How to Renovate the Liner of a Swimming Pool


– Step 1: Deep clean your pool liner

– Step 2: Repair leaks and holes in your pool liner

– Step 3: Renovate the pool liner with an adhesive frieze

Over the years of use, a pool liner inevitably gets dirty, gets holes in places, and eventually discolors, especially above the waterline, giving it a neglected appearance. Before you consider changing the liner, an operation that represents a certain cost, you can undertake to rejuvenate it at little cost.

Here is a step-by-step procedure for renovating a pool liner.

Materials needed to renovate a pool liner

Burning alcohol $3 approx.
Pool brush $6 approximately
Rag Free
Magic sponge $8 approx.
Adhesive frieze $8 to $12 per meter
Cleaning glove $7 approx.
Repair kit (patches + glue) Starting at $6
Special rust stain cleaner Starting at $9
Degreasing product Starting at $7 per liter
Plastic squeegee $1 approx.
Spray to facilitate installation $12

1. Renovate the liner of a swimming pool by deep cleaning

Perform a global cleaning of the liner:

– Vacuum or robot in the pool.

– If you do not have a robot or if it does not clean the walls perfectly, vigorously brush the vertical walls with your wall brush to remove any algae residue.

– Use a liner cleaning glove.

– Wet the glove thoroughly and then pour a water line cleaner over it.

– Scrub the soiled areas in circles, one way and then the other.

– Emphasize the areas where the dirt is stubborn.

Use a “magic eraser”:

To fine-tune the cleaning in hard-to-reach areas, such as corners or around skimmers, use a “magic eraser” or “magic sponge” as follows:

– Slightly moisten the sponge or eraser, which will harden into a micro-thick material.

– Scrub the areas that remain dirty: the dirt particles are mechanically absorbed without the risk of damage to the liner.

Eliminate rust and brown stains:

– If your liner is stained with rust, use a special rust stain remover: pour a small amount on the cleaning glove and gently rub the stains.

– If your liner has stubborn brown stains, the problem is more complex.

2. Repair leaks and holes in your pool liner

If your liner is punctured in places or leaks, you can repair it with a repair kit with patches and specific glue.

Here is the procedure to follow:

– Apply the glue generously on the patch.

– Fold the patch in half.

– Unfold the patch underwater at the last moment.

– Apply the patch by pressing hard and smoothing it with the flat of your hand to eliminate all air bubbles.

– If you are repairing on the bottom of the pool, place a heavy object (such as a canister of water) on the patch for a few hours.

3. Renovate the pool liner with an adhesive frieze

Under the action of the sun, the liner fades, especially in its emerged part, which gradually tends to become almost white, which is not very aesthetic and gives a neglected aspect to your pool.

You can then apply an adhesive frieze to the water line yourself, which will camouflage the discoloration and also offers the advantage of being very easy to clean in the future.

Calculate the dimensions of the frieze this way:

2 × the length + 2 × the width of the pool = total perimeter

For example: for a pool of 8 × 4 m, you will need 24 meters of the frieze.

– Calculate the necessary height of your frieze: measure the height of the discolored liner starting from the top edge of the pool. Your frieze must cover at least this height + 3 cm.

Prepare the surface:

– Empty the pool a little to work out of the water.

– Degrease perfectly the surface where the frieze will be applied with a water line cleaner.

– Finish by wiping with methylated spirits and a cloth.

Glue the frieze:

– Spray the surface to be glued with a spray product specially designed to facilitate installation (sold by manufacturers of adhesive friezes).

– Remove the silicone paper that protects the adhesive side of the frieze.

– Apply the frieze starting at an angle, positioning it very precisely at the top of the liner.

– Make sure it is firmly adhered to a squeegee to prevent air bubbles from forming during gluing. Move the squeegee from the middle of the frieze to the outside top and then to the outside bottom.

– Before applying the frieze to the skimmers:

◦ Make a cardboard pattern with the exact dimensions of each skimmer.

◦ Place the pattern on the frieze where it will cover the skimmer.

◦ Draw the location of the skimmer on the frieze using the pattern and a felt pen.

◦ Scissor out the skimmer location.

– When the frieze is fully applied, wait 48 hours before filling the pool to its normal level.

And, that’s it. You are done. Remember to leave your comments in the section below.

What Should I Look for When Renovating a Pool


– Renovation to repair your pool

– Swimming pool renovation: to embellish or improve

– Who should I contact for pool renovations?

A swimming pool gets damaged over time and it is often useful or even necessary to renovate it. For renovations, whether it is essential or you simply want to embellish your pool, it is advisable to call a professional. Here is a brief overview.

Renovation to repair your pool

This renovation is often made necessary after years of use of the pool. A first step is to make an “inventory of fixtures” that will help determine existing problems.

The most common problems encountered are:

– Leaks in the hydraulic system: a search for leaks with specialized equipment or by doing tests makes it relatively easy to locate the origin of the problem. Depending on the design of the pool and the location of the leak, it may be necessary to open part of the walls or the bottom of the pool.

– Micro-cracks or cracks in the structure of concrete pools: it is possible, after treatment of the cracks, to put the pool back into operation. In some cases, it may be imperative to install a reinforced membrane or glass fibre reinforced polyester, for example. These will ensure that the pool is permanently watertight and give it a “facelift”.

– Blisters on the surface of shell pools: this phenomenon is well known as the osmosis phenomenon. A sanding, followed by the application of glass matting with resin and a gel coat finish and your pool is left for 15 years of good and loyal service.

– The liner is no longer watertight: a change of liner is necessary.

– The tile joints are in poor condition: it is then necessary to redo the joints after a few years and replace the lost tiles. This renovation is easy even if it is often difficult to find exactly the same tile.

– Changing a tile is also possible, even if it is a bigger job. Indeed, this requires (after demolition) a preliminary repair of the sealing compound.

Swimming pool renovation: to embellish or improve

Over the years, your pool will become obsolete, both aesthetically and technically. Indeed, new equipment is marketed every year, you can call upon a professional who will be able to advise you.

Among the possible renovations are the following:

– Replacement of a ladder by a stairway or an immersed beach, if the dimensions of the pool allow it.

– Installation of an immersed roller shutter, which is much more aesthetic than an above-ground shutter and easier to handle than a cover.

– Installation of a heating system, to extend the swimming season.

– Installation of balneotherapy nozzles in a shallow corner of the pool to create a relaxation and wellness area.

– Integration of a jacuzzi in the pool.

– Raising the bottom of a very deep pool and integration of an automatic bottom cleaning system.

This has the advantage of reducing the volume of water in the pool and therefore reducing the quantity of treatment products while benefiting from a powerful automatic cleaning system.

– Modification of the water circulation system by the creation of an overflow that will replace the skimmers. In addition to the technical benefit for the quality of the filtration, there is also an aesthetic advantage.

– Modification of the shape of the pool, creation of a terrace, a pool house…

Who should I contact for pool renovations?

All of the above renovations must be carried out by a professional who will be able to advise you on the feasibility of the planned renovation, taking into account the land, the structure of the pool and the existing installation.

The cost varies according to the work envisaged: from a hundred dollars to several thousand. Before committing yourself, it is of course necessary to obtain detailed estimates and compare them.
