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.


Installing Epoxy Novolac #633

February 22, 2016

Epoxy.com Product #633 Novolac Epoxy Coating is installed basically in 3 Steps.

  1. Properly prepare the substratemixing-Epoxy
  2. Apply 1 coat of Epoxy.com Product #899 Primer at a rate of 250 to 300 SF per gallon per coat.
  3. Apply 2 coats of Epoxy.com Product #633 at a rate of 160 to 200 SF per gallon per coat.

Product #899 Epoxy Primer and Product #633 Coating are mixed and applied the same way. These are the only differences:

  1. The spread rate
  2. The optional anti-skid is typically only added to the #633

For the sake of simplicity the procedure for mixing and installing is mentioned once below because the three coats apply virtually the same way.

Before You Start

Before you start you will want to read the following.

  • Do with Epoxies – The things that you don’t want to forget to do when using epoxy.
  • Don’ts with Epoxies – Don’t do any of these things when using epoxy.
  • Surface Preparation – Surface preparation sets the foundation for your application. If you want your job to work better and last longer be sure to read and follow these steps.
  • For a list of job supplies to install a chip flooring see www.epoxy.com/job-supplies.aspx
  • Be sure to mix both the A and the B sides of your material before starting. Be sure to use a clean stir stick or mixing paddle for both. Do not cross contaminate.

Optional Cove

Cove Base Installation – Epoxy Cove installation used to be very difficult to install. With Epoxy.com Products and this installation guide, this job is made much easier.

Primer

When installing over concrete or wood you will first want to prime with Product #899 Epoxy Primer –www.epoxy.com/899.aspx. The purpose of this primer is to go on thin (250-300 square feet per gallon) and seal the floor so you do not get air or moisture coming up into your epoxy coating which will be going on thick (160-200 square feet per gallon). The 899 epoxy primer is also thinner than the coating and so it flows out better. Over stainless steel, aluminum and galvanized metal use Epoxy.com Product #660 Aluminum Filled for the primer.

 

MIXING INSTRUCTIONS

 

Mixing is by far the most important part of installation. One method to insure accurateEpoxy_Measure_2 mix ratios is to put measurements on sticks with the appropriate mix ratio. In the case of the 899 and 633 this is 2 Parts A to 1 Part B, so you might do 3 inches “A” to 1.5 inch of “B”

It is sometimes helpful to put some duct tape on the A stick. It will help you to see your line when using the pigmented “A” side

Be sure to properly protect the floor where you will be doing your mixing.Epoxy_Measure_1

Stir the Resin “A” and the Hardener “B ”each separately in their original container before measuring and mixing the two together. Be careful to use separate stir sticks so not to cross contaminate.

Temperature of Epoxy.com Product #899 Primer and Epoxy.com Products #1, #2 and #633 must be 50 degrees F or above at time of mixing. Stir each component separately before blending. Mix two parts by volume of Part A with one part by volume of Part B for three minutes with a low speed electric drill motor equipped with a mixing paddle. Be sure the mixing paddle is large enough to mix the material completely.  You will want to use a “propeller” type mixer with blades 5 inches or bigger.

Preparing to Mix Resin and Hardener Together

  • A 5 gallon metal pail or 5 gallon plastic pail makes a great mixing110614_2044_EpoxyChipFl10.png bucket.
  • Always be sure that your mix bucket is clean and is not contaminated with anything before you mix.
  • Some people like to use the two bucket method. That allows your person mixing to be mixing while your install people are installing the last bucket.
  • If you start to show signs of your material hardening in the mix bucket, start using a new one.

Mixing Tools

  • Typically you will want to use a paddle mixer, that goes into a low speed drill.
  • Your drill mixer should be large enough to stir the entire batch at once. A mixer that only moves only the partial contents of the pail, may result in inadequate mixing. Be sure that you use a clean mixing paddle. A dirty mixing paddle can result in poor mixing or contamination of the batch.
  • When mixing try not to whip any unnecessary air into your mix, by using the slowest drill speed and keeping the mixing paddle reasonably level.

Mixing110614_2044_EpoxyChipFl7.png

  • Carefully measure out the “A” resin and the “B” hardener into two other containers.
  • Pour “A” resin into your mixing bucket and then pour the “B” hardener into the mixing bucket. Always pour the “A” first and then the “B”
  • Stir for 3 minutes, being sure to scrape the bottom and sides as you mix.mixing-Epoxy

If Anti-Skid Course or Anti-Skid Fine is to be used add 12-16 volume ounces per mixed gallon, and mix until properly dispersed, typically 1-2 minutes.

Doing the Trim

• Trim around all the areas that are difficult to roll.

• Remember not to get two far ahead, you don’t want the material to set up before it is 110614_2044_EpoxyChipFl14.pngbroadcast.

• Also remember to pull the duct tape while the material is still wet

APPLICATION

Epoxy.com Product #899 can be applied with a brush, roller or squeegee at a rate of 250-300 square feet per gallon.  Remember that if you put it on too thick you can get bubbles in the 899 Epoxy Primer. The important thing is to 110614_2044_EpoxyChipFl17.pngcompletely wet out the concrete without leaving excessive material. Allow the 899 primer to cure until hard.  Typically, 10-12 hours at 75 degrees F.  Do not allow more than 24 hours between this coat and the coat of coating to follow it. Epoxy.com 899 Primer typically requires only 1 coat.

The Epoxy.com Product #633 Novolac Epoxy Coating is typically applied at a rate of 160-200 SF per gallon per coat. Typically, 2 coats of Epoxy.com Product #633 High Chemical Resistance Epoxy are required. These coatings can be applied with the same tools as #899 Epoxy Prime.110614_2044_EpoxyChipFl20.png

When Product #633 is applied over concrete or wood, prime with Product #899 Epoxy Primer and allow the Product #899 Primer to cure to tack free. Over stainless steel, aluminum and galvanized metal use Epoxy.com Product #660 Aluminum Filled for the primer. Be sure to install the 633 within 24 hours of the installation of the primer.

For typical installations as a coating apply 2 coats of Product #633 Novolac Epoxy at a rate of 160-200 square feet per gallon per coat. This yields a wet film thickness of 8-10 mils thick per coat or 16 – 20 mils for the two coats. Since this is a 100% solids Resin and Hardener system, there is no loss during drying, so the wet film thickness and the dry film thickness for 2 coats will be identical (16-20 mils DFT). Be sure to install the second coat after the 1st coat is hard enough to walk on but before 24 hours after the installation of the previous coating.

If Anti-Skid Fine or Anti-Skid Course epoxy anti-skid additive is used add plus or minus 12 volume ounces of Anti-Skid per mixed gallon of Product #633. Never add more than 16 volume ounces per gallon of Resin and Hardener mix.

In summary:

Step 1. Good Surface Preparation

Step 2. Apply 1 coat of Epoxy.com Product #899, at a rate of 250-300 SF per gallon

Step 3. Apply 2 coats of the appropriate Product #633 Highly Chemical Resistant Novolac Epoxy Coating. Add optional anti-skid if required.
