Yes, fiberglass pools have a smooth finish. Where a concrete pool was a pourus and rougher finish that gives alge something to grab on to. Also staining it. A low calcium level can pit a concrete pool, not a fiberglass, plus a fiberglass pool is more flexible,so ground movement wont crack it. In the long run the extra money you pay for fiberglass is worth it.
A fiberglass pool requires less maintenance, less repairs structurally in the future, is quick to install, and is good for smaller pools. Gunite pools are better for a pool deeper than 8 feet, custom shapes, and is a bit harder on the feet than a fiberglass pool.
u can NOT convert one into another.... ud have to rip it out and start over... either gunite or fiberglass
Both pools have many features Both fiberglass and gunite swimming pools can have almost all the same custom accessories and great equipment. You can design any size or shape gunite pool shell and customize the surface to almost any color quite easily. A fiberglass pool shell manufacturer is like a boat dealer with a catalog of models produced and custom sizes are generally not available. A fiberglass pool can be installed a bit faster than a gunite pool but the major investment you will make in either project usually never warrants a decision based on a few weeks time built sooner. Your gunite pool can have a built in hot tub or water feature , but your fiberglass pool can also. You have more options with coping on a gunite pool than fiberglass, but your fiberglass pool can still be made to look like a gunite pool if you like. A fiberglass pool shell can have a lifetime warranty for factory defects and most gunite builders also offer a similar warranty, I always say though when is the last time you saw a defective bag of concrete or tub of fiberglass resin? The surfaces of both pools can be as diverse as the pools themselves, you can go with white polyester gel coat on fiberglass or white marcite on gunite, your choice can be a custom quartz finish with a fiberglass pool or a custom quartz finish with a gunite shell also, with each pool shell having a respective warranty for finish from as little as one year to as many as 10 full years or more. Both finishes are very dependent on your skills as a pool-owner to manage them, all information you learned when you bought your pool from a licensed , insured swimming pool professional. Fiberglass pool shells rarely get deeper than 8 foot the minimum standard for a diving pool, while a custom shell with gunite can be built to exceed many standards. The old myths of falty fiberglass and gunite swimming pools have been propagated by dealers long since gone out of business. If your looking for a reliable and safe pool that keeps its value backed by strong dealer sales and service networks fiberglass and gunite are equally great choices and readily available. It's never been a better time to be in the circle of pool ownership. getapool.com good swimming
I am researching the same question and this is what I have found so far: having a "freeze line" is not a good condition for fiberglass pools. Fiberglass pools are cheaper to install and use less chemicals to maintain. I was told the chemicals also do less damage to fiberglass, if any?, than to gunite pools. Fiberglass pools must be filled at all times to avoid "popping up". The only thing that still has me leaning towards gunite is a custom pool shape we have in mind. Hope this helps. I am also trying to decide between fibergalss and gunite. I have been told (by a gunite dealer) that there is a problem with staining in fiberglass pools. Besides a low water level, what else might cause a fiberglass pool to pop up?
Gunite will generally last longer than fibreglass (if you take care of the plaster, and "cure" the gunite properly when it is installed). You can also make a Gunite pool any shape and size that you like, whereas you're limited to the few molds that a fibreglass manufacturer has. Personally, I like the feel of a plaster (gunite) pool on my feet *much* better than paint or fibreglass. The biggest advantage of concrete over fiberglass is the structure. 8in. of concrete and steel versus 3/4 to1in. of fiberglass. I'll take concrete and steel every time. 30 yrs. in the biz. tell me so.
Although the maintenance and cost of construction is higher than of fiberglass, it will hold up probably years longer than fiberglass. Especially if you will be having kids around- they can be tough on things, and fiberglass can get expensive if you end up with enough scratches, etc.
yes they are easier to install and last much longer!
No, because fiberglass can make you slip unlike concrete steps
This very subject has been debated for years. I can tell with full confidence, that gunite is much better than shotcrete. Both are good depending on the builder.. I can tell you with full confidence, having worked for more than thirty years with both gunite and shotcrete that shotcrete is far superior to gunite. Shotcrete will test out stronger, to much room for human error with gunite.
In my opinion, none! Stick with Marcite. I completely disagree. With 19 years experience in the restoration of older swimming pools, I have learned that fiberglass swimming pools are the best of the best. My business is limited to older pools, so my expertise is in swimming pool longevity, therefor my answer is: If you expect to own the pool for more than 15 years, and if you can afford a gunite, concrete, or fiberglass pool, you should definitely choose fiberglass. On the other hand, if price is the issue, you should choose a vinyl liner pool which will cost about half that of gunite, concrete, or fiberglass. Unfortunately, when you decide to sell, a vinyl liner pool will actually detract from the value of the home. On a geographical basis, Florida is a great place for a fiberglass swimming pool, but so are the rest of the Continental United States. Location does not matter, regardless of what you may read in these forums. The only thing that does matter is that you never empty the pool without professional assistance. The same rule applies to vinyl liner pools. The only advantage to gunite and concrete pools is that you can usually get away with emptying the pool without help. But even concrete and gunite pools can be seriously damaged if the pool is emptied without consideration for hydrostatic pressure. Just like construction of a gunite, concrete, or vinyl liner pool is quite important, so is the installation of a fiberglass pool. It is not a DIY project for most people. Another important factor with fiberglass is the manufacturer of the pool. I consider the very best to be San Juan pools because no San Juan pool owner has ever contacted our company for restoration before the pool was at least 27 years old. Finally, there is no such thing as a surface that will last a "lifetime", unless you consider a lifetime to be 20 years or less (excluding only San Juan). Frankly, I thought 20 years was a "generation", but the pool manufacturer's and builders seem to have the two terms confused. Fiberglass requires considerably less chemicals and far less maintenance that any other pool currently in existence.
there is a product called "pebble tec" that is great. better than both products you mentioned. it is a little more expensive, but looks and lasts much better. other wise i would stay with plaster. from what i understand it adhears better to the gunite.
Fiberglass insulation is better than air, but closed cell foam is better.
