To ensure best performance, DO NOT COAT IF THE FOLLOWING CONDITIONS EXIST:

Sealed concrete - Determine if there is a concrete sealer present by dripping a small amount of water onto various areas of the surface. If the water beads, a sealer is present and paint may not adhere properly.  To remove sealer and be able to coat your floor you must use a floor grinder or shot-blaster to prepare your floor.

Poorly-bonded previous paint - If the floor is previously painted, remove any loose paint by sanding and scraping.

NOTE: If you have a moisture problem in your slab, do not use this epoxy or any other type of paint! If unsure about moisture in your slab, duct tape on all four sides a 4'x4' piece of plastic to the slab. Let sit for minimum of 24 hrs. If moisture is present under the plastic then your slab is unsuitable for painting or coating. If moisture is present and you still want to coat the floor then a primer coat is highly recommended but not guaranteed.

WARNING! If you scrape, sand or remove old paint, you may release lead dust. LEAD IS TOXIC. EXPOSURE TO LEAD DUST CAN CAUSE SERIOUS ILLNESS SUCH AS BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD ALSO AVOID EXPOSURE. Wear a NIOSH-approved respirator to control lead exposure. Clean up carefully with a HEPA vacuum and a wet mop. Before you start, find out how to protect yourself and your family by contacting the National Lead Information Hotline at 1-800-424-LEAD or log on to www.epa.gov/lead.

Loose or poorly cured concrete or concrete dust - If the concrete is loose, chipping (spalled), or has concrete dust present, the coating will not perform properly unless

                                         SURFACE PREPARATION

Preparation is critical.  And yes, it is possible to have a successful long lasting durable floor without doing a whole lot.  BUT WHY TAKE THE CHANCE!  If you can rent a grinder do it.  If not, it is highly suggested the you at least degrease and acid etch the floor.  Many people ask, in one way or another, if preparation is minimal is there a system or epoxy which is better than others?  Answer is yes, at least use AD134 primer before applying the AD77 then top coat with AD311. 

Surface preparation is often a judgment call based upon the location, condition and history of the existing concrete. Perhaps the surface needing the least preparation is the typical cement sidewalk outside your house that has been 'weathered' for several years and has never been oil stained, painted, etc. The existing garage, factory or other work floors are the floors that should cause the most concern. Waxes, sealers, spills, dissolved salts, are all possible problems awaiting.
