Stop adding any chemicals to your pool a week before you plan to drain the pool. make sure you remove as much debris(such as leaves etc) as you can from the water. Also make sure the skimmer basket is in place so nothing gets down in your system. You are not going to use the pool pump as only the bottom drain will be used and will tax the system and draw debris into you pump and pipes. Go to home depot and they sell 110 plug in submersible pumps for around 60$ that attach to a garden hose. You can use the water to water your plants and bushes.place the pump in a bucket with holes in the bottom at yhe deep end of the pool. it will take about 2 days and take out all the way down to 14 inch down at the drain! A pool supply store may rent (maybe even for free) a pump too. Or maybe any rental business. It is very important that when you are emptying any in-ground pool that you empty the " drywell" which may have been installed for your pool. It is preferable to empty the pool quickly and in the case of concrete pools or others, to remove the bottom drain plug to release any water pressure under the pool. Failure to do so where there is under-ground water may cause your pool to lift partially out of the ground. In fiberglass pools this may crack the walls. Ask me- I know. It cost me a $1000.00 to repair.
No, plaster of paris is not strong enough for concrete.
Gunite is covered with plaster. It is sprayed on concrete sorta. They mix it in the hoses and it is blown on. You can go to youtube and see them gunite a pool. I am only aware of plaster, vinyl or painted pool surfaces. The vinyl is just like thin rubber.
Rhinolite gypsum plaster is a combined basecoat and finishing plaster for internal application onto brickwork, concrete blocks, concrete and Rhinoboard. It is also a finishing plaster for sand and cement basecoats. There is some controversy over using Rhinolite in the building community.
its best to contact a local paint retailer about this as he will best understand the application and local suppliers of the necessary materials.
It might stain the plaster. When you have an algae bloom, get on it right away, don't wait. See the link below for more info.
This would be the the excact same price as building a new concrete pool minus some excavation. you would be looking in the 30-to 40k range.
The main components of concrete are calcium silicates. However, it always has a small portion of plaster, in order to slow down the solidification process, so that it does not become solid too soon. As plaster is hydrated calcium sulphate, the answer is YES, concrete has a small portion of sulfur in sulphate form.
Plaster , concrete , marble ,alabaster, any stone that can be sculpted .
Sawn formwork is formwork that for concrete structure that needs to have plaster and paint finish.
Yes you can (re-plaster) There should be a company in your area that does the plaster for pools when they are built and also re-plaster as they get older. Your Pool supplier should be able to suggest who may be the most reliable. yes,
Any pool supply store should be able to help you find coping and plaster. While they may not carry it in the store, they will most likely be able to direct you to a distributor, or set up a delivery for you.
With a masonry chisel. It may be easier to cover it with a new surface.
