Dealing with the Elements…

Jasen,
Do you have recommendation for lime pops on brick? 1. Preventative 2. Correcting. Thanks, Kevin.

Hello, Kevin
Was this brick installed outdoors? I usually don’t like putting coatings on surfaces outdoors for this exact reason…Without the coating it would be fairly easy to remove the minerals with Easy Etch provided the bricks are clay and not concrete. There is actually no way to completely prevent this from occurring again, but using the product Preserve will drastically slow down the minerals from reappearing by reacting and hardening the stone’s integrity. With the coating present this will be a much more challenging project. You would need to first remove the coating and then remove the lime with the Easy Etch, followed with the treatment of Preserve. If they are looking for an enhanced (but not shiny) look, you can seal the brick with the Reveal & Seal within 20 minutes after applying the Preserve. I would not recommend re-coating this bricks especially since they have a history of mineral migration.
Hope this helped,
Jasen

Over Sealing…The Common Culprit

Jasen,
Yesterday I sealed an interior flagstone floor using a water based penetrating sealer. Today I got a call back from the homeowner saying that there are white blotches throughout. What could have caused this and what can I do to fix it?

Dave

Hello, Dave
Which sealer did you use? Those white blotches could have been caused by a reaction with the water and the minerals present int he stone, but most likely is the result of leaving too much sealer on the surface without properly wiping the excess. Mineral reactions typically take a while to build, so it wouldn’t be something that you’d see right away. If it is caused by excess sealer, use the product Modern Clean to remove it and rinse well. If the white areas are a form of mineral migration, you’ll have to use the product Easy Etch to remove them. Make note that Easy Etch is an acid product and can damage the stone’s surface if it is sensitive to low pH cleaners (most sandstone flagstone is not.) I’d suggest doing a test area to ensure that the cleaner will not damage the stone before cleaning the whole area.
If you have any other questions please feel free to contact me at any time,

Sometimes it’s just best to walk away…

Hey Jasen,

See pic below. They had a flood and it has damaged the marble. The floor is dry. It seems like the marble has completely absorbed the water. Have you seem this before? Is it fixable?

Hey, Noel
Do you know how long the floors have been dry? It could take days to dry up…this would be the best case scenario for a variety of reasons. First, if it is staining, chances are it has stained through out the entire stone. But even if it’s just on the surface grinding it out will prove to be very challenging. You’re right up on the wall so grinding it out evenly will be tough to say the very least…Also, that appears to be a Thassos White which means that it is one of the harder marbles to re-polish. If I couldn’t take it out with a simple poultice I’d most likely walk away from it…
