Ask a Question
  • how much product of 8505 silo-tek concentrated for 1400 square feet also do you ship to Vancouver island b,c, Canada (parksville is the city i live in)

    You would need about 10 gallons of ready to use, or 2 gallons of concentrate. 

    We can ship to Canada.

  • I would like to use the concentrated product. Please let me know the required number of coats. Also, how much would I need to buy to coat a 500 sf 20 year old concrete garage floor (496 sf to be exact). I am in the midwest with tough winters and road salts. Sealing out oil would be a bonus. I cannot afford the 8505 in my budget so I'm looking for an alternative cost effective solution.

    You are looking at 4 gallons total, so one gallon of 8505 concentrate would do it.   8505 or 8510 are the only options for oil stain resistance

  • I want to seal my garage floor because it has a basement underneath, can I use epoxy on top of Siloxa-Tek 8505 (or 8510) to make a more decretive finish but still have the water proof to keep moisture out of the basement underneath?

    Use of the 8505 or 8510 will unfortunately prevent the epoxy from adhereing to to the concrete so your finish wouldnt last long.  We do have an option for doing both, give us a call at 888-391-2227 and we can run through what we can do!

  • What is your recommendations for water sealer for a skate park? 8505

    8505 is a good choice.  8510 is probably the best sealer but maybe overkill for your application.  You can also look at Baracade Silane 40, or Baracade WB244

  • Can I add redi mix color to 8505 to provide color and sealing

    Siloxa-Tek 8505 is a penetrating sealer, not a surface sealer, so you are not able to add color.

  • Is this product safe for puppies and children????

    This is a penetrating sealer, so once it gets in the concrete, there are no concerns with puppies and children

  • how much quantity of concentrate 8505 to seal 1600 square feet floor

    YOU'LL NEED 11 TOTAL GALLONS: 2x 1-Gallon Concentrates + 1x 1-Gallon Bottle ready to use.

  • What products are compatible to apply over Siloxa-Tek 8505? Wife’s not happy that this product didn’t cover up the unevenness of our colored concrete.

    Siloxa-Tek isn't made for decorative concrete.  I would look in to the Cryli-Tek 5505.
