The hairline cracks in the Diamond Bright will not cause the pool to leak. You must have got plastered in hot weather and the plaster cured quickly. It is just cosmetic on the surface and not through the entire layer of plaster.

It is not normal for hairline cracks to form in the plaster pool finish in the first few days after application and water fill. However, it does happen and one of the most common reasons is because the pool was filled too slowly. It is important to fill the pool as quickly as possible to prevent this from happening.

you can either use a good epoxy pool paint if you intend refurbishing the whole pool or use an epoxy paste. V out the cracks and fill with epoxy paste.

Yes. Suggest you inspect pool and drain closely for cracks or other damage.

All concrete cracks. So one doesn't have to worry about hairline cracks. If it is an old structure, cracks may develop because of corrosion of reinforcment bars. One should open up the plaster/concrete cover and check for the amount of corrosion. If it is nominal, one can plaster up again with waterproofing chemical. If the corrosion is more, there are methods of strengthening a beam. One should have this beam inspected by a structural engineer. If such hairline cracks have developed along with excessive deflection at the mid-span section of a beam. One should vacate the building and get it strengthened by a structural engineer.

It really depends on the condition of your plaster. Could be from days up to a few weeks.

Concrete cracks. You can do everything right and use the best materials, it will still have hairline cracks. It's normal.

Very tiny cracks in the finish may be due to the material shrinking when it dries and is not neccessarily an indication of a problem. If however the cracks are larger than hairline and longer than a couple of inches it may indicate a more serious problem.

You drain the water then plaster the walls from inside

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.

Some slight crazing, or spider-web cracks, may appear in stressed areas of new plaster, as at corners. Anything larger is suggestive of trouble, wither the structure is shifting or the plaster was incorrectly applied. Manual application of true plaster is not common these days. Plaster board (or sheet rock) may develop thin "cracks" in the filler used to bridge over the edges of the boards. Larger cracks, or located in the middle of the sheets, is suggestive of settling or installation problems.

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.

Yes it will crack. I think any and all concrete will crack. Maybe not enough to leak water but hairline cracks. Coat your pool with good waterproof sealant if leaks start.

Yes, plaster is a noun, a common noun. Plaster is also a verb (plaster, plasters, plastering, plastered). Example uses: Noun: The plaster in the hall is cracked. Verb: We'll have to call someone to plaster those cracks.

Mix it in the plaster like mixing flour and water , only with a dye in the plaster

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.

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.

No, salt does not damage the plaster. Improper water balance will.
