I have an older cement/plaster pool. It holds water just fine. But there are several leaking cracks at bottom seams; some small areas where cement has worn away; a single ten foot line where cement has cracked slightly bulged in an upper sidewall. The areas are visible (dark) when pool is filled so I have drained want to paint. First, can I successfully repair with hydraulic cement? And, how long to quot;curequot; before painting?
Gail; Hydraulic cement swells as it cures, its exactly what you should use in a concrete pool.
First you may desire to bathe off all the flashing cement - right down to the bare concrete. Then take a diluted combination of muriatic acid and water - brush it into the crack facets with a small brush. Rinse the crack nicely and permit it dry. Now purchase some (waterplug) hydraulic cement. examine online for this via entering into Waterplug interior the google bar. combination this up in accordance to instructions and take a small margin trowel (obtainable at any domicile center) and rigidity the waterplug into the crack. do no longer combination up too plenty because it gadgets up quite speedy. initiate on the backside of the crack and artwork up. permit it dry and your issues would be over. as quickly as you initiate filling the crack, do no longer provide up until you're finished.
Mix a small amount of hydraulic cement according to the directions on the container, then apply it to the crack to seal it up and prevent water from leaking out during the rest of the patching operation. Make sure that the cement goes into the crack itself, and not just over the top to get the best seal.
How To Use Hydraulic Cement
You do not have to have hydraulic cement. Regular Portland cement mixed up as a plaster will work fine. Scrape off any paint so it will adhere better. Hydraulic is use where curing under water is needed. Since your will be dry, it is not needed. There is a product called surwall, spelling may be off, that is good for this. It has fiberglass fibers in it for strength.
