Hello Sharon. Your floor would be great candidate for a densifier with siliconate sealer added. It works by helping to fill the pores in the concrete to reduce moisture from traveling up to the surface. In addition, the siliconate seals the surface to protect it from deicing fluids and salt damage. It needs to be applied in temps higher than 40 degrees. You can read more about this product and what we recommend here.

Hello Jennifer. It sounds like you have moisture that is coming up from below the slab. Mats do not breath and will block and collect moisture vapor, thus the wet concrete underneath. If you have slush running off the mat, then you need a containment mat. This will keep all liquids contained within the mat.

Hello Bill. The Kelly-Moore product will work OK, it but will need to be reapplied more often. The main ingredient is silane which needs to be applied in liberal amounts in order to soak well into the concrete for the best effects. Kelly-Moore counter acts this by using a sulficant to act as a water repellent on the surface, but it will wear away and doesn’t have a long life. We are not the biggest fan of silane for a garage floor, however. The reason is that the reactive chemical process of silanes are always looking for other chemicals to react with. If not enough is applied to the concrete, oil and gas (petroleum products) can react with the silane causing a permanent stain in the concrete that cannot be removed. We are not as familiar with their products so we can’t make a recommendation.

Siliconate sealers last much longer and will not have the same effect with petroleum products. Also a densifier and oil repellent combo such as this one works great as well.
