Design considerations using polished plaster in swimming pools and wet areas
The specification of decorative finishes for high humidity or wet areas (such as swimming pools, spas and bathrooms) can be a challenge. Polished plaster can provide a perfect choice for demanding interiors which require a high-end aesthetic. Natural mineral finishes are breathable and provide excellent resistance to mould, fungal or algal growth.
Polished plaster can be used to great effect in wet areas to provide a seamless monolithic highly polished surface. Tough and hard wearing, these creative finishes can also produce rich and diverse decorative effects, such as blockwork or seamless Travertine stone, and complement other natural materials such as glass, stone and timber.
Polished plaster application should be carried out when the pool is empty or good ventilation and humidity control are present. Humidity levels need to be low to ensure adequate drying rates. The finishes should only be applied to the walls of the swimming pools that will be occasionally splashed, with a recommended distance of 1.5m from wall to poolside. There should always be a water seal along the floor/wall to avoid damage from rising damp. A 600mm stone or tile skirting offers good low-level protection against wear and tear and is ideal for separating the wet floor from the polished plaster, but a good water seal is also required.
Once these simple steps have been considered, polished plaster can create a luxurious and opulent wall finish highly suited to this demanding interior space.
