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:

Extending The Epoxy Install Season

October 17, 2017

Cold Temperature Epoxy

Installing Epoxy on Garage Floors in Cold Temperatures

Extend Epoxy Installation Season into Winter

It is that time of year again when I start getting  a lot of calls and emails about installing epoxy in cold temperatures. epoxy_color_chart_s

The best time to protect your floor is before it sees any salt at all. If you have a new garage floor now is the time to protect it.  It is still possible to do older floors but the more salt it sees the more difficult and expensive it can be.

The night temperatures are dropping this time of year. It is still possible to coat your garage floor before temperatures drop too low. Our cold temperature epoxies will cure with substrate temperatures as low as 35 degrees F, although it will set a lot faster at 40 degrees F.

Protecting your garage floors is especially  important in areas that will see salt from roads or ocean spray.  You will want to protect your garage from the ravaging effects of salt deterioration. Without protecting your floor salt will damage your garage floor and make for very expensive repairs later if it is not well protected.

It is not too late to protect your floor even in cold climates if you move quickly now.  Without this protection your garage floor will not be as nice come spring as it is now.  The damage that takes place is not only aesthetic but structural.

Cold Temperatures Epoxies

Cold Temperature Cure Epoxy Resins allow installation to be done at low temperatures as low as 35°F., (although it sets a lot faster at 40°F) expanding your epoxy coating and epoxy flooring installation season. Epoxy.com Cold Temperature Cure Epoxy Resins can also be used in cold storage areas like food processing areas, where the temperature cannot be raised higher than 35° F or so. Normal cured epoxy typically requires 50°F or more.

Depending on how you mix the aggregate into the products below, they can be used as a mortar for overlays, or a grout for sealing between other hardened construction materials.

Commonly Used Cold Temperature epoxies

Product #1 Cold Temperature Cure Epoxy Coating is 100% solids and specially formulated coatings for cold temperature applications. Cold Temperature Epoxy Coating #1 is able to cure at temperatures as low as 35°F. It has Zero (0) VOCs. Since it has no VOCs, it has no solvent so it meets the strictest possible standard for a low VOC coating. It is often used in coolers and food preparation areas that require constant low temperatures. Product #1 Cold Temperature Cure Epoxy Coating is also frequently used in room temperature applications to meet super-fast cure, limited shutdown needs.

Product #10 Cold Temperature Curing Epoxy Mortar Resin – This product has a low modulus of elasticity (flexibility) and is Low Viscosity. The low viscosity allows heavy loading of the right fillers. The heavy filler loading helps not only to save money, but helps to maintain better thermal coefficient with respect to concrete and steel. The low modulus of elasticity prevents it from being brittle making it less vulnerable to thermal coefficient differences. It also gives it better impact resistance.

Patching Floor with Epoxy

July 18, 2017

Here is an outline of the procedure for patching with Epoxy.com Product #1 and Product #10.  Cold cure is identical but you should make even smaller batches and work even faster.

  1. Mix a small amount of the #10 (mix ratio 2A: 1B).
    1. Measure accurately and mix for 3 minutes with a proper size mixer.
    2. Typically very small batches less than a quart can be mixed with a stir stick.
    3. Larger batches should use a mixing paddle in a low speed drill or similar. Typically  mixing paddles are 5 inches or more in diameter.
  2. Apply a primer coat of #10 at a rate of 250-300 SF per gallon (typically done with a roller) to the substrate the mortar is to be attached to.
    1. Typically you will allow this to harden to the touch to make troweling into it easy.
    2. You can trowel into the wet primer in the case of small patches.
  3. Mortar Patch
    1. Mix another small batch of #10, using the methods in step 1 above.
    2. Add Product #82 Mortar Blend Aggregate to the mixed resin in 3a. You can add as much as 50 to 75 lbs. of mortar blend aggregate to a gallon of mixed #10 resin. If the material appears to wet you can add more, if it is too dry add less.
    3. Quickly trowel the patch into place.  Winter Cure Epoxy can set very fast in the bucket.
  4. Sealer Coat
    1. After the patch in step 3 has hardened, you can grind off any high spots and fill more material again if needed.
    2. Then seal the top of the patch.
  1. Product #10 is thinner than the #1, making it an excellent sealer for sealing up the patch.
  2. Alternately you can go directly to a very thin coat of #1
  1. Top Coat
    1. Mix small batches of #1 using the methods used in #1 above.
    2. Mix optional Antiskid fine into the coating above at a rate of 8-16 volume ounces of Anti-skid per gallon of mixed resin.  12 ounces per gallon is typical.  This is done by mixing the resin first, adding the anti-skid and mixing for another min.
    3. Quickly apply the material with a roller at a rate of 160-200 SF per gallon per coat.  Two coats is recommended.

Secondary Chemical Containment

February 7, 2017

You can easily build containment in the middle of an existing slab

Building a secondary containment structure in the middle of an existing facility is very common and effective way to protect the facility structurally as well as protect the environment.  It is very easy to do.  Here is how:

  1. Grind the area where the curb will go to bare concrete – www.epoxy.com/surfaceprep.aspx.
  2. Drill holes into the concrete and fasten #4 bar into the concrete with Epoxy.com Product #2006 – www.epoxy.com/2006.aspx – Gel Adhesive. Allow Epoxy to cure overnight.
  3. Form the area to receive concrete curb.
  4. Coat the floor area in the bottom of the forms to receive the concrete for the curb with Epoxy.com Product #2007 – https://www.epoxy.com/Epoxy_Fresh_Concrete_to_Hardened_Concrete_2007.aspx – Wet to dry concrete adhesive. Pour your concrete before the #2007 becomes tack free. That will make it as if the curb and the concrete floor had been poured at the same time.
    1. An alternate method to this is to install concrete brick around the area bonding in place with Product #2006. This will help to reduce waiting for the concrete to cure if you use the poured concrete method above.
  5. Allow the concrete to cure – www.epoxy.comsurfaceprep.aspx.
  6. Cove the inside of the containment curb with Epoxy.com Product #720 – https://www.epoxy.com/720.aspx – coving resin allow to cure overnight.
  7. Prime the inside of the containment area with Epoxy.com Product #12– www.epoxy.com/12.aspx  – Chemical Resistant Primer, and allow to cure overnight.
  8. Install 2 coats of Epoxy.com Product #633 – www.epoxy.com/633.aspx – Chemical Resistant Novolac Epoxy Coating.

Summary

Doing an effective job of building secondary is easier than you may think. For more information visit our website at http://www.epoxy.com, call our technical support department at 352-533-2167 or email us at info@epoxy.com.

Installing Epoxy in Coolers and Cold Temperature

Extend Epoxy Installation Season into Winter

I have spoken on this subject here before but this time of year I get a lot of calls and emails about installing epoxy in cold temperatures. Our company started out as an installation company in Vermont. Summers are very short and winters are very long in Vermont. To stay a viable company, we had to figure ways of working through the winter.

Tenting and heating areas during the winter is time consuming and expensive. The solution is found in resin products that will set in low temperatures. The most durable and cost effective options of installation at cold temperatures is Epoxy and Methyl Methacrylate.

Cold Temperature Cure Resins can also be used as a super-fast setting Resinous Mortar or Coating at normal temperatures. Our Cold Temperature Cure Resins used at normal temperature give you quick turnaround time for small jobs, or larger jobs that require a short turn-around time.
