You drain the water then plaster the walls from inside
There is never a reason to paint new plaster in a pool. If you keep your pool water properly balanced, brush your steps and walls weekly, your plaster will last 10-15 years and never need painting or acid washing.
Use a pumice stone. Get it at a pool supply store. It soft, so you may need several.
I am refurbishing a 30+ year old pool. I was told by two pool companies that after the final plaster coat the pool has to be brushed for 3 days to get rid of all the rough and loose plaster, then they re-filter the water, also that if I am going to use the pool heater I cannot turn it on for 3 weeks after everything is done and the pool is refilled.
Let all the water out. Use any type of baking soda and scrub the walls. Then, remove the baking soda by washing down the walls with water.
The japanese put white plaster on the walls because it is fireproof
From possibly to somewhat.
That depends on the type of algae. Restate your question on the specific type of algae you have and include the construction category of the pool ( plaster, vinyl, fiberglass). k
does it cover repairing plaster walls and repainting and fixng plumbing
When was the replaster job done? Were there leaks before the "first" plaster job? Were those leaks determined to be in the walls of the pool or in the plumbing? To answer your question - most likely - yes. Hmm, what do you mean by several? Ken
Typically two layers of plaster are put on a swimming pool. The plaster needs to have a thickness of at least three-eighths inches, which would be two layers of plaster.
The rough buildup on your pool walls are most likely calcium carbonate. Similar to stalactites and stalagmites in caves build in or on pool surfaces because there is a lack of chemical balance in the water. Your pH is running constantly at or above 8.0 pH. The only way to remove them now is to drain and acid wash and/or sand the pool surface. You are likely, too, to not be able to remove them completely but you will be able to control them with vigilant monitoring of your water chemistry. k
Calcium chloride increases the hardness of water. Proper hardness is critical to balancing the water in a pool. Proper hardness is especially important in a plaster pool to prevent leaching of the plaster finish, which results in a rough surface. Calcium chloride can be purchased at home improvement stores at significant savings over pool supply outlets.
Depending on what the plaster surface damage is to the pool, it really is pretty easy to repair the plaster on your pool. You just need a chisel, or a small angle grinder if you are really handy, a hammer, a trowel, some water and a sponge. they sell pool patch kits for all the pool surfaces. look for pool plaster patch kits and you will find an easy to use solution.
Mix it in the plaster like mixing flour and water , only with a dye in the plaster
Replaster the pool and keep the water chemically balanced (PH, alkalinity level etc..) this will keep the plaster from pitting thus keeping it smooth for a longer life.
It makes very little difference
Allowing the plaster finish to become dry will cause blistering and failure of the plaster. If you do not see visual signs of damage, get into the pool and tap on the walls lightly and listen for hollow sounds. You may or may not get any but after filling the pool the change will take place and the blisters will get larger and start decaying rapidly and in extreme cases will totally delaminate. No preventative measures here other than keeping the water in the pool and doing basic service by far this is the least expensive way of keeping the plaster and pool intact. Ken
Break out the old plaster and plaster over the area to seal the plaster surface. It is best to lower water level in the pool first but there are patch materials that work under water.
1. Steel walls will allow for expansion and contraction in temperature changes. 2. Concrete walls are more likely to have rough edges that may, in time, wear holes or cause tears in the liner. Umm...concrete wall pools don't usually have liners. You either plaster the pool then paint over the plaster, or tile the inside. A steel wall pool (although you should get a polymer wall pool instead--steel will rust in a below-ground application even though it's galvanized; polymer can't rust) is less expensive than a concrete pool Steel-wall and polymer-wall pools are less expensive to install. A concrete pool is made from Gunite--a sprayed-on concrete. Liner pools come as panels on pallets, and you bolt the panels together.
Household bleach should not be used to clean pool plaster, and may cause harm. However, using commercial strength bleach or an acid wash will not harm the pool plaster.
Drain your pool, then scrub the walls and floor with pool cleaner.
You could wash your pool walls with pool acid.
Yes,you just need to patch the plaster first.
