When to Refinish Your Swimming Pool?

Some of the signs that homeowners should look for that would indicate that now is about the time for them to consider re-plastering their swimming pool would be:

  • With the plaster you’ll probably start to notice – the first thing you’ll notice is as you and your friends and family are using the pool, the bottom’s starting to feel a little rough; more like sandpaper than the old, slick and smooth interior finish.
  • You’ll notice some staining and discoloration.
  • Some delamination’s occurring where you’re getting spots that are actually popping off where you’re seeing the raw Gunite or shotcrete underneath of there.
  • And then of course some people decide it’s just time for a facelift; like to change the color and that’s another reason as well that people decide to resurface their pool.

For folks that are considering or believe to be ready to go and make the plunge right now to go and re-plaster, there are several things you should look for when choosing a company to do the work for you.

Make sure you’re having your pool resurfaced is to get it done by a reputable company that’s done a lot of whatever products you decide to use. The main thing with doing a resurfacing project is it’s much like painting your house. About 80% of the work is in the prep and then about 20% is in the application of the actual product. Look for references or have them show you the processes that they take and of course the products that they use.

What specific things happen during the prepping process?

The way contractors prep a pool for resurface is they go in and chip out around your fittings and underneath your tiles about two to five inches so the new plaster will come in and flow flush with those fittings and tiles. And then they’ll apply what’s called a bond coat over the existing plaster or finish, and that’ll give the new product a better surface to adhere to so it’ll stick to that existing surface. Many contracotrs skip the bond coating even though it is very important. It is like painting a black wall white with no primer. The bond coat is the primer, so make sure whom you hire includes that step.

Is there a typical life expectancy on the concrete pools when it comes to needing to re-plaster?

With concrete pools the plaster – most cement based plasters, whether it’s a Marcite, a plaster or a quartz based finish, they usually come with a one to three year warranty. And as long as you keep your water chemistry right, they can easily last eight to ten years. Now if you don’t use a product and keep your pH in balance, those pools can easily deteriorate right after that three to four year warranty period. With the concrete pools, as well, if you have a pebble type of finish, generally they come with a longer warranty and they’re going to last a lot longer. You’re going to pay a little more for them up front, but generally the pebble comes with either a ten or fifteen year warranty. And realistically, unless you want to change the color of your pebble finish, that’s going to stay with you, you know, a good 15 or 20 years.
