If you have a fiberglass swimming pool, and your surface needs a little TLC. You have arrived at the right place. Unfortunately, when you go to resurface a fiberglass pool your options are more limited than that of a concrete pool. In many cases the benefits of a one-piece fiberglass pool make this small trade off well worth it.
You can rule out marcite, plaster, gunite and exposed aggregate. These are all variations of a rather similar product and will not adhear properly to fiberglass.
This leaves you with two options. One is highly less popular than the other and for good reason. It is possible to paint a fiberglass pool with an epoxy paint. It is certainly inexpensive BUT, the main drawback is lifespan. Swimming pool paint can last two or three seasons. It is also something that can be done by a homeowner themselves (however in areas of high groundwater special precautions must be taken to ensure that the swimming pool does not pop out of the ground). Besides the labor costs to do this, once there are several layers of paint on the swimming pool, it would need to be sandblasted to get back to the underlying fiberglass before it could be re-fiberglassed.
Although considerably more expensive than paint, the best resurfacing method for a fiberglass pool is to have the swimming pool re-fiberglassed. This will provide you with the longest lasting surface appropriate for your swimming pool.
There are two types of fiberglass surfacing options. You can opt for a Fiberglass Surfacing System such as ours or what the industry calls a “gel coat.”
A gel coat is the use of just the polymer, without any fiber mixed into it. This will do an okay job of sealing your pool, but the polymer gains much of its strength from the fiber reinforcement. I have seen this on online forums being called “fiberglass paint”. Similar to simply repainting a surface it eventually gets warn down and needs to be done more often.
We provide our customers with a Fiberglass surfacing solution which can be seen here. The difference is the use of the glass fiber matt to reinforce the resin. This adds strength and provides you with an increased product life.
