Product Details
WINWINPOOL POOL PAINT SYSTEM 100SQ–120 MICRONS is a swimming pool paint kit for concrete pools, with quantities calculated from surface area and target film thickness. It suits an internal pool surface of approx. 95-100 m², such as a pool of about 5 × 10 × 1.5 m (approx. 75 m³).
The system is applied in 3 coats: 1 coat of Concrete Sealer epoxy primer and 2 coats of Unithane W-4000 polyurethane topcoat. The target dry film thickness is approx. 40 microns per coat, for a total of approx. 120 microns.
Extra quantity is included to allow for mixing losses, paint left in containers and on rollers, and surface roughness, porosity and absorption reducing the risk of running short mid-job.

How We Calculate Area and Paint Quantity
Example: 5 × 10 × 1.5 m poolFloor: 5 × 10 = 50 m²
Walls: (5 + 10 + 5 + 10) × 1.5 = 45 m²
Total surface: 95 m² use the 100 m² kit
Concrete Sealer primer (1 coat)Area for 1 coat: 100 m²
Approx. coverage ~52 m² per set per coat
100 ÷ 52 = 1.92 sets (theoretical)
Supplied: 3 sets to allow for concrete absorption, roughness and application losses
Unithane W-4000 topcoat (2 coats)Area for 2 coats: 100 × 2 = 200 m²
Approx. coverage ~41 m² per set per coat
200 ÷ 41 = 4.88 sets (theoretical)
Supplied: 6 sets for consistent film thickness across the whole surface
Coverage rates are estimates. Actual consumption depends on surface roughness, porosity, absorption, application method, tools and site conditions.
Film Thickness Control
Formula
WFT = DFT ÷ Volume Solids
DFT = dry film thickness · WFT = wet film thickness
Total DFT = DFT per coat × number of coats
Preliminary estimate at ~55% volume solids
Wet film per coat: 40 ÷ 0.55 73 microns
Total wet film: 73 × 3 219 microns
We recommend checking with a wet film thickness comb during application to keep thickness even across the pool. (The wet film comb is optional and not included in the standard 21-piece kit.)
Surface Preparation
- New concrete should cure for at least 28 days
- There must be no hydrostatic pressure or trapped moisture behind the surface
- The surface must be clean and dry, free from dust, oil, grease, algae, efflorescence and deteriorated old paint
- Sand or grind the concrete to open the surface for good adhesion
- Repair cracks, voids, joints and defects before starting
- Remove all sanding/grinding dust and let the surface dry completely
- Measure moisture at several points, especially the floor, deep end, corners, joints and newly repaired areas
Moisture requirementsCheck moisture with the concrete moisture meter before every coat. If the meter reads in percent, we recommend no more than 4%, or follow the meter and coating manufacturers' standards.
Do not paint when- The surface is wet or seeping water
- There are water droplets or dew on the surface
- Relative humidity is above 85%
- Surface temperature is below the dew point
- The concrete has hydrostatic pressure from behind
Surface temperature should be at least 3°C above the dew point
Mixing 2-Part Coatings and Using Thinners
How to mix A+B- Stir Part A until uniform before mixing
- Add Part B to Part A at the ratio on the label
- Mix with a low-speed mixer until uniform
- Mix only what you can use within the pot life
- Never estimate the ratio by eye
- Do not add more A or B after mixing
- Do not pour mixed paint back into the original can
W-M68
Use only with Concrete Sealer (coat 1)
W-M22
Use only with Unithane W-4000 (coats 23)
Add thinner only when needed for the application method, weather and label instructions. Over-thinning causes thin film, sagging and reduced coverage. Never use the wrong thinner or mix the two thinners together.
Application Steps
Inspect and prepare the surfaceClean and open the concrete surface, repair cracks and defects, remove dust and dirt, and measure moisture at several points. Start only when the surface passes.
Concrete Sealer primerMix A+B per the label, use W-M68 only if needed, apply evenly and continuously at ~40 microns DFT. Avoid pooling, sags and thin spots.
Touch dry ~4 hNext coat after 14 h
Check before the first topcoatConfirm the primer is dry and well bonded, with no dust, moisture, water droplets or dew. Measure moisture before painting. If the recoat window has passed, sand to key the surface and clean before continuing.
W-4000 topcoat coat 1Mix A+B per the label, use W-M22 only if needed, and apply evenly at ~40 microns DFT.
Touch dry ~1 hRecoat after 3 h
Check before the final coatRe-check surface and moisture, remove dust, nibs, sags and dirt, and ensure there is no dew or condensation. Fix any defects before the final coat.
W-4000 topcoat final coatApply evenly and continuously at ~40 microns DFT, checking for thin spots, misses and runs. Total system dry film thickness approx. 120 microns.
Cure 5 days before filling
All times are referenced at approx. 23°C and vary with temperature, humidity and ventilation.
Curing time before filling
At least 5 days
At approx. 23°C after the final coat. Allow longer in cool, humid or poorly ventilated conditions.

Frequently Asked Questions
What pool size is this kit for?
An internal surface (floor + all walls) of approx. 95100 m². For example, a 5 × 10 × 1.5 m pool (approx. 75 m³) has about 95 m² of surface.
Why is there more paint than the theoretical calculation?
Theoretically you need about 1.92 sets of Concrete Sealer (1 coat) and 4.88 sets of W-4000 (2 coats), so we supply 3 sets of Concrete Sealer and 6 sets of W-4000 to allow for concrete porosity and absorption, surface roughness, and losses in mixing, containers and rollers.
Can W-M68 and W-M22 thinners be swapped?
No. W-M68 is only for Concrete Sealer and W-M22 is only for Unithane W-4000. Never use the wrong one or mix the two.
How dry must the surface be before painting?
If the meter reads in percent, no more than 4% (or per the manufacturer's standard), relative humidity no higher than 85%, and surface temperature at least 3°C above the dew point. Check before every coat.
How long before I can fill the pool?
At least 5 days at approx. 23°C. Allow longer in cool, humid or poorly ventilated conditions.
Can I choose the pool colour?
Yes. The Unithane W-4000 topcoat is available in a range of colours tell our team your choice when ordering. Actual colour may differ slightly from on-screen images.
Can it be used on a previously painted pool?
Yes, for renovation work once the surface is properly prepared, deteriorated old paint is removed and cracks are repaired. We recommend sending photos of the pool for our team to assess before ordering.
Is a wet film thickness comb included?
No, it is an optional extra. The standard 21-piece kit includes one concrete moisture meter.
My pool is larger than 100 m². What should I do?
Send us the width × length × depth and our team will calculate the area and recommend the right kit size.
How long is the warranty?
Up to 3 years, subject to company terms. It does not cover damage from structural issues, moisture, surface preparation or use not in line with the instructions.
Note: Actual product colour may differ slightly from on-screen images. Consumption and drying times are estimates and vary with temperature, humidity, ventilation, application method and surface conditions. Please confirm colour, quantities and application requirements with our team before ordering.
Want to check the right paint quantity for your pool?
