Is it better to resurface a gunite pool with plaster or fiberglass?
My mobile home park is going through this right now, so I will give you what I have learned. A word of caution, I am still trying to find an unbiased answer myself all of my pros/cons come from the fiberglass or plaster contractors so of course they believe their product is better.
From our pool maintenance company (the one unbiased answer I have) They recommend using fiberglass on our Spa to reduce the chance of black algae, and plaster on the pool for the ease of maintenance.
>>Pro's for plaster.
Underwater epoxy repairs can be made without draining the pool.
More resilient than the Gel-Coat of the fiberglass.
More readily available contractors.
>>Pro's for fiberglass.
Resists Black Algae.
Resists rust stains from behind.
Lasts longer than plaster.
---Con's for plaster.
If Black Algae starts its roots go through the pourous plaster and embed in the gunite, and will always return.
Plaster doesn't bond well to old plaster.
---Con's for fiberglass.
Fiberglass companies go out of business because their products fail in a few years.
Fiberglass contractors are hard to find.
The only way to repair fiberglass is to drain the pool and apply a new Gel-Coat over the entire surface.
Fiberglass is not waterproof at all, only the Gel-Coat is.
A Plaster contractor said...
"I have heard that the fiberglass fails in like 5 years and then the company goes out of business."
A Fiberglass contractor said...
"I have heard of huge sections of the plaster falling off, because the old layer of plaster was not completely removed and when it came off it took the new plaster with it, in court the contractor's stance was that their coat held on fine and that it was not their fault since their work was still sticking to the old plaster."
I wish a neurtral party like a university would do a study on this.
Just as lost in the sauce as the original poster.
Hum, not sure if you can actually plaster a fiberglass pool. The glass would have to be removed first. You will have to consult a pool builder, a company that installs fiberglass shells or a company that installs fiberglass in plastered pools - thus converting a gunite/plaster pool into a gunite/fiberglass pool. The later uses the old pool shell as the sub-grade or foundation so to speak. k
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…
How to resurface a gunite (or concrete) pool with fiberglass is explained in "Pool Resurfacing Made Easy" written in 1999 by Bill Nash, CEO of UGlassIt Pool Resurfacing, Inc. It can be ordered online at uglassit.com/order_book.htm. The company provides all the material and supplies necessary for the resurfacing of all kinds of swimming pools, plus telephone help is available 7 days weekly.
If your pool is made of both fiberglass and cement or gunite and the sides are fiberglass but the bottom is either cement or gunite is this a fiberglass pool that was filled with cement?
No. An older (possibly better) type of Fiberglass pool was constructed in this manner, with a concrete/Gunnite/Marcite trowled bottom and Fiberglass panels at the side of the pool. Panels are caulked together along vertical joints. Actually not a bad deal, but caulked joints must be maintained. Once the concrete starts showing through at the bottom of the pool, its time to drain and resurface. Bottom of pool should be acid washed every 3-5 years to…
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.
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…
By Gunite I assume that you were told you have a gunite pool, The gunite part is the foundation of the pool and does not require watering. The surface which is plaster over the top of the gunite needs water. If you just had your pool replastered in the last couple of days it is critical to fill it with water so the plaster can dry. If your plaster is older and been under water…
gunite is a type of sprayed sand cement used for the bottoms and sides of pools then fiberglass panels are fitted in to form the complete side to the top Fiberglass pools are also produced as complete pools and shipped to site by truck. the obvious difference here is that one pool is made from reinforced cement "Gunite", reinforced concrete, "shotcrete" and reinforced fiberglass and all kinds of systems in between.
Why is the plaster on a gunite pool gray in the middle and white on the gunite side and white on the outside?
The finish plaster is normally white all the way through. It sounds like you are dealing with a pool that has been replastered by the method of putting a "brown coat"/"scratch coat" (the gray plaster you noted) over the original finish plaster surface, and a new finish coat of white plaster on top of that. The scratch coat more like a thin concrete than plaster (doesn't have the white marble dust in it) and is…
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…
I general, the answer is yes. It the crack comes from the pool moving, and the gunite has cracked, then the gunite has to be repaired before the plaster. Sometimes opening up the gunite crack and refilling with concrete will answer the problem. If movement of the soil is the problem then that has to be fixed first.The soil getting excessivly wet and dry can mean that the pool will move, if it is only…
Advantages of fiberglass versus gunite(concrete) There are many things such as lifetime structure warranty, very low maintenance, cheaper heating costs, and they can be moved. Disadvantages would be depth, size, and finish colors even though there are many colors available for fiberglass pools. Viking Fiberglass pools are the most expensive but you know the saying you get what you pay for. In the northeast you have more of a chance of having a fiberglass pool…
