Plaster Installation
Ten Guidelines for Quality Pool Plaster There are proper steps to follow for the making of durable pool plaster. There are also improper practices that can lead to early deterioration, discoloration or other failures. Above is a ten-point checklist that will help achieve a lasting and discoloration-free plaster.
A Plastering 'Watch List' Taking control of the plastering process is within reach of any quality-oriented designer or builder, declares Kim Skinner. To help you on your way, he offers this step-by-step guide to managing what should happen on site before, during and after plaster application takes place.
Not All Color Pigments are Good for Pools It appears the plaster products that contain “organic” pigments become bleached (loss of color) over time when subjected to chlorine (an oxidizer). But products with “inorganic” pigments generally do not become bleached. Additionally, experiments which subjected both organic and inorganic pigments to LSI aggressive water showed that neither type of pigment lost their color from etching.
The Art of Good Pool Plaster Color
Installation Tips
Take a sample from every batch of the plaster while it is being applied. Use plastic cups and write on the cup the date, time, address, and batch number. If there is a problem later, you can send the sample to the lab without having to take a core out of the pool.[1]
Plaster Maintenance
The CSI is Reliable for Plaster-based Pools
All Plaster Finishes Should Last 20 Years
Pool Water Balance is Not (Always) the Problem The Bottom Line - Maintaining slightly aggressive water (LSI or CSI of -0.1 to -0.5) is acceptable. It does not cause rapid plaster deterioration and discolorations problems on quality applied pool plaster. The plaster problems mentioned in the thread are prevented by following good workmanship standards. Right now, there are none.
New plaster on renovated pool- when to refill?
Reducing High Calcium Levels in Pools
High CYA Levels Do Not Stain Plaster Contrary to some misinformation that has lately been floating around in the pool industry, high cyanuric acid (stabilizer) levels do not cause gray discoloration, or white spotting (“spot etching” as some incorrectly call it) in plaster swimming pools, no matter what. And there are several studies that have documented that.
Plaster Problems
Being Blamed for Plaster Discolorations? Don't Get Hoodwinked Some newly plastered pools (including quartz and pebble finishes) may develop either white soft spotting (also called "spot etching" by some plasterers), streaking, calcium nodules, gray mottling discoloration, spalling (flaking), or severe craze (check) cracking within a few months after being plastered, and whoever has been maintaining the water is often incorrectly blamed for those plaster problems and defects.
Diagnosing Pool Plaster Problems'
White Spotting of New Plaster Pools The problem of plaster spotting has been an ongoing puzzle and controversy in the swimming pool industry for over three decades. The generally round, smooth-yet-unsightly white soft spots in new plaster pools have long been a source of contention among pool plasterers, and pool chemical service firms or pool owners, each blaming the other for the phenomenon.
How White Pool Plaster Turns Blotchy This experiment below explains how white pool plaster can become blotchy gray, and also have white areas mixed into the gray areas.
How White Pool Plaster Can Turn Gray One would think that when mixing white cement with white limestone aggregate, the final pool plaster product would always be white. But that is not always the case. Unfortunately, white pool plaster sometimes turns gray (or grey) either immediately or a few months after the pool is filled with water. So what causes that to happen?
Calcium Nodules in pools What are calcium nodules? In swimming pools and spas, they are small mounds, bumps, deposits, or “slag” piles of calcium carbonate which are formed from material that has been released from the plaster. The small calcium nodules are rough to the touch, hard, and generally gritty. Nodules may form singularly (far apart or sporadically), or many and close together along a crack in the plaster surface.
