Hello to all,
On approx. 1275 sqft of pecan-colored tumbled travertine [non-sealed], pool decking pavers in the Versailles pattern, the polymeric sand btw the travertine pavers is now black and moldy. This was installed in Nov 2014, pool water filled later Feb 2015.
What product and/or process is there to get this back to the original colored [off white/light gray]? Also, some of the tumbled travertine pavers where there are natural pits, also have mold in them too. Suggestions to clean these areas? Also, there are some area's where the pavers intersect and if all four intersecting pavers have a depression, then there might be a pit the size of a nickel to quarter as the largest...most are size of a pea.
Finally, is there anything I can do to prevent or slow-down the future molding process? The widest areas are maybe 1/8" and a but wider where the travertine butts up to the foundation.
Thank you and pls let me know if you have any questions?
