Polished Pool Finishes in Flower Mound, TX

Prep and thickness

On a refinished pool, CL Industries calls for undercutting at least 3 inches around tile, return lines, lights and main drains, and an approved scratch coat, before Hydrazzo goes on. Its two documents differ on thickness: the data sheet allows up to 1 inch, the application sheet 3/8 to 3/4 inch, warning that thicker material needs layering and thinner material dries too fast and cracks or crazes.

Exposing and polishing

SGM's Durazzo cures overnight and is acid washed the next morning, starting at half muriatic acid and half water. The walls are polished before the floor, so nobody has to stand on a slick wet floor: one light pass of a 70-grit diamond disk over the whole pool, then a second at 120 grit where swim-outs, spas and other high-contact areas need it. CL Industries exposes Hydrazzo the same day after at least 4 hours of cure at 80°F and rising, or after an overnight cure, washing the walls from the floor up and the floor from the deep end to the shallow.

CL polishes with its water-driven Triton, run at 3800 to 4000 psi so the water keeps washing the dust away, keeps the abrasives off the tile line, and finishes corners, steps, benches and light niches by hand. It warns that metallic sanding discs or polishers driven by hydraulic oil can permanently destroy the curing of a cement finish.

Glass bead takes its own exposure

Pebble Technology International says glass finishes usually need different exposure methods from pebble finishes. Designer Concrete Coatings waits for a hard set, at least 24 to 48 hours after the work is finished, before the final acid detailing of Beadcrete, and warns that acid on a dry, green surface will damage it.

• Hydrazzo 3/8 to 3/4 in. (CL application sheet)
• Durazzo: 70-grit pass, then 120-grit (SGM)
• Triton polisher at 3800–4000 psi (CL)
• Beadcrete at least 8 mm (Designer Concrete Coatings)

From the fill to the first year

Pebble Technology International keeps its smoother PebbleFina and PebbleBreeze surfaces evenly dry until the fill, with no water dripping or puddling on them. CL Industries says a cement finish takes up to a year to cure, so the first 10 to 12 months of care matter most, and a Hydrazzo finish whose start-up went wrong can be acid washed and polished again.

Approved applicators and the makers' warranties

A polished finish's warranty is the maker's, on the maker's terms. CL Industries warrants Hydrazzo against manufacturing defects for 10 years only when a factory-approved applicator installs it and the owner registers within 30 days, and it doesn't count staining or hydration as defects; SGM gives Durazzo 1 year as standard, extended to 5 years for homes when registered. Ask any contractor which of these brands it is approved to apply.
