Epoxy Mortar Installation

June 19, 2019

Epoxy.com Mortar Systems can be used to make permanent repairs that no other kind of product can make. The purpose of this blog is to give you an overview of what you can use and how to use it.

  1. Product Selection –  The following are a list of Epoxy.com Products that make excellent epoxy mortars  All the products listed below are zero (0) VOC, so it meets even the strictest low VOC requirements, and meets Indoor Environmental Quality/Air Quality (LEED IEQ 4.2 Indoor Emitting Materials Credit). See the individual product component technical data sheets and MSDS for further information.
  2. INSTALLATION:
    • First and foremost is good surface preparation.  Good surface preparation is necessary for most if not all patches to have long term success: www.epoxy.com/surfaceprep.aspx.
    • Prime the bottom of the whole with some of the neat mortar resin. Neat mortar resin is the liquid (A&B) mixed at the proper mix ratio and stirring in a way to insure a completely mixed product.  This will typically take about 3 minutes.
    • Mix some of the neat epoxy into the Epoxy.com Mortar Blend Aggregate #82 or other appropriate dry clean silica sand gradation.
    • The amount of sand aggregate depends on the aggregate used. 
      • Typically, the Epoxy.com Product #82 Mortar aggregate can be added at a rate of 18 to 27 lbs. of #82 per 1.5 Qt of mixed resin (1Quart of A to ½ Quart of B).
      • You will need to recalculate the sand above when using a different sized batch. This is doubly true if using one of or 4:1 mix ratio material.
      • Shallow patches tend to be a smaller amount of sand filler.
      • Deeper patches tend to be on the higher side.
      • If you get a lot of resin to the surface your mix is too wet.  If your mixture after it hardens is porous, or weak then you have added too much aggregate.
      • For a better finish in very deep pours do it in 2 lifts. 
        • Fill all but the last ¼ inch plus or minus with your dryer mix. Allow to cure hard (typically overnight).Fill with a wetter mix on top of that after the first one has cured.
        • To ensure proper adhesion between layers never wait more than 24 hours between layers.
      • It is always better to have your patch slightly higher rather than to low.  If you are slightly high you can grind the patch back to level. If to low you will need to fill again. 
    • For very shallow fills (1/32 or so) where the sand particles are to large you can use any of the following:

Seamless Epoxy Flooring Systems Explained

August 15, 2016

Epoxy.com offers many different types of seamless flooring. We offer so many kinds that sometimes it confuses people. The purpose of this article is to explain the differences, and to help you choose the right epoxy seamless flooring system for your application. In some cases the right seamless flooring system will not even be an epoxy. It may be polyurethane or Methyl Methacrylate (MMA).

Epoxy.com Epoxy Chip Flooring in VT rest area.

Epoxy.com Epoxy Chip Flooring on a VT Interstate Rest Area – Taken over 15 years after installation.

Epoxy Floor Coatings

Epoxy coatings can be effective flooring systems. When choosing epoxy as a flooring system choose a 100% solids (zero VOC, hard durable coating. You also want a coating that is available in multiple colors. These floor coatings can last for decades, so you want to pick a color that you like. Properly installed you will be looking at this floor coating for a very long time. This kind of flooring system is available in the following options:

  1. Epoxy.com Product #1 – www.epoxy.com/1.htm – meets all the criteria above. It has good chemical resistance, and excellent cost to benefit ratio. Great for warehouses, in areas with high traffic and only modest chemical exposure.
  2. Epoxy.com Product #1ESD – www.epoxy.com/1esd.aspx. This is the same as product #1 above but has conductive filler in it. Depending on the primer you use under this system it can be conductive (100,000 – 1,000,000) ohms of resistance or Electro-Static Dissipative (ESD) which is 1,000,000 to 1, 000,000,000 ohms. Used in plants that produce explosive materials like ammunition, fireworks, flairs, or explosive solvents, and used in areas of sensitive electronics, like computer server buildings, avionics, electronics assembly and electronic production areas.
  3. Epoxy.com Product #2 – www.epoxy.com/2.aspx. This is similar to product #1 but with a much higher chemical resistance. This major increase in chemical resistance is offset by only a small increase in the cost of the #2 over the Product #1. The product #2 is well suited for applications like garages, machine shops, sewer tank floors, battery rooms, cooling towers, grooming shops, dog kennels and all areas where an economical chemical resistant coating is required.
  4. Epoxy.com Product #633 – www.epoxy.com/633.aspx – is a highly chemically resistant epoxy floor coating and flooring system. Like Product #1 and Product #2 is extremely durable. Product #633 is typically used in areas where containment of aggressive chemical is imperative. For example Product #633 will hold up to continuous exposure of 98% Sulfuric acid for a period of at least 6 months without loss of structural integrity. Great for secondary containment for a large number of chemicals.

     

All the systems above can go over many different types of substrates with the proper surface preparation. All of the products above are available in 17 colors and can be color matched for an additional cost. The systems above can be combined with various anti-skid materials or broadcast with silica broadcast aggregate to produce a thicker floor.

 

Chip Floor

Epoxy.com Chip Flooring – www.epoxy.com/chips.aspx – is the perfect blend of economy, durability, low maintenance, and gorgeous appearance. It uses a 100% solids pigmented epoxy base coat, a full broadcast of plastic chips, and two coats of chemical resistant clear glaze. The chemical resistant glaze also makes this easily the most non-yellow epoxy top coat available today. This easy to clean chip flooring system is best for high traffic areas where appearance, durability and low cost of ownership is a must. Chip Flooring is great for commercial and residential kitchens, bathrooms, showers, grooming shops, kennels, veterinary clinics, garage floors, show rooms, rest areas, and much more. This product can be installed with an integral cove base. Epoxy.com Chip Flooring can be installed by a contractor but easy enough to be installed by a home owner. Epoxy.com Chip Flooring can be installed in a residence but is rugged enough to be used in the most demanding commercial applications.

Quartz Flooring

Quartz Flooring Product #15 – www.epoxy.com/15.aspx has a long history of being durable, attractive and non-yellowing. I personally installed this product on high school bathroom floors in the mid 70s. These floors have held up to the test of time with little or no wear, little or no loss of shine and little to no yellowing even under the urinals. This is also available with an integral cove base

Solid Colored Flooring

These solid colored floors are based around self leveling, trowelable or double broadcast application techniques. These floors are sometimes called shop floor. They are made to be thick and extra durable under extremely harsh environments. They can be top coated with any of the systems above under coatings. This kind of flooring is available in 3 speeds of cure: normal, fast, and cold cure. Solid colored flooring is also available with an integral cove base.

Methyl Methacrylate (MMA) Flooring

The big advantage of MMA is speed of curing. Each coat of MMA will cure hard to the touch in 1-2 hours. This allows the next layer to be applied quickly and traffic to be returned to it quickly. You can even build a fast setting integral cove out of MMA resin.

I personally installed MMA on many floors with very tight schedules. One restaurant was only closed for breakfast. The project started with rotten plywood floors. At 10 PM the carpenters came in to work. They removed rotten floor and floor joists. They replaced the floor joists and the plywood. At 5 AM we went in with the flooring installation crew.  We primed the floor and sealed up the joints in the wood and the screw holes. At 6:30 AM we laid the floor. At 8 we put a glaze coating on the floor and by 10:30 the restaurant workers were on the floor prepping for lunch. The floor installation from start to traffic took just 5.5 hours.

Polyurethane Decking Systems

Polyurethane Decking – http://www.epoxy.com/elastomeric.aspx – is the system best used in areas where maximum flexibility is necessary. This is typically outdoors, waterproof applications like balconies.

Specialized Flooring

We have a number of systems that are specialized flooring like conductive and ESD (Electrostatic Dissipative) flooring – www.epoxy.com/conductive.aspx – and various hybrid systems. If your project does not seem to fit in the categories above email me at norm@epoxy.com or call us at 352-533-2167.

 

In conclusion we offer many types of seamless flooring systems, they can be used for commercial and residential applications. These systems are durable, economical, and easy to install even by homeowners. These seamless flooring systems may be made out of epoxy, polyurethane, or methyl Methacrylate (MMA). Seamless flooring systems are available in multicolored or solid colored. They range in chemical resistance from very good to resistant to aggressive chemicals.

Patching Vinyl Ester Floors With Novolac

July 28, 2016

A customer writes:

“We have a dairy processing and packaging facility that was built circa 1994.  At the time of construction we chose to install a flooring system which was vinyl ester based with fiberglass mat.  The floor has held up quite well in areas where it had a good bond.  The failures we have seen are in areas that covered either an expansion joint or control joint in the concrete.  In these areas the flooring has delaminated from the concrete.  Where possible we have made a clean cut through the flooring to an area where we had a good bond and left the concrete exposed.  Other failure areas are around floor drains.  We have made repairs with quick curing epoxies in the past but these don’t seem to bond well to the existing vinyl ester flooring. 

“Having a manufacturing facility with only one down day limits our ability to make substantive repairs.  During a search for low or no VOC  flooring systems I you folks.”

I have personally made many thousands of square feet of floor repairs that sounds exactly like the issues and conditions that you are describing.

Here is what I did to permanently resolve the issue, at least in the patched areas.

  1. Cut back the edges of the delaminated areas back to a point where the vinyl ester is well attached.
  2. Prep the concrete under the failed area and the edges of the old material – epoxy.com/surfaceprep.aspx.
  3. Prime with Epoxy.com Product #12 – epoxy.com/12.aspx
  4. Install a trowel coat of Epoxy.com Product #630 – epoxy.com/633.aspx and
    1. Epoxy Mortar Blend aggregate #82 Mortar Blend Aggregate
    2. Allow to cure hard to the touch and cool.
  5. Glaze with a neat coat of Epoxy.com Product #633 with optional Anti-skid – http://epoxy.com/non-skid-additive-polycarbonate-aggregate.aspx

Choosing Stone for Epoxy Stone

May 5, 2016

Epoxy_Stone_OverlaysBonding stone together with Product #17 – Epoxy Stone Adhesive is attractive and functional. It allows you to have the look of natural rock. This “natural rock” will let water pass through it just like its non-epoxied counterparts. It is however a good choice when you don’t want that stone to be moved, accidentally or on purpose.

This function is so nice that I am seeing projects where larger and larger stone is being utilized for the same reasons (above) as the small stone. There are a few shortcomings that should be avoided when bonding larger stones.

You want to make sure when selecting your stone that it is not too round. Round stone reduces the square inches of surfaces touching each other that are bonded together. That reduces the strength of the material, by reducing the square inches of bonding surface. If angular stone is used (as in the picture above) you increase the surface area touching each other and increase the strength.

If you want larger stones in the mix, I suggest you use a variety of smaller stone to fill in the large gaps between the bigger stone. If you combine a mixed gradation of stone that is also angular (not round) you can get an excellent compromise of strength and large stone beauty.
