin is weighed
Next, the F11 catalyst is applied in a similar percentage to that of Ferpol, 1.5%
It is applied carefully with a brush over the desired area. A couple of coats can be applied if necessary.
The texture of the Top Coat is denser than Ferpol, so more care must be taken in the mixing process. Villa also recommends use a soft bristle brush the Top Coat should be applied with a thin layer of a thinner that has not been used before.
Optional is to include a solvent to go over the edges of the gap repair to blend the finish and integrate it with the rest of the pool. Also, you can include a sanding of the final result with a water sandpaper to make it perfect.
