    Spartan Chems

    What is your answer?

    there can be moisture in the ground below the slab that is always evaporating. Even when a vapor membrane is installed below the slab, penetrations in the membrane may allow sufficient moisture to cause efflorescence. This moisture, invisible to the eye, is steadily traveling through the slab...

    What is your answer?

    This has happened to me. When applying dark grout, and the subfloor is concrete this will happen most times, sealer or not.

    VCT Problem - help

    To me it looks like spots of residue were left on the floor before laying down the finish, preventing it from adhering properly.

    Vinyl tile finish problem

    If its the first free you will probably be ok. I would try a test though before spreading it on the entire floor.

    no grains are the way to go. A plus side, is if you are eating less carbs you can eat more bacon.

    High gloss tile washroom floors

    Will antifreeze cause any harm to the solution lines and heat exchangers?

    We ship a lot of machines all over the country, and we always add RV antifreeze to the tank and run the pump for a minute to make sure nothing freezes during shipping. As long as the customer runs the machine for a few minutes with plain water it works great.

    High gloss tile washroom floors

    If it works ok with the autoscrubber but not a mop, that leads me to believe that the chemical you are mopping with is the problem. Are you using the same chemical in your autoscrubber? If so then perhaps your mops are dirty, or you may need to do a clean water rinse afterwards.
