Replaster Your Pool in 11 Steps Replaster Your Pool in 11 Steps

Replastering a pool is certainly not a 5 minute job, if you’re willing to put the time and effort into the work. It’s almost certainly something you can do yourself with a view to saving money on employing a professional. The average gunite swimming pool will need replastering every 7 to 12 years, depending on the way in which it was installed and on how well it’s been used and maintained. One reason for replastering is cosmetic, and it’s possible for the walls of a pool to become discolored quickly. If the walls of your pool look brown or green instead of the clean blue you desire, you might well think about undertaking the replastering work straight away. Follow these 11 steps and you should have a beautifully replastered pool that will be the envy of the neighborhood.

Step 1 – Sump Pump

Turn off all working equipment and drain the swimming pool. Use the sump pump to clear any water that remains at the bottom.

Step 2 – Cleaning

Clean the drained pool of dirt and debris such as leaves. Use the sponge and some ecologically friendly solution to get it clean.

Step 3 – Problem Areas

Identify problem areas, where plaster is peeling significantly. Pay special attention to edges and corners.

Step 4 – Use the Chisel

Take loose plaster away with the chisel or a putty knife.

Step 5 – Sanding

Sand sharp edges where plaster has been removed, so as to make re-plastering easier. Sand at least twice so that the area is neat and clean.

Step 6 – Acid

Pour or spray an acid wash over the surface. Use an acid brush to spread it effectively. This will render the new surface conducive to accepting new plaster.

Step 7 – Use the Hose

Rinse away the acid wash with a hose and allow the surfaces time to dry. Once done, apply a bond coat for replastering using a roller. Let this dry overnight.

Step 8 – Apply Plaster

Prepare the plaster to be used according to manufacturer’s instructions then apply it using the steel trowel. Starting at the deepest end of the pool, ensure that the plaster you apply has a thickness of 3/8 inches. Be careful not to apply wet plaster to set plaster and fill in any cracks or holes. Ensure an even surface. Now, let the plaster dry.

Step 9 – Finish

Mix the plaster finish and again use the trowel to apply it evenly at a thickness of 1/4 inches.

Step 10 – Check

Inspect your work for any flaws, and wait for the plaster to dry completely.

Step 11 – Painting

Apply specially produced pool paint. Make sure you cover the entire surface and apply paint evenly. Use the brush in one direction so as to give a smooth finish. Don't use the pool till the paint dries up properly.

Now, refill the pool, chlorinate the water and enjoy the benefits of your hard work.
