The exterior wall of our basement has been leaking for a few years when it rains. Black mold is appearing. This is not a dripping situation inside our basement but just a damp one. We spent a bundle last week on having our yard graded and it did nothing, sad to say. I'm looking to seal this wall very well (cinder block). Which product do you recommend? We want to go green. Thank you and thanks for creating these safer products. View answer

I have a wash and pack room on my small organic farm. The floor is concrete and needs to be sealed. It gets a lot of traffic daily and at least one day per week can have water on it for several hours while we wash vegetables (not underwater). The floor needs to not be slippery in any way. Is the Green Building Supply, Penetrating Concrete Sealer what I should use? I also have a walk in cooler with a concrete floor (insulated underneath). Can I also use this product with temperatures that remain between 37-43? Thanks! View answer

We have a tuck under cinder block/cement garage that is often moist due to seepage from the brick patio over the garage and water seepage into the underground walls. The walls have been painted, but are bubbling in places and in some places the paint is now gone and the block walls are crumbly. What is the best product to use inside the garage to seal out water, and prevent mold/mildew moisture. Is there a sealer that would help seal and prevent moisture from the brick patio from seeping into the garage? View answer

I am looking for a product that can be applied to a concrete, unfinished basement floor to slow/stop the seepage of moisture through the floor into the basement. The basement has never flooded, but shows efflorescence from moisture coming in through the concrete floor. Would the Penetrating WaterStop be a suitable product? View answer

Can this be applied over previously painted masonry where the paint has been partially removed (removed to the extent possible)? I understand it won't penetrate where there is still paint, but will it penetrate where the paint has been removed and it is down to raw brick? View answer

I plan on using microcement to cover my bathroom sinks, bathtub, and shower. Do I need different sealers for all three? I want a non toxic sealer especially for the bathtub, since your whole body soaks in it. I also need one for my kitchen counters and outdoors by surrounding my pool. I would like to minimize the number of products I need. Which ones do you recommend? View answer

I'm trying to slow moisture transfer, effervescence and dusting on brick basement interior walls. I've done what I can to regrade and drain outside but get moisture in the corners where there's old mortar/dirt between layers I think that don't dry well and show darker on the brick where it's been lime mortar repaired. (Like a sponged on german schmear.) Would this product be good for this application? View answer

Wow, you sure have a lot of paints to choose from. I want to coat some interior brick masonry with a neutral Navajo-type white semi-gloss. Trying to select both a primer and finish coat product. One gallon each should do. it's a pretty small area, about 100 sf. Want to minimize outgassing, have chemical sensitivity. Recommendations? View answer

Hello! This looks like a great product for our garage floor. What would you recommend for the garage walls (and basement walls)? They have not been painted in decades, have been known to get damp (even wet after heavy rainfall). Would you recommend sanding first (with what product), then priming (with anything in particular), and then painting? We'd like a product that is eco-friendly/non-toxic/low-VOC but that will also hopefully protect against moisture/mildew etc. Thanks very much! View answer

I would like to paint the ceramic tile floor throughout my home. The tile is glazed but is more on the matte side (not shiny). I cannot sand it, Would painting it with this concrete floor paint and then sealing it with AFM SafeCoat, Polyureseal B allow for a good bond to the floor tile and withstand our family of six walking on it? We do not wear shoes in the house, Please advise. Thank you View answer
