We offer a range of thickened epoxy products. They are used to fill gaps - spaces - voids, fair, bond and glue. Our WET DRY 700 epoxy cream can be applied and used underwater.

Should you just thicken 'regular' epoxy with fillers

or purchase pre-thickened epoxy?


MAKE YOUR OWN: There are several different fillers - thickeners that you can add to epoxy. Many professionals like to use a combination of fillers and thickeners worked out over years of experience. The mix can vary with the specific application depending upon the results required. We sell a wide range of fillers and thickeners for both marine and non-marine applications (perhaps more options here than anyone else). Also, by making your own thickened epoxy you can control how thick the mixture becomes.

DOWNSIDE: 1) you cannot mix in these fillers and thickeners the way the factory can with high speed blenders etc.

2) it takes a lot of fillers and thickeners to thicken epoxy. It surprises people to discover that it takes about 2 quarts of fillers/thickeners added to 1 quart of epoxy to make just over 1 quart of thickened epoxy. That is 8 quarts of thickeners per gallon of epoxy. These products sell for about $8 to $15 a quart. That's a lot of money for a good sized batch of thickened epoxy!

3) shipping for a few quarts of fillers and thickeners is usually expensive - it can cost more (US mail or UPS) to ship than the price of the product. The only way around this is to purchase epoxy as well and let the thickeners sort of "ride free" shipping cost-wise with the epoxy.

Jeff (1/2013)   I cannot believe how incredible this Wet Dry 700 is. It's revolutionary. The original repair to my storm shelter would have lasted years if the shelter would just stop shifting around in the ground. DON'T STOP SELLING THIS STUFF.

 (10/2013)     Comments: Returning  -  Underwater boat repair - My third or fourth order and am still quite pleased with the result. It has many uses above and below the water line.

"The Wet Dry 700 epoxy paste worked great for patching for the rotted dingy transom. I cut out the rot, fitted new oak pieces, and patched with the Wet Dry 700 epoxy. Easy as pie." -- John 1/15

"I'll stick with my original plan to use the Wet Dry 700 since it's a nuclear reactor application, and I know of two other reactors that have successfully used it" - Jeff 12/16

Wooden Boat Forum - 3/16: "The stuff mentioned is Wet Dry 700... Among other things, I rebuilt a coffee mug handle, filling a gap in the handle where the ceramic was shattered. The repair has survived hundreds of trips through the dishwasher, a hot, wet, strongly alkaline temperature cycle test that will destroy most of the epoxies we use. If I ever need a really hard, chemical and heat resistant paste epoxy, this is high on my list."

Epoxy Cream




Creamy yellow epoxy used for non structural fairing and filling of holes and voids. Unlike other thick epoxies it slides off a putty knife like a hot knife through butter without pulling or tugging the epoxy behind it. Stays somewhat soft for several days.

Available in 1.5 quart and 1.5 gallon units.

Crack Coat



Dark Gray smooth and slick epoxy. About as thick as toothpaste. Uniquely flexible and will bend and move. Use on surfaces that need some "give" due to expansion and contraction, vibration, etc. Good for 'bedding' objects down. Can be applied on damp surfaces.

Available in three quart units.

Splash Zone A-788



The 'Granddaddy' of thick epoxies and underwater epoxies. About chewing gum thick - so thick it needs temps over about 60 degrees to even come out of the can.

Available in two quart and two gallon units.

Thickeners and fillers include:


micro-balloons in 2 sizes (slightly finer/small than what the competition offers, and SUPER fine)

fumed silica - super light (so light it can be hard to blend in) - the most common epoxy thickener

EZ thick - very fine cellulose powder (very popular)

wood flour - very fine wood (mostly pine) powder (very polular)

poly fiber - small strands of fiber to internal re-enforcement of epoxies - generally mixed in with other thickeners

walnut shell grit - non slip additive in three sizes
