The best swimming pool paints, compared.
Top pick: Mollor Acrylic Blue 4.1 L Best value: Quimicamp Clorocaucho – Lowest captured shelf price at about £49. Coverage is not stated, so this is not a cost per square metre. Updated 16.10.2026.
Swimming pool paint is a coating sold for total immersion on a concrete shell that already holds water. It will not repair a leak, it is not a finish for a vinyl liner, and it is not a masonry paint whose colour happens to be called swimming-pool blue. Says paint belongs on concrete, that new render or screed should cure for at least 28 days, and that nobody can promise a service life, because the shell stays wet. A usable listing states the substrate, the yield, and the wait before you refill. Match the new coat to the old film. None of these five tins is labelled epoxy. Whether a shell should be painted at all is covered in the [concrete pool paint guide](/hub/pool-care/swimming-pool-paint/sub/swimming-pool-paint-concrete). Even then the film cannot be promised a service life, because the shell stays wet and groundwater can push from behind.

Personal buying guide
Question 1 of 2
What are you painting?
Mollor is listed at about £89.99 for a water-based acrylic blue pool paint, 4.1 litres, matte, weight 5 kg, origin China. The surface field says concrete. A bullet states about 320 sq ft per coat on smooth bases and 200 sq ft on rough bases, and claims performance under 30 metres, which is the listing’s wording. amazon.co.uk shows 5.0 from 6 reviews. The written reviews in the file are from the United States: easy water-based application, more paint on rough areas, and several dry days before the pool goes back into service. That is not a UK sample. Rank in the capture is 15 in Pool Paint (DIY & Tools).
Pros
Cons
Best for: A cement pool where you want a one-pack blue acrylic and you have read that the reviews in this capture are from the United States.
Less suitable: A buyer who needs a UK review sample, a printed fill-wait in days, or a fibreglass claim in the specification field.
Specifications
Common questions
What coverage does the Mollor listing state?
A bullet says about 320 sq ft per coat on a smooth base and 200 sq ft per coat on a rough base. The title says 138 fl oz and one bullet says 128 fl oz. The size field is 4.1 litres.
Are the six reviews from the UK?
The listing score is 5.0 from 6. The written reviews in the capture are from the United States. One German review has no sentence. They describe roller or brush use, lower yield on rough areas, and a cure of several days.
Does the specification say fibreglass?
The surface recommendation field says concrete. A prompt asks about fibreglass and the field does not answer yes. Fibreglass appears in a US review, not in that field.
EPODEX is listed at about £84.75 for a 2 kg jet-black pastel kit. The bullets call it a 2K PU paint for concrete basins and saltwater pools, mixed 3:1 with 5% colour paste, covering about 9 m² at two coats. The cure fields say 6 hours. Do not treat that cell as a safe time to fill. The item-form field says Powder, which conflicts with a liquid two-pack. amazon.co.uk shows 5.0 from 1 review, written in Italy, with no job detail. Rank in the capture is 16 in Pool Paint (DIY & Tools).
Pros
Cons
Best for: A small concrete area, including a saltwater pool as the listing states, where you will mix a 2K PU kit and the colour you want is jet black.
Less suitable: A full domestic shell that needs tens of square metres, or a one-pack roller job with a multi-day fill wait printed on the tin.
Specifications
Common questions
How does the listing say to mix this paint?
Mix resin A and hardener B at 3:1, add 5% EP colour paste, and apply thin coats with a roller, walls first then the floor.
What area does the 2 kg kit claim?
About 100 g/m² per coat, and about 9 m² for the 2 kg kit with two coats. Saltwater pools and concrete basins are named.
What cure time is printed?
The full-cure field says 6 hours and the dry-time field says 6.0 hours. That is the listing cell. The file does not contain a separate multi-day fill instruction. Do not treat 6 hours as a safe time to fill.
Titan is listed at about £51.15 for 4 litres. The bullets call it a matte water-based paint for indoor and outdoor cement or concrete pools, with a yield of 9–11.5 m² per litre, dry time 30–60 minutes, recoat 18–24 hours, and a wait of 7 or 8 days before filling. The colour field says multicoloured while the title says Matte Blue. The paint-type field says Watercolour and the item form says Powder, which conflicts with the liquid description. Rank in the capture is 12 in Pool Paint (Garden). There is no review line. It is the top pick where you want the yield and the fill wait printed on the listing.
Pros
Cons
Best for: A cement or concrete pool where you want the yield and the 7 or 8 day fill wait printed on the listing.
Less suitable: A liner or fibreglass shell, which this listing does not claim, or a buyer who needs UK reviews before ordering.
Specifications
Common questions
Does the Titan listing say it can be used indoors?
The bullets say a matte water-based paint for outdoor and indoor cement or concrete pools. They do not mention a liner or fibreglass.
How long does this listing say to wait before filling?
The bullets say drying time 30–60 minutes, repaint after 18–24 hours, and wait 7 or 8 days before filling the pool.
What coverage does the 4 litre tin state?
The bullets state a yield of 9–11.5 m² per litre, applied by brush or roller. The file has no review count.
Quimicamp is listed at about £49, the lowest price in the five kept pool paints. The title says anti-algae paint AL CLOROCAUCHO, the model number is Branco / 5 L, the weight is 5 kg, and the country of origin is Portugal. The capture has no coverage, recoat, fill wait, substrate, finish, or reviews. Best value here means the shelf price only, not a cost per square metre.
Pros
Cons
Best for: A buyer who already knows this chlorinated-rubber line and only needs the white 5 L tin at about £49.
Less suitable: Anyone who needs a printed yield or a fill wait before they order, which this capture does not contain.
Specifications
Common questions
What does the Quimicamp title say the paint is?
The title is Anti-algae paint AL CLOROCAUCHO. The model number is Branco / 5 L and the weight is 5 kg. Coverage, dry time, and a fill wait are not in the file.
Is a substrate listed?
No. The file does not say concrete, fibreglass, or liner. Branco on the model number is the colour word white.
Why is this the best-value pick in this set?
It is the lowest captured shelf price at about £49 among the five pool paints kept. The pick is that price position. It is not a cost per square metre, because coverage is not stated.
CTX is listed at about £80.25. The title says CTX-140 and CTX-141 pool paint. The model number is CTX-141 - Branca, the weight is 4 kg, the part number is FLU09472, and the country of origin is Portugal. Coverage, chemistry, finish, substrate, cure, and reviews are not in the file.
Pros
Cons
Best for: A buyer who already uses CTX-141 white and only needs this 4 kg listing at about £80.25.
Less suitable: A first-time order that depends on coverage, chemistry, or a fill wait, none of which are in the capture.
Specifications
Common questions
Which CTX code does the model field name?
The model number is CTX-141 - Branca. The title also names CTX-140. The file does not say whether both codes are in the pack.
Does the listing say how to apply it?
No. Prompts in the file ask about outdoor pools, other colours, and easy application. There is no answer text, no yield, and no fill wait.
What is the pack size?
The item weight is 4 kg. A litre volume is not stated. The price in the capture is about £80.25.
Five swimming pool paints on amazon.co.uk were compared from the listing captures dated 16 October 2026 and from public UK sources, including SPATA, the VOC in Paints Regulations 2012, and HSE INDG273. There was no lab test and no immersion trial. The 1–10 figure is how complete the listing is against the weights below. It is not an amazon star average. Three captures have no review line. The two star lines are 5.0 from 1 and 5.0 from 6, and the written reviews are not a UK sample.
Shell and substrate
25%The tin should name concrete or cement. A liner is out. Ordinary acrylic is the wrong default on one-piece fibreglass.
Coating family
20%Water-based acrylic, chlorinated rubber, or two-pack polyurethane, matched to the old film. Switching families without stripping is a reason to stop.
Sold for pool water
20%The listing has to be pool paint for immersion, not a blue masonry paint, a garage-floor coating, or a colour name on its own.
Fill wait on the tin
20%A printed wait before refill, in days where the maker gives days. Touch-dry is not cured. A 6-hour cell is not treated as a safe fill time.
Yield against price
15%A stated yield, read at the rough-surface figure and two coats, set against the shelf price in GBP. No yield means the low price is not a cost per square metre.
Buy the tin for the shell you have, not for a colour name. Concrete that already holds water is the starting point. A liner, a leak, and render under 28 days are reasons to stop. Then match the old coating, read the yield at two coats, and read the wait before you refill. Prices below are amazon.co.uk shelf prices on 16 October 2026.
A swimming pool paint, for a UK buyer, is a coating rated for total immersion on a concrete shell that is already watertight. It is not a leak repair. SPATA says paint does not make the pool watertight, and that new render or screed should cure for at least 28 days before you paint. Even then the film cannot be promised a service life, because the shell stays wet and groundwater can push from behind. Cementitious masonry paint is not pool paint, even when the shade is called swimming-pool blue.
Swimming-pool blue on a masonry tin is not pool paint. SPATA excludes cementitious wall paint. The tin has to be sold for pool water.
Touch-dry is not cured. Titan’s bullets say 7 or 8 days. Other makers publish different waits for their own products. EPODEX’s 6-hour cell is not a safe fill time.
Mollor is 5.0 from 6 on amazon.co.uk. The written reviews in the capture are from the United States. They are not a UK sample and not a lab score.
The first question is the shell, not the shade. SPATA places swimming pool paint on concrete that has been tested for water tightness. Liner pools are out. One-piece fibreglass, if it is painted at all, is a specialist epoxy conversation, and ordinary acrylic is the wrong default. New render or screed should cure for at least 28 days. Paint does not make a leaking shell watertight. The second question is the film already there. Stay with the same family.
Take the wait before you refill from the tin in your hand. Titan’s bullets say 30–60 minutes to dry, 18–24 hours to recoat, and 7 or 8 days before filling. Other UK makers publish 5 days, 7–10 days, 10–14 days at 20°C, or 14 days, each for their own product. Touch-dry is not cured. EPODEX’s cure fields say 6 hours, with no longer fill instruction in the file. Do not treat 6 hours as a safe time to fill. Quimicamp, CTX, and Mollor’s specification line do not state a fill wait.
Three typical situations, each with a recommendation from this comparison.
You have a concrete pool that already holds water, you know the old coating, and you can empty it, roll two coats, and wait. Titan Mermaid 4 L is about £51.15. The bullets state 9–11.5 m² per litre and 7 or 8 days before filling. There is no review line.
You already know this chlorinated-rubber line and you want the white tin at the lowest price in the set. Quimicamp Clorocaucho is about £49, model string Branco / 5 L, weight 5 kg. Coverage, substrate, and a fill wait are not in the capture.
You have a small concrete area, including a saltwater pool as the listing states, and the colour you want is jet black. EPODEX is about £84.75 for 2 kg, mixed 3:1, about 9 m² at two coats. The cure fields say 6 hours. Do not treat that cell as a safe fill time.
In this set of five amazon.co.uk listings, the top pick is the Titan Mermaid 4 L at about £51.15. The bullets name cement or concrete, a yield of 9–11.5 m² per litre, and a fill wait of 7 or 8 days. There is no review line, and two catalogue fields disagree with a liquid blue paint. The best value is the Quimicamp Clorocaucho at about £49, which is the lowest shelf price only. Coverage is not stated, so it is not a cost per square metre. None of these tins waterproofs a leaking pool, and none is a vinyl-liner finish.
Quimicamp Clorocaucho
Lowest captured shelf price at about £49. Coverage is not stated, so this is not a cost per square metre.
