The swimming pool publication, Service Industry News and its’ PhD chemist, recently peer reviewed the NPC/Cal Poly (NPIRC) Phase 2 pool plaster study report and concluded that white spotting (soft spots, spot etching, and spot alteration) of their plaster pools was not caused by aggressive water, and that the claims (by the NPC) regarding that study are false. In fact, every plaster study of the past twenty-five years has exposed that the NPC is wrong, and that aggressive pool water does not…Continue

If NPC leaders would just acknowledge what improper plastering practices do to pool plaster, there would not be a controversy within the industry - and there would be fewer plaster defects and discolorations occurring.
Case in point: Adding calcium chloride (hardening accelerator) to plaster and water troweling enables pools to be plastered faster and easier. But adding calcium chloride (CC) to a color pigmented plaster can also lead to blotchiness and mottling, which pigment…Continue

Instead of writing a “he said, she said” article about the plaster spotting controversy, Service Industry News (SIN) thought it would better serve the pool industry by conducting their own investigation to determine what information is true, and false. They started on that goal by analyzing the Cal Poly test pool studies. In their July 31, 2015 issue, SIN presented credible evidence (from the Cal Poly Phase 2 report) that the white spotting of the plaster test pools was not caused by…Continue
So I just got a Power Vac PV2100 and filmed it for my YouTube Channel. It is a pretty awesome product and will speed up my time out in the field tremendously.
It seems even in my area the Hammerhead is more popular and was wondering if it was just better marketing or better product that makes this appear so. So a little informal survey. Which do you use and which would you think about purchasing? And has anyone used both and can compare that way?
Here is my blog article on the…Continue
As we know, sales of newly constructed in-ground pools have plummeted in recent years, however there are builders who are thriving in this new environment through various methods which include adding value and differentiating their businesses from competitors.
The explosion in the health and fitness industry works to our advantage. This is something that should be focused on when proposing a new pool to a client. The health benefits of an aquatic work out are considerable. Swimming…Continue

The NPC has drafted a plastering standard which has been submitted to ANSI for approval. But the NPC did not include and address many proper and improper workmanship practices, such as, limiting water content (water-to-cement ratio), calcium chloride additions, and wet (water) troweling. These are all very important issues for the making of quality pool plaster.
And unfortunately, an article by Pool & Spa News about the new proposed plaster standard does not tell the whole story…Continue

I have been testing the Bio-Active CYA reducer and filming the results. Working on a new video in which I am testing it in six pools like the manufacture did for the back of the packaging. I know the stuff is working because the Turbidity test solution is not as cloudy on the follow-up test but getting a spot on CYA reading is tough.
I suspected there was some interference with the results in some test pools and called Taylor Technologies. The Chemist assured me nothing will interfere…Continue

Decades ago, people in the pool industry started becoming aware that there was more to pool maintenance than just adding sanitizers to the water (to kill algae and bacteria) and filtering it (to help keep it crystal clear). Gradually, we learned that even properly sanitized and filtered pool water could become unbalanced.
We figured out that unbalanced water could be either scale-forming, in which case a layer of calcium scale would form everywhere – or…Continue

Are NPC leaders really trying to resolve plaster problems, or will they continue to ignore and/or misrepresent the research studies that have already provided the answers? The NPC says that there has been decades of debate regarding plaster problems. Actually, there have been decades of pool plaster studies, but no honest discussions or debates, and no accountability.
There was a time when NPC leaders understood that improper plaster workmanship can cause plaster defects and…Continue
With a lot of publicity and fanfare, the National Plasterers Council (NPC) recently invited the onBalance group to participate in new test pool studies to determine the cause of plaster spotting, which they claim is caused by aggressive pool water.
The NPC wants the test pools plastered with good workmanship and supervised by onBalance, and then they want the pool water to be maintained aggressive (per LSI) to see if spotting develops on the plaster surface. The NPC says “the testing…Continue
FACT and REALITY
Longstanding cement and concrete science has established that calcium chloride-in acceptable quantities-is a primary cause of discoloration in cementitious surfaces, particularly when steel troweled. Further, the Portland Cement Association research performed in 1966 described that when the ratio of cement alkalis to chlorides was low, a light spotting discoloration on a darker background resulted. The white cement used in swimming pool surfaces is a…Continue

It is understood that muriatic acid can dissolve and etch a plaster surface. Therefore, why, after working hard to achieve a smooth, brand-new, hand-crafted, quartz pool-finish, would anyone immediately perform an “acid wash” on that pool? Yes, that would increase the exposure of the quartz color; but isn’t that shortening the life of the plaster and causing future…Continue

There are proper steps to follow for the making of quality pool plaster, including color, quartz, and pebble finishes. There are also improper practices that can lead to early deterioration and discoloration. Following is a ten-point checklist that will help achieve a smooth, long-lasting, and discoloration-free swimming pool plaster.
1. Plastering in extreme weather conditions can lead to quality and durability problems. The ACI and PCA have specifically warned against…Continue
For as long as I can remember, the pool and spa industry has generally behaved as though pools and spas exist in a vacuum, as if they have little or nothing to do with the surrounding environment.
Fortunately, that’s changed for many forward-thinking builders who have become sensitive to the fact that their work exists in context of the entire property. These days, many include things like outdoor kitchens, adjacent hardscape, plantings and a wide gamut of…Continue
