Selecting the Right Floor for a Mechanical Room

July 27, 2015

Mechanical Room Floors are very unique in their use and conditions. You have to consider the installation environment and the function of the floor. Our Mechanical Room Floor will protect the concrete, and contain any liquids that spill.

Systems used in mechanical rooms should be zero VOC. You do not want solvent evaporating from your material. Evaporated solvent could be picked up by your air handling unit sending it through your building. The best way to prevent this is with a VOC free 100% solids resin system. A resin system that is 100% solids has no solvent (or water) in it. It also means when you spread a gallon of material on your floor after it hardens you still have a gallon of material. With water-based and solvent based materials you lose half the material to evaporation.

Mechanical rooms should be chemical resistant. Typically they are top coated with Product #2 Chemical Resistant Epoxy – If it is a chemical feed room you can supply a list of chemicals and concentrations to the technical support department so you can make sure the #2 is chemical resistant enough.

The systems used for mechanical rooms are impact resistant. The limiting factor is the strength of the concrete substrate. Properly installed the epoxy will stay bonded to the concrete. The only way the epoxy can chip is if you chip the concrete from underneath the epoxy. You can install a thicker epoxy floor for an additional cost if you think you need still additional protection.

The systems recommend for mechanical rooms are highly abrasion resistant and will easily handle traffic up to heavy fork lift traffic. The system can be made even thicker if you have an unusual amount of abusive traffic.

When the mechanical room is over a finished space, it is suggested that a crack isolation membrane be integrated into the system. This can be done with Product #32 Epoxy Membrane System. The advantage of #32 Epoxy Membrane Resin as part of the system is 100% solids and has zero VOCs.

If the mechanical room is shut down and you can handle solvent and want something still more flexible you can use Product #459 a two component, high solids, elastomeric urethane instead of or in addition to the Product #32 Epoxy Membrane above. Product #459 exhibits excellent elongation properties along with high tensile strength and tear resistance to make it an ideal crack resistant membrane for use under Product #2 and all of our other epoxy mechanical room floor coatings.

One of the primary reasons you need a mechanical room floor over finished space below is to waterproof it. The above methods accomplish the waterproofing in the center of the floor. The edges of the floor can be protective with a coving material up the wall and around pipe penetrations. That can be accomplished with Product #720 Epoxy Coving Resin System which can be used to install an integral cove base for all of our epoxy based mechanical room flooring and most of our other epoxy flooring and coating systems. This provides seamless wall to floor protection.

Introducing Universal Steel Primer Coating #660

July 10, 2015

The problem with getting superior adhesion to difficult to bond to surfaces like stainless steel and aluminum has been solved


The Technical Support Department here gets many calls from people needing help in selecting the right coatings for a variety of metals and difficult to bond to surfaces. Carbon steel is easy to bond to when it is well sandblasted and you use one of our high end epoxy coatings like Product #2 Chemical Resistant Epoxy. What if the carbon steel cannot be sandblasted and can only be ground? What about stainless steel and other difficult to bond to metals and coatings? Product #660 Universal Primer and Finish was designed to solve these bonding issues.

Product #660 Universal Primer and Finish is a one component, moisture cured polyurethane aluminum filled primer and coating. Product #660 Universal Primer has a low viscosity, with high “wetting” characteristics, and blistering resistance. This makes Product #660 Universal Primer and Finish a superior primer. It can also be used as a finish coat. Product #660 Universal Primer and Finish undergoes a rapid molecular weight change as it polymerizes into a high molecular weight finish with excellent corrosion and abrasion resistance. Product #660 Universal Primer and Finish is an ideal barrier coat when upgrading existing finishes to strong urethanes, coal tar epoxy, etc. The low solvency power of Product #660 Universal Primer and Finish enables it to be applied over most types of coatings without causing lifting. A test sample should be made to confirm adhesion. Most generic types of chemical or conventional coatings may be applied over Product #660 Universal Primer and Finish with excellent adhesion.


  • Excellent primer for all types of surfaces.
  • Superior “wetting out” properties over sound, rusty steel.
  • Can be recoated in 1 to 2 hours and can be top coated with most generic type coatings.
  • Cures down to 25 degrees F on dry surfaces.
  • Service Temperature up to 400 degrees F
  • Corrosion resistant: Passes 12,000 hours in salt cabinet.
  • Good weather resistance.

Now with Product #660 Universal Primer you can bond to well sanded (ground) stainless steel, aluminum, and carbon steel that cannot be sandblasted. Product #660 Universal Primer is also effective in bonding to other difficult to bond to metals and many other hard to bond to coatings.

Product #660 can apply 2 coats and use it as a standalone coating. You can apply any of our 100% solids high quality epoxies or vinyl esters over it. The problem with getting superior adhesion to difficult to bond to surfaces like stainless steel has been solved.
