What we are about to show you are the facts about toxic fiberglass products and why Epoxy is becoming so popular today.

First of all Polyester and Vinyl ester resins are ½ the strength of epoxy and secondly they do not hold water or can contain a liquid.

Example: If you rolled or sprayed polyester or vinyl ester resin on a surface of concrete, steel or any substrate, it would not hold water. It dries outward and under a microscope has small holes. Even when you use polyester or vinyl ester with a fiberglass matting it still will not hold water. You must apply a gel coat to contain the water. This is a well known fact to the boat builders of today. All gel coats made today are not warranted by the manufacture for more then 1 year. This is why most 1 piece fiberglass pools and yachts are only warranted for 1 year on the outer coating.

If you roll out an epoxy resin it will bond to concrete and steel and will film and dry from the top down causing the material to be non-porous. Under a microscope there are no small hydration holes therefore each and every coat of epoxy not only bonds to the material it is being applied to but is also watertight Standard fiberglass has been outlawed today for any use for food, drinking water, biological, and aquariums. The EPA and OSHA have found that polyesters, vinyl esters and gel coats continue to give off toxic fumes and eventually break down in many cases. Therefore all external and internal coatings must be a certified NSF product. NSF or ANSI products are all epoxies. The Federal Government must certify these products. Examples of problems with polyesters to vinyl esters and gel coats: In 1979 the biological tanks at a college were coated with a polyester resin which the substrate was made of concrete. While the material was being applied the fumes were so bad all the students had to leave the building and the fire department was called. The

EPA shut down the job and made them ventilate the building. The fiberglass and gel coat deteriorated in less then 60 days killing all the fish in the tank.

Some people have complained of the toxic fumes from the polyester as far away as ½ mile from Swimming Pools being resurfaced in their neighborhood. These fumes have been known to set off pace makers and cause Asthma attacks. (Polyester & Vinyl esters increase the heart rate and to some can shut the lungs down. What we are showing you is that polyester, vinyl esters and gel coats were good for the old days but they are pretty much prehistoric today. They do not and cannot compare to the new epoxies available today. Some companies still using the old systems of fiberglass will never change and their generation will usually not educate themselves about the new world and new products available. After doing some research we have found that most of these companies using the old systems are usually not members of any composite or polymer associations or do not take any seminars or courses to better educate themselves. They will eventually be like the dinosaurs and will slowly fade away. Hopefully, for all of us, they will take these toxic prehistoric products with them.

Are concrete or steel walls better for an inground swimming pool?

Steel walls are currently the lowest quality wall for a swimming pool, with the exception of Cyprus wood (if still available). Concrete (not gunite) is superior to any other wall, but a pool with concrete walls generally also has a concrete bottom. In other words, it is a concrete swimming pool. The most popular wall today for vinyl liner pools is fiberglass and, with the possible exception of concrete, is the best possible choice.

Why is your new pool rough on all surfaces?

What type of surface is it? Concrete, Vinyl or fiberglass? If you have a vinyl or fiberglass pool and it is rough it is probably calcium that has precipitated out of the water you will need to have your pool water analyzed by a professional swimming pool company. If your pool is concrete it could be calcium also or it could be an etching of the concrete both are related to water chemistry and the same professional analysis would need to be performed to resolve the issue.

Can you insulate a swimming pool?

Gunite and concrete pools can be insulated by resurfacing with fiberglass. Because fiberglass is non-porous, heat is not lost through the plaster finish. If the pool is already fiberglass, there is nothing further that can be done, unless the pool is not yet installed in which case a spray of insulating material can be given to the outside of the fibreglass pool prior to installation.

What are the disadvantages of fibreglass?

If you're in the market for a pool, you've probably heard a lot of good things about fiberglass swimming pools. Before you buy one, you should be aware of the disadvantages of these pools.Emptying-- One of the first disadvantages of fiberglass swimming pools is that emptying it can cause problems. These pools have to be filled with water at all times to keep pressure on the walls if you want to avoid damaging the pool. If you empty it improperly, ground pressure will cause the fiberglass swimming pool to crack or buckle. If you need the pool to be drained, a professional has to do it to prevent damage.Location-- Another disadvantage of fiberglass swimming pools is that you need to live in a suitable location. These pools are manufactured then brought to your home on the back of a large truck. You have to make sure your property will allow a big truck or crane to bring the pool to your home.Customization-- One of the biggest problems with fiberglass swimming pools is the lack of options. They are prefabricated in different shapes, colors, and sizes. Unfortunately, it is not possible to customize them, so you have to choose from existing models. You are also limited in the size and form that you choose. It has to be small enough to be transported on the back of a truck, so you usually can't get a fiberglass swimming pool that is wider than 14 feet.Sand-- One of the final disadvantages of fiberglass swimming pools is the sand. The pools are usually installed over a bed of sand. The problem with this is that the sand has a tendency to shift after a couple of years. When this happens, the pool will need to be reset.

Where would one buy a fiberglass swimming pool?

A fiberglass swimming pool can be purchased from specific retailers that deal entirely in swimming pools.

However, online sites such as Water World Pools, or All-In-One Pools, do sell and ship fiberglass pools.

Can you drain a fiberglass in ground swimming pool?

No!!! Under no circumstances should you drain a fiberglass in-ground pool. Unlike the standard in-ground pool, the fiberglass pool base is unreinforced concrete or other hard surface material that was applied directly to the soil in a thin layer. It is only there to allow the fiberglass to be sprayed on and form a hard shell. The weight of the water is what holds the fiberglass in place. If you drain the pool without refilling it immediately, you will allow external ground pressures and/or ground water to buckle the sides or bottom and you will have the fiberglass completely redone.
