![]() We have developed a collection of many sizes, so now we can cover any sized pool. Sometimes a poly tarp can be "pup tented" over the pool with a rope if the pool is small enough. We are willing to tent the pool when it's too hot, and add heaters in the tent when it's too cold outside. On our projects, our specifications state that absolutely NO calcium may be added to the any of our cement products (concrete, mortar, stucco finishes, or plasters). I know the realities of the plaster crews - slam, bam, pay me ma'm! The faster that they can get the plaster to set up, the faster they can finish it, and the faster they can get onto the next project (since most are paid piece work/by the pool x the amount of material). Too much shrinkage can also lead to leaks around the pipe penetrations & fittings (if they were left to be sealed by the plaster crews without using plaster seals or water stop flanges). This calcium is weaker than the surrounding cement, so after it dissolves it may expose aggregate of a different color of finish.Ĭalcium can lead to rapid drying & shrinkage cracks, the development of calcium nodules, splotching of the finish and/or discoloration in colored finishes. If too much calcium is added or if it is not mixed completely, it will result in white streaking. The hoddy (guy mixing the batch) is adding calcium chloride to the batch to accelerate it's set. It dries on the surface & leaves a white haze behind.Ģ. TOO MUCH water in the mix - the water carries the paste to the surface, as it is displaced during troweling. This is usually due to one of two possible factors:ġ. Some cement paste may develop on the surface of the finish. ![]() That way it gets at least 2 good passed at compaction. Since everyone has individual strengths, it is a good idea to have the guys go over each other work. The purpose is to compress the cement into the tightest matrix possible (compaction). The guys troweling the finish should be troweling as hard as they can on the final pass. The suction could cause delamination or wheel track lines to form. No vacuuming or pool sweeps until it's 25 days old. Don't use powdered chlorines until the finish is 3 weeks old. After 3 weeks, start adding CYA and then calcium. ![]() Use bleach to bring the FC to 1ppm after 4 days. Watch the pressure in the filter tank and backwash as needed. Always brush from the shallow to the deep end with the skimmers off but drains on. This exposed the quartz and colored specks. Check the pH and alk, adding muriatic as needed to keep the pH at 7.0. drop the pH to about 7.0 +/- 0.2, bush 2x a day for a 4 to 6 days, then 1X a day for the next 3 weeks. all contribute.įor most Diamond Brite finishes, after application, fill it with water, run the filter 24/7. Different batches combined at slightly different ratios, slight differences in mix water volume, mixing times, mix to application times, temp of the day, etc. Re: still unable to get rid of some white spots on diamond b ![]()
