plasterers know how to get
the mix right, with numerous variables
that can affect the finished product. They
also work in a team of 4 - 6 workers, to
get it up before it sets (and cracks).
Small patches? OK, but re-plastering the
entire pool? I would leave that to plasterers.
If YOU prep the pool for plaster, however,
you could save 25% or so on the job.
is the procedure for starting up a freshly
are basically two methods, chlorine start,
or acid start. I do the acid start which
eliminates the brushing and filtering of
plaster dust. The idea is to drop the Total
Alkalinity level to zero, and then
rebuild it with the carbonates that are
contained in the plaster dust.
how I do it. As the pool is filling, immediately
after plastering, add 1 gallon of muriatic
acid directly to the water (don't splash
it on the bare plaster) per 5,000 gallons
of fill water. With a watch, time the amount
of time it takes to fill up a 1 gallon
or 5 gallon bucket with the hose(s) used
to fill up the pool. Do the math to determine
how many gallons are added every hour.
Divide 5,000 by the number of gallons coming
out of your hose(s) per hour, and you will
know how long it takes to fill 5,000 gallons
from the hoses.
the pool is full, test the Total Alkalinity.
It should be zero. Then test the pH,
and do a base demand test to determine
how much pH increaser to add. Add up to
6 lbs of pH increaser at a time, brushing
the pool to distribute fully. Wait a few
hours in between 6 lb additions. When all
of the pH increaser is added, recheck pH
and Total Alkalinity. Add additional increasers
Hardness levels. If below 180 ppm,
add Calcium Chloride in dissolved form
to bring the levels up. Brush pool after
any addition of chemicals. When pH, Alkalinity
and Calcium levels are balanced, slowly
begin to chlorinate the pool. Do not
shock the pool for a week or so. Leave
the pool filter (and heater, and pool
cleaner) off until the chemistry is balanced.
