Epoxy Over Epoxy

June 28, 2016

A customer writes: “I installed your Product #1 All Purpose Epoxy Coating on our floor about 20 years ago.  The floor is not warn out or pealing.  It does have scratches where pallets with nails sticking out the bottom has scratched the surface. I want to change the color to our company color anyway, so I want to re-coat the whole floor. How do I proceed from here?”

You will want to sand the existing floor removing all the shine.  It sounds like there was quality installation and surface prep, since you have no lifting or pealing. If you should have any that is loose you need  to completely remove loose coating .  Solvent wipe with Xylene. Lets solvent dry and apply your epoxy normally.

CAUTION:  Epoxy doesn’t like sticking to epoxy unless you do your surface prep meticulously.  I always recommend doing a test patch to test your surface preparation before you proceed with doing the rest of the floor. This can be done by placing a small test patch or patches. Let them harden overnight and then try removing them with a putty knife, screw driver of similar method to insure it is well bonded.

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? Epoxy.com 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. Epoxy.com 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.

Epoxy.com 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 Epoxy.com 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 Epoxy.com Product #660 Universal Primer and Finish with excellent adhesion.

Advantages

  • 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 Epoxy.com 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.

Please contact Epoxy.com Technical Support Department at 352-533-2167 with your questions. Epoxy.com Technical Support is dedicated to making sure you have the right product for the right job.


Tombstone Repairs with Epoxy

August 22, 2012

A technician who uses a non-Epoxy.com product to repair tombstones wrote me recently looking for help with problems that he was having.  He goes on to say that the epoxy that he uses never fails, but rather the stone fails. When a secondary break occurs, the stone always re-breaks about 2 mm (about ¾ inch) above or below the epoxy joint.  The epoxy attached to about 2 mm of the stone and holds well.

He asked me if the epoxy shrinks so much that it will ‘ pull away ‘ from the stone it’s attached to, and in his case, it pulls about 2mm of stone with it.

No I doubt it is epoxy shrinkage causing the problem. High quality epoxy has little or no shrinkage.  It would have to be a very poor quality epoxy to be shrinking enough to do that.

The reason his epoxy is not working is that it is too rigid.  His existing rigid material has a “high modulus of elasticity”.  A material with “high modulus of elasticity” is a material that is stiff and/or rigid.  A “low modulus of elasticity” material is semi-flexible, and is not rigid or brittle.

Smaller pieces of the stone structure (in this case a tombstone) and pieces not in touch with the ground tend to get hotter and cooler faster than the larger pieces and pieces with ground contact. This is called “differential timing of the event”. For example the top of a tombstone can be heated and cooled on 5 sides, the top and the 4 sides. The base of the tombstone which is buried in the ground has earth or stone on all of its surfaces.  This earth and stone tends to keep the temperature of the base more stable by insulating it and slowing the change in temperature. This works much like the insulation in your house slows temperature changes inside your house.

When an object like a piece of stone is heated it expands (gets bigger).  When an object cools it contracts (gets smaller).  For example 100 feet of concrete will be 1 inch longer once it is heated 100 degrees F.  That is why expansion joints are cut into concrete.

In the case of tombstones all the pieces of the same type of stone have very similar if not identical “coefficient of expansion”. Since the pieces are positioned with potentially different timing of heating and cooling there is a “differential timing of the event” (see above). The result is stress areas you are seeing in the closest weakened plane in the stone near the bond line.

Product #2005  was specifically designed for tombstone (monuments) and/or stone bonding, or repair. Epoxy.com Product #2005 is very strong yet it is has a “low modulus of elasticity” (semi-flexible).  The low-modulus of elasticity helps to absorb differential movement (two sections of stone heating and cooling at different times), making it much less likely to cause a stress area in adjacent weakened planes.

Camouflage the bond line rubbing stone dust(ground off the original stone or a similar colored stone) into any exposed epoxy material while the epoxy is still “wet”. That way the dust will stick in the wet epoxy making the epoxy difficult to impossible to see.

Epoxy.com Splash Zone and Under Water Coating and Paste

August 19, 2010


Below are some of the questions that have been emailed to Norm Lambert at norm@epoxy.com and some of his answers.
Have a question for Epoxy.com?  If so, please email Epoxy.com Technical Support.

Patching and Coating With Epoxy.com Products at and Below the Water Line

Q: I am looking for a material that I can use to patch and coat a concrete seawall.  I need to repair areas where the salt damage has eaten away
the concrete, and protect the rest of the surfaces. The area I need to do is in the tidal zone.  I can clean up the concrete, dry it up (if I
need to) and apply the a material  during low tide, but the product will need to be either very fast setting or be able to cure under water when
the tide comes in.  What do you recommend?

Norm Lambert: First you will want to do good surface prepartion – www.epoxy.com/surfaceprep.aspx. Then you will want to use Epoxy.com Product #707 Splash Zone Coating and Underwater Paste is a moisture-insensitive, two-component, 100% solids epoxy-resin system. When mixed at a 1:1 ratio, by volume, this product produces a paste-like material that is ideal for protection or restoration of concrete, steel and timber piles and other structural elements in marine environments. It will easily do what you are looking to do and a whole lot more as well.

 Epoxy.com Product #707 Splash Zone Coating and Underwater Paste has a long pot-life, and is available in a
fast Cure.  Epoxy.com Product #707 Splash Zone Coating and Underwater Paste can be hand applied, above, at or below the water line. 
It resists wave action and will even bond to wet surfaces.

What Epoxy for a Mechanical Room Floor.

August 18, 2010

I have a concrete mechanical room floor that I want to install a waterproof coating over. It has areas under it that I do not want to get wet. Due to the vibration I want to be sure we have good crack isolation for the concrete floor as well as being waterproof. Which Epoxy.com Coating System do you recommend?

Norm Lambert:

1.Prepare the concrete properly – www.epoxysystems.com/surfaceprep.aspx.

2. If there are any random cracks, repair them with Epoxy.com Product #685 – www.epoxysystems.com/685.htm MMA Polymer Crack Healer & Sealer. This material will weld the cracks back together structurally, making it as though the cracks never happened.

3. Fill any saw cut relieve joints with Epoxy.com Product #11 – www.epoxysystems.com/11.htm 100% Solids Epoxy Joint Filler.

4. Cold joints can be saw-cut and filled with Epoxy.com Product #11.  If cold joints are large enough, saw cutting may be optional.  Or if the cold joints are to be non-moving you can fill them with Epoxy.com Product #685.

5. Install 1 coat of Epoxy.com Product #899 –  www.epoxysystems.com/899.aspx  –  100% Solids Low-Mod Low Viscosity Zero (0) VOC Epoxy Primer at a rate of 250-300 SF per gallon per coat. Allow to dry overnight.

6. Install 2 coats of Epoxy.com Product #32 –www.epoxysystems.com/32.aspx – Epoxy.com Product #32 100% Solids Flexible Epoxy Membrane – Crack Isolation Epoxy. Allow to dry overnight after both coats.

7. Install 2 coats of Epoxy.com Product #2 – www.epoxy.com/2.htm – 100% Solids Epoxy Based Chemical Resistant Coating with an optional Epoxy Product#50 (small) or Product #51 (large) Anti-Skid additive. Epoxy.com Product#50 and #51 are polypropylene beads that mix with your Product #2 to produce the desired Anti-skid.
