MAS Deep Pour Epoxy

Perfect for creating deep pour castings like live edge river tables and ocean tables—cures to a clear, glass-like finish!

Item #
94% of 100

MAS Deep Pour Epoxy is specifically designed for molding, encapsulating and creating deep pour castings, such as those used on live edge river tables and ocean tables. It cures slowly to a clear, glass-like finish that resists scratching and yellowing. The extended gel time minimizes exotherm and improves air release for the clearest possible results. For ocean and river tables, MAS Deep Pour is the epoxy resin to reach for.


  • Maximum casting thickness per pour is 1/2'' to 1'' at 70˚F (subject to multiple variables, consult the instructions for more info)
  • Thicker castings can be achieved with multiple pours
  • Improved air release for minimal air bubbles
  • Can be sanded and machined after 24-48 hours
  • Two-component system composed of 100% solids, with a 3:1 by volume mix ratio

IMPORTANT NOTE: This is an advanced deep pour epoxy resin system. DO NOT use Deep Pour Resin in working temperatures above 75°F. Please take into consideration the volume of epoxy you pour into a void. Pouring too much epoxy into a large area may result in shrinking, yellowing or cracking. Prior to using Deep Pour Epoxy, it is recommended that you seal any wood or porous surfaces with Penetrating Epoxy Sealer (#60727, sold separately). This will reduce the risk of air bubbles and foam during cure.

Do not apply oil based stains to surface prior to applying epoxy. Coating oil based stains with epoxy will result in surface imperfections and adhesion issues.

What is the coverage rate ?
ethicalbuild on Mar 24, 2020
BEST ANSWER: The 1.3 Quart size will cover approx. 300 sq in (2.08 sq ft) with a pour depth of 1/4". If the pour depth is 1/8" it will cover double that, 600sq in (4.16 sq ft).
why is my mas deep pour cracking during cure?
Edward M on May 16, 2020
BEST ANSWER: Epoxy is a mass and temperature sensitive material.  Use caution for very large pours. Pouring too thick and layering too quickly could cause the curing epoxy to heat up, yellow, distort or crack. The gel time (time it takes the mixed epoxy resin and hardener to initially harden up) can vary drastically depending on any number of factors such as mixing mass, material temp, ambient temp, mixing time, speed of mixing, speed of application, casting and coating thickness, etc.  MAS Deep Pour has a 5.5 hour gel time at 77°F in a 150 gram mass, but will set up much faster if warmer or left sitting for an extended time in a larger mass.  The more you mix up, and the warmer it is, the faster it will gel.  Curing epoxy is an ectothermic reaction.  If cured in too large a mass, epoxy will get too hot upon curing and could potentially distort or shrink or crack.  To minimize shrinkage, step pour thick castings and keep your project cool.  As a general rule, thinner castings of epoxy shrink less than thicker castings and you can then eliminate cracking.
what is the preferred type of dye to use with this product?
Matt P on Apr 29, 2020
BEST ANSWER: I talked to MAS technical support and they do not have a specific list of dyes that are compatible. They said that alcohol inks work as well as mica. In terms of dyes, I have used Transtint and Mixol on projects with other casting resins and they worked fine. The support person said sometimes even different colors of the same type dye perform differently. Their suggestion is to get the dye and mix up a small amount of resin to check compatibility. Never add more than 5% of the dye. If it is not compatible, you will see if clump up and not mix uniformly or be clear.
Can this be used oudoors?
Robert C on Apr 27, 2020
BEST ANSWER: MAS Table Top Pro can be used for exterior projects and furniture, but like most consumer products, Table Top Pro is not UV stable. Generally speaking, epoxy resin tends to yellow and may chalk when exposed to direct sunlight for extended periods of time, which is why they recommend protecting epoxies with a UV protectant varnish or paint for outdoor use. Marine grade polyurethane varnishes like Bristol Finish UV Clear, with enhanced UV protection additives, offer improved UV stability and abrasion resistance over “off the shelf” spar varnishes available at your local hardware store.
How long does it last/ Shelf life?
Alex on May 22, 2020
BEST ANSWER: The shelf life of MAS epoxy resins and hardeners is at least one year in sealed containers, but the material can last much longer when stored between 60-90°F in a dry place. The product should be stored indoors, on a raised surface off the floor and away from exterior walls.
will mas deep pour resin heat up and melt thru a plastic cup like the sealer did?
Edward M on Apr 29, 2020
BEST ANSWER: The deep pour resin does not generate as much heat when mixing so not sure if it would melt the cups you use. I would still use a more rigid plastic mixing container. You can try a small amount in what you were using but the more you mix, the more heat is generated.
Will this work for penblanks andbottle stoppers?
toolman on Apr 28, 2020
BEST ANSWER: If you are asking if Table Top and Deep Pour epoxy can be cast and turned for pen blanks and bottle stoppers, the answer is yes. They must be cured for over 24 hrs before being machined or turned.
I am looking to make some high-gloss finish wine goblets, and am looking for a food-safe, alcohol-proof finish. Will this work for that?
JamesWW on Apr 28, 2020
BEST ANSWER: I talked with the MAS technical support and they would not recommend using this for the application of a wine goblet. Table top epoxies are resistant to incidental contact with alcohol since used a lot on bar tops but they would not recommend using it as a drinking surface.
