Our basement had mold in it, we have since corrected the problem and had the mold cleaned up. It was recommended that we seal the basement floor and walls to prevent excess water from entering the basement (exterior underground walls are already sealed). We have a home gym in the basement so are very concerned with respiratory health. What indoor concrete sealer would you recommend? and also plan on adding rubber flooring panels in the gym area.

Can this be used on the outside of concrete water troughs being used to grow aquatic plants? All sides of troughs are 3 inches thick. The concrete is fiber reinforced, unsealed and porous. The objective of sealing from the outside would be to reduce permeability/slow down water loss through the concrete. The sealer failing over time is not an issue for me. Or, is there another product better suited for this goal that will not change the look of the cured concrete? Thank you! 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

To add to my last question...can this sealer be used to seal Mapei Ultracolor Plus Max high performance, rapid setting grout? The grout says it has bio block technology but I don't know what that means. I want to make sure it can be used over the grout I used. Thank you!! View answer

What kind of adhesives would stick to this? I see that you can use thinset and tile over, but we are using a stone veneer product for our shower walls and need to glue it up. A two part epoxy adhesive is what is recommended by the manufacturer of the veneer. Would an epoxy based adhesive adhere to this product? View answer

Can I paint my old concrete basement floor with this? Does it require a primer? I have sealed small cracks that naturally form in the basement concrete through time. Our concrete was poured in the 70's and is still in good shape. Looking to make it look nicer. Not heavily used and will put throw rugs or carpet in areas over it. I am chemically sensitive. Will this work for our basement? View answer

Would this be a good replacement for epoxy on top of a slab, under a vapor barrier and engineered hardwood? The slab is fully dry (poured 2 years ago) and has a properly taped Stego vapor barrier so it should get minimal to no vapor. I just want to slow any additional vapor that might try to evaporate into the flooring. View answer

Is AFM WaterShield the right product to apply to the walls in a bathroom to repel moisture? The previous owner of my home had a bathroom (with shower) built, with NO fan to deal with moisture in the air when the shower is running. When I use this shower I use a window fan to push the moist air out, but, lots of moisture collects on the walls/ceiling in the bathroom. No issues with mold/mildew. How can I make these walls more hydrophobic so when the shower is used, the condensation that collects doesn't stick so readily, allowing the walls to dry more quickly after being wiped down. I will get a bathroom fan installed eventually but I want to add a water repellent on the walls (applied on top of the wall paint). Any product suggestions? View answer

The wall-to-wall carpet and padding in our lower-level living area developed a musty smell shortly after receiving six inches of rain within two hours. The carpet and pad were removed and discarded. The base floor is untreated concrete slab and we found no visual sign of mold, mildew or water entry on concrete slab or carpet/pad. Cleaning the floor with soap and water and running multiple dehumidifiers for 2 weeks eliminated the odor. We then applied Concrobium mold control (to be safe). We'd like to seal the concrete to prevent moisture vapor from migrating through the concrete in the future. The folks at AFM recommended using MexeSeal for this purpose. As you carry both MexeSeal and Green Building Supply Sealer. Which product do we use? View answer
