Should I patch cracks/holes/mortar joints prior to coating? How would I do this?Epoxy-Coat recommends patching all cracks prior to coating. Due to the fact that mortar joints/saw cuts are engineered for movement Epoxy-Coat does not recommend patching them prior to coating. Epoxy-Coat patch kits and caulk can be purchased online.
How would I coat Epoxy-Coat over wood surfaces?Simply remove sealers/waxes/contaminants/nails and use our flexible acrylic caulk to patch the seams and holes prior to coating. As long as the wood is clean and has a texture to it, the epoxy will adhere to it.
If I have fiberglass added to my concrete will Epoxy-Coat cover the little hairs that are present after floor preparation?No. Using a gas torch burn the hairs from the floor prior to coating Coat the floor with the first coat of Epoxy-Coat, wait 24 hours and sand vigorously.
When taping when should I pull the tape up?For ease or removal, remove tape between 2-3 hours after application at 70F
Should I add thinner to the coating when mixing?You may add up to 5% thinner to the mix for ease of application using xylene or MEK thinner only
How long does the standard coating take to apply, including preparation?Generally 1, but 2 days at the most. (In most cases.)
Does the concrete need to be cleaned before using the clean & prep solution?Yes, contamination must be removed.
Does crack/mortar joint patching crack or peel?All concrete moves. Mortar joints/saw cuts are engineered to allow for the movement of concrete. Cracks are the cause of more movement than the mortar joints/saw cuts will allow for. The coating will crack when the concrete moves but shouldn’t peel away from the sound concrete around the crack
Does the non-skid make the floor harder to clean?If you mop the floor, it will be harder. If washed with a broom, squeegee or power scrubber, there is only a slight difference.
Does the non-skid wear out?Yes, in approx. 5 years.
Should we put aluminum oxide nonskid on the floor in addition to the chips?If the conditions present water or oil, it is recommended.
Do the flake chips wear out?Generally, the flakes will outlast the coating.
What are the flake chips for?They help with non-skid and help hide imperfections in the floor by adding a decorative look.
Does the floor get slippery?Yes, when water or oil is present. Aluminum oxide non-skid is recommended to reduce this condition if you have excessive water or oil.
How long before the floor coating will wear out?Generally, Epoxy-Coat should be refreshed every 20 years.
How many square feet will a full kit cover?Up to 500 square feet at 9.7 mils Dry Film Thickness. Up to 240 square feet for 20 mils Dry Film Thickness. Most industrial floors apply at 16-20 mils Dry Film
If you have contaminants on the floor and therefore have fish eye problems what should you do?Re-roll the floor until the fisheyes go away and prior to flaking/ non-skidding the floor.
If you have bubbling problems during installation what should you do?Take a leaf blower and blow the top of the surface to remove the surface tension and removing the bubbles.
What temperatures can I apply Epoxy-Coat?40-90 degrees F.
How long do I need to wait to coat new concrete with Epoxy-Coat?30 days.
If I have new concrete will I need to prepare the floor as Epoxy-Coat instructions say?Yes. New concrete must still have a rough profile and clean surface prior to coating.
Can I apply Epoxy-Coat over an existing coating?Epoxy-Coat can be coated over existing paints/coatings by simply making sure the existing coatings are cleaned, sanded (80-100 grit) and bonding. All areas that are not bonding must be diamond ground.
Does the concrete need to be cleaned before using the clean & prep solution?Yes, if there is contamination it must be removed.
Are there any other special requirements for indoor applications?If your indoor floor, such as a basement concrete is in poor condition and needs to be prepped with a muriatic acid treatment, you will need a floor drain and ventilation. Muriatic acid does need to be rinsed down the drain and does produce some odors that must be ventilated.
Can I use Epoxy-Coat indoors and on basement floors?Yes, Epoxy-Coat is safe and approved for indoor use. There are no VOC fumes.
What do I do if the prep solution does not effectively profile my floor?You can purchase muriatic acid and re-etch the floor or diamond grind the surface.
How can I remove dried Epoxy-Coat from driveway concrete?We recommend using a safe paint stripper (home use). You can also use a power washer or handheld diamond grinder to remove this stripper.
Should I power wash my floor?It does help to power wash the floor to remove surface contaminants or loose coatings or debris. It does not eliminate the normal preparation steps, which we specify. Power washing removes contaminants but does not create the necessary profile for coatings proper adhesion.
With new or uncoated concrete, do I have to prepare the surface?Yes. You have to remove contaminants/latent and create a profile for the coating to properly bond. Shotblasting and/or Diamond Grinding is preferred for industrial, commercial and residential or institutional floors where the prep solution is ineffective.
Can my Epoxy-Coat be used for other surfaces other than concrete?Yes you can coat concrete, wood, tile or metal where direct UV exposure is not present.
