Benefits of Using ecoFINISH for Hot Tubs and Spas

ecoFINISH offers many perks for hot tub and spa owners. This coating system boosts durability, cuts down on upkeep, and makes your spa look great for years to come.

Durable and Long-Lasting Coating

ecoFINISH creates a surface that resists fading, staining, cracking, and flaking. It’s strong enough to handle high temperatures, frequent use, and fluctuating pH levels—ideal for hot tubs and spas.

The 10-year warranty on aquaBRIGHT (and extended life expectancy on both systems) gives spa owners peace of mind.

Resistant to Chipping, Peeling, and Cracking

ecoFINISH coatings are engineered to handle the constant expansion and contraction that occurs in spas due to temperature changes. That flexibility means the finish stays smooth and intact longer than paint or plaster alternatives.

Low-Maintenance Surface

Thanks to its non-porous surface, ecoFINISH resists algae, scale buildup, and staining—making cleaning easier and faster. The surface wipes clean and doesn’t trap grime, reducing the need for scrubbing and aggressive chemicals.

pH-Neutral

ecoFINISH coatings are pH-neutral, which helps maintain water balance and reduces the need for harsh chemical treatments. That means softer water for your skin and eyes, and longer equipment life for your spa.
