Natural pool finish
Chukum pool plaster
Chukum lines pools with a seamless finish that colours the water and ages like stone. It is supplied by the original manufacturer, with stock in Europe.
Why chukum for a pool
No joints
A continuous 3–5 mm surface, without tile joints.
Natural colour
The tone comes from chukum tree bark extract, not pigments.
Cenote-like water
Under water, the natural finish gives the turquoise typical of Yucatán.
Repairable
Allows local repairs.
How it is applied in a pool
Substrate
Concrete shell with a rough cement render. Plumbing and electrics finished. Existing mosaic or tiles are removed and rendered.
Bonding coat
Adikum diluted 5:1 in water, or neat depending on the substrate.
Chukum Base in two coats
Base mixed with Agua de Chukum, trowelled and polished, 3–5 mm in total. Order: walls, benches and steps, then the floor.
Filling
24 to 48 hours after finishing. Keep the pool full for at least 15 days.
Water chemistry
- pH between 7.2 and 7.6 and Langelier index (LSI) between 0.0 and +0.3.
- Salt chlorinators are compatible if the pH stays in that range.
- Never drop chlorine tablets straight into the pool: they stain and attack the finish.
- Chukum Protect goes only on the coping and deck, never inside the submerged shell.
- Decks and barefoot areas must stay slip-resistant: the finish texture is adapted for this.
Frequently asked questions
Can it go over mosaic tiles?
Not directly: tiles are removed and the shell rendered with cement mortar first.
Can Extra-fine Paste be used in a pool?
No. Pools and floors use Chukum Base only.
Does it work with a salt chlorinator?
Yes, as long as the pH stays between 7.2 and 7.6.
Which colours suit a pool?
Natural cream gives the classic turquoise; grey gives deeper water. Order physical samples before deciding.
