Sealing cultured stone
I have cultured stone half way up the house. See avatar pic. The stone is very nice but is fading because I have direct sun from noon on until it sets. Gets real real hot...when it rains if it gets wet this dry white powder builds up. I wanted to seal it but many people say they are having problems with the sealing of stone especially with direct sun exposure. Any thoughts?

Don't know?...ask someone...

,,, then they're using the wrong sealer - probably bought from an apron/vest store :furious: your ' cultured stone ' doesn't mean your stone is proficient in opera, symphony, literature, etc - its really conc & all wtr bas'd color fades somewhat,,, find a solvent-based sealer that's uv-resistant,,, seal it in the am before the sun bakes it too much & it'll sound like you glued on bubble-wrap :yes: when you rub your hand across the ' stone '

ps - including your location's a HUGE help to responders when asking for advice

IF you need a product, we've used ' CSS ' from eliteCrete [ no financial interest ] about 15 yrs to seal decorative conc AND real/faux stone,,, due to its hi solids content & also being laced w/methyl-methacrylate, we cut it 1CSS : 1 1/2xylene then apply 2 lite spray coats,,, xylene flashes off in less than an hr so spray on another coat,,, IF you get runs, wipe it off quick,,, it will appear slightly glossy when finished but the shine will fade,,, only 1 caution - you'll need to do this again in a couple years,,, i seal our driveway every other yr,,, should resolve your efflorescence problem, too

mention'd application in 1st response,,, you will need solvent-resistant sprayer ( viton seals ),,, IF you don't need a good sprayer, rent it,,, SOLO is the best !
