Hello to All,
Hope this is in the right forum section since I did not see another section for a topic of this nature - your help is appreciated.
We have a tumbled travertine installed in a Versailles pattern around pool and outside kitchen area. It is an ivory color and with a lot of moisture in West Houston, there has begun some staining of dark colors in the pitted areas, which I am sure it mold.
When the PB contractors installed the plaster/pebblesheen, I came home and a guy was using a power washer to "wash off" any plaster residue from areas around the pool. The idiot was using a power-washer that was 3500psi, thus blowing out all of the natural material in the travertine decking. This is the softer material that is formed in the crevices and smaller holes of the travertine. I immediately stopped him and you can see the differences in the stone that was blasted and the stone that was not. Some larger holes and other are now forming dark mold.
My goals are as follows
1. Properly clean the entire area w a 500-600psi and remove mold and other loose debris [Is there a none harsh, not acid based chemical that can help w this process??
2. Once the surface and holes are all cleaned-out and now pristine again, what can I use to fill the larger holes that will match as close a possible to the travertine, and if it weathers, they both weather the same [filled-hole and travertine]?
Once (2) above is done, is there anything else you recommend? I do not want to seal the stone except the coping. I do not mind an annual cleaning of a light power-washing or other.
Lastly, some of the polymeric sand used has turned dark and moldy. What do you suggest I do for these areas?
I am looking at 500sqft near the pool which 1/2 was blasted. Another 700sqft to clean that is in a covered & transition area. I just want to clean this and fill a few natural holes that are too large and keep getting debris in them.
if you have any questions, pls let me know? The pool water is CL based, not salt for the obvious reasons. No acids or harsh chemicals of any kind can be used.
As always, thank you very much for your feedback. You guys are great.
Regards,
