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.
Hairline Cracks was created in 1990.
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.
It really depends on the condition of your plaster. Could be from days up to a few weeks.
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.
Concrete cracks. You can do everything right and use the best materials, it will still have hairline cracks. It's normal.
From possibly to somewhat.
Moisture under hairline cracks.
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.
