Pool Painting

Three kinds of pool painting can be done after water blasting, sanding or grinding down the old pool surface. Pool paint is a great way to resuface pools. More information on the process of repainting pools below:

SURFACE PREPARATION



                                           To remove existing paint can be done in two ways.

To remove existing paint can be done by Grinding or Sandblasting.
Grinding requires patience, good breathing and safety gear. Also the finish you will want to achieve will take a lot longer grinding  than it does by Sandblasting.

The best advice we can give you is to take the existing paint off. Starting with a clean substrate is a very comforting thought.
However if the Pool has been already painted then a 3000 psi water blaster in conjunction with an approved De-greaser is a common practice.
If Northern Pools Ltd is involved then you would find us washing the surface down with brush and De-greaser. Making sure all of the De-greaser has been removed, then water-blasting. The reason for this is that you will find that if bare concrete or plaster is exposed then the De-greaser will be driven into the porous surface. This results in a dropping of the pH value of the shell.
A pH of 7 is desirable. ( slightly higher is ok, but defiantly not lower )
It pays to test before painting. ( The test strips you use for spa or pool water with suffice. )

        There are three types of paint you can use for the painting of your Swimming Pool.


1 / Chlorinated Rubber

2 / Two Pot Epoxy

3 / Acrylic                                                         Chlorinated Rubber

 A Chlorinated paint is mainly used if the Swimming Pool has the history of slight movement. Ground instability or Thermal expansion and contraction, more common on infinity pools, where walls are exposed to the Suns heat on the outside, with the pool interior been cooler.
 When painting with A Chlorinated Painting system it is important that a Mohair Roller is used. This will help with the Solvent bursts that is a common character with this type of paint. If this does occur then with a wide fine brush softly touch the freshly painted surface with soft smooth strokes.
 Choosing to paint in the heat of the day in direct Sunlight is not something we would recommend as this increases the risk of a disappointing outcome.
 As always follow the instruction on the Tin.

                                                                             Epoxy

  The Epoxy option, if the Swimming Pool is structurally sound would be the preferred option as it is extremely hard and isn't prone to Solvent bursts. When mixing the two parts that make up the Epoxy, stir by hand for five minutes. ( If instruction say stir gently )Otherwise use a Mixing Wand on the end of a drill for 4 minutes.
 Leave standing in the shade for 15 minutes before applying. A fine hair roller will do the job. Do not paint over Chlorinated paint with Epoxy. This WILL fail.

                                                                          Acrylic

The Acrylic option is only chosen if you are happy to paint again next season. It is not designed for total submersion, not to mention the unique environment of a Swimming Pool.
