How soon can you swim after plastering pool?
A plaster pool provides years of functional beauty. Thus, it's best to practice pool owner patience before taking a swim in the freshly filled pool. Wait for at least 48 hours for the water to clear. Also, you're better off sticking to the startup procedure to ensure years of durable performance.

NOTE: Typically, swimming can resume 48 hours after the pool has been filled with water.
Chlorine/non-chlorine chemicals – When adding chlorine or non-chlorine chemicals to “shock” your pool after a fill-up, wait about 24 hours or until levels are approximately 5 ppm. If you'll only be adding liquid chlorine, it's generally safe to swim after about 4 hours or until levels are 5 ppm or lower.
Pre-dissolve all chemicals before adding to pool water. Always add chemicals to water, not water to chemicals. Do not add chlorine or other sanitizers for the first 72 hours and not until after you have brought a water sample into the store for testing.

While the rain can harm the chlorination process, it can also create issues with the plastering process too. Rain will cause streaks, discoloration, and curing mistakes once the plastering has begun. Not only will it cause streaking, but it also causes something called hydrostatic holes in the granite and plaster.
A plaster surface, in a properly maintained pool, can last 15 to 25 years. PLASTER IS NON-TOXIC AND ECOLOGICALLY SOUND: There is a lot of concern today about toxic products.
Your first instinct when you fill your pool with new water, is to shock it. But that shock then oxidizes the metals, that chemical reaction then causes the green hue in your water. This is common with refills that used well water or even water that hasn't been shocked but instead contains a high level of metals.
In terms of swimming in a pool that has been recently shocked, you may be exposing yourself to the risk of skin and eye irritation. If this happens then rinse thoroughly with clean water for several minutes (source).
How long does it take plaster to dry? For a freshly plastered wall to be completely dry, it can take 1-2 weeks, sometimes even more.
Does pool plaster change color as curing?
One major thing to remember is that pool plaster can change colors or overall look as it sets and cures. Plaster is hand applied, so it is normal to expect slightly uneven areas, and the color will not be 100% uniform throughout the pool. Also, as the plaster cures, the appearance will change slightly.
New installations and drained pools: A common appearance of cracking can occur when a cementitious interior finish is wetted prior to being filled. Microscopic shrinkage cracks (micro cracks are present in all hardened plaster, precast, shotcrete, and concrete products) absorb water faster than the overall surface.
After the concrete is sprayed on, it needs time to reach its full potential. It doesn't dry, per se. It hardens and strengthens in a long process called curing. For a pool shell, this takes about 28 days.
