Many, many years. The only place you'd expect to see wear, after say five years might be the steps or areas subject to erosion from water pressure.

You are in the process of building a new pool and you are at the gunite stage they did the gunite 2 weeks ago and you noticed that there is rebar and wire ties showing in the gunite is this bad?

Rebar and or ties exposed in a gunite/shotcrete pool shell is bad but not unrepairable. The exposed steel can rust, and may bleed through the plaster leaving a stain. It may also cause the plaster to delaminate in that area. To remedy the situation the rebar and ties should be cut back or ground out and into the concrete. Hydraulic cement can be used to patch over the areas before the pool is plastered.

Does a gunite pool shell have to be waterproofed before plastering?

A gunite pool shell IS waterproof before plastering. First, gunite/shotcrete is not water proof. The reason for the plaster is to make the pool water proof. You don't have to and should not water proof gunite because it will affect the bonding properties for the plaster. Contrary to the previous answer, Gunite is in fact "waterProof" when correctly applied. Unless there are improperly prep'd cold-joints (the point at which one application has stopped for some reason -perhaps rain, slow truck turnaround, etc- and begun at a later time), a Gunite pool could virtually be "painted", providing a high steel-trowel finish was applied to the Gunite. But, Gunite pops (begins to set and cure) faster than typically appied Marblite or Diamond Bright type cementitious finishes. Actually, the Gunite "finish" surface is purposely left fairly rouch, providing a better surface to which the finish/color material may bond.

What is the freezing water temperature for a gunite pool and at what point do I need to heat the pool to prevent plaster damage?

Plaster pools are pretty robust, and have virtually no issues freezing for short periods of time. If you are in a climate that stays frozen (for more than a day, like Central Florida) then you want to winterize the pool. A quick Google search should yield good answers as to how.

How straight and flat should the new swimming pool gunite be before plastering?

The plaster in the bottom is the thickest and is trolled to be straight. The plasterer is not going to use a transit to see if it is level, it's just going to be what it is. After working a year and seeing the construction of about 160 pools, I've never had a customer call back because the bottom of the pool was not level. I think it is a non-issue. The location of the main drains should be in the deepest part.

How long does the gunite have to cure and how long does the plaster have to cure on a swimming pool?

Most recommendations for gunite are for a cure time of a week. While curing, the gunite should be wet down frequently, this will slow the curing and result in a stronger end product. I'm not familiar with the use of plaster in pool construction, so can't help you there...sorry. As a pool builder, we let our gunite cure for 28 days as that is how long it takes a 12" x 12' bond beam to reach 80% of its strength. For the plaster it depends on what type. Marcite and quartz application are applyed the pool is filled right away. For Pebble finishes, its applyed and then the next day its detailed and then filled. From there it takes a solid month keeping the total disolved solids (TDS) very low while the interior finish gives up moisture and calcium. During that time CYA, Salt and Calcium should stay out of the pool. I would recommend 28 days as well with a drip line that keeps the gunite wet. The whole idea is curing and not drying. For plaster the appropriate method of curing is first to make sure the heater is bypassed and then keep the pH between 6.5 and 7 for the first month while the plaster cures. Brush daily. I would use a quart per 10,000 gallons of a good phosphate based sequestering agent at the initial start up followed by 5 oz per 10,000 gallons each week. Do not add salt or hardness for the first month. Bring pH up after the first month and then bring hardness up after the first two months. Add salt month three if it's salt water.


What is the recipe for plaster coating on a gunite pool sufficient to repair an area measuring 2 square feet and one-half inch depth?

A reputed recipe for pool plaster on a gunite pool is 1 part white cement to 2 parts white (preferably quartz or silica) sand. You should probably also add a bonding agent to the mix to make sure that your new plaster adheres to the old. All of these can be found at pretty much any home repair or hardware store. Mix the dry ingredients first and then make a shallow depression and gradually add water till you have the consistency similar to chunky peanut butter. Add the bonding agent per the instructions on the package and you are ready to go. Good luck!


Is there any way to remove dark spots or 'burn marks' after 30-inch chlorine tablets are left on the bottom of a gunite plaster pool?

The black (burn) marks show up on Gray plaster pools. White plaster pools will show up as a yellow or rust color. Remove the tabs and put them in a proper floating devise, the marks will go away in time. Try using wet and dry sand paper on the burn marks to reduce their visibility and roughened plaster.. additionally, tablets of any size should NEVER be placed or tossed into the pool or skimmer. K

How long should you wait after plastering internal walls before laying wooden floors or hanging doors?

Normally the interior doors are hung before the plaster goes up. Doors attach directly to studs in the walls, so they usually go up before the plaster. With wood floors, they are normally the last thing to be laid - even after the painting.
