Quick Buy -- BASIC NO BLUSH (tm) CLEAR MARINE EPOXY RESIN -- Now
Nearly all boat projects require multiple products: structural repair putties, fairing compounds, barrier coats, primers and sealers, laminating resins with fiberglass cloth and fillers. Generally people need help with product selection, amounts and application. No web site can give all this support, especially when so many things are involved. Our customers call 24/7 including nights, weekends and holidays for that kind of pre-purchase advice and application help. It is the only way to get a two way conversation to happen. 603.435.7199 EST

General Rules of Thumb (Based upon information for Interlux Boat Painting Guide)
Disclaimer: these are only theoretical suggestions based upon my knowledge of certain epoxy coatings. They are not vendor/manufacturer/supplier recommendations or approved techniques. Decision to follow or not follow these suggestions, rests completely with the purchaser or end user. There is no warranty, refunds, liability etc. implied or suggested regarding the selection, preparation, application, or results involving these products or suggestions mentioned here.
For the finest above the waterline hull coating (white only) I would recommend our LPU MARINE - a two-part linear polyester urethane (compare to Awlgrip) over a primed surface (we also have a less expensive white 2-part acrylic urethane now). For more information about epoxies and urethanes see our Chemistry of Epoxies/Urethanes page. For more info about LPU MARINE (WHITE ONLY) - CLICK HERE.
A standard 3 coat industrial system (zinc primer, epoxy, poly topcoat) - we do not sell a zinc primer product - poly coating not below the water line.
this is a common system for water towers, etc.
For the finest above the waterline hull coating (white only) I would recommend our LPU WHITE - a two-part linear polyester urethane (compare to Awlgrip) over a primed surface. For more information about epoxies and urethanes see our Chemistry of Epoxies/Urethanes page. For more info about LPU 100 - CLICK HERE. AVAIL IN WHITE ONLY.

Mix ratios/pumps - Most epoxy disasters result form mixing mistakes.
Some epoxies have more forgiving mix tolerances. Generally the closer to a 1 to 1 mix ratio the better. In these
cases being off a tiny bit is not so serious but with mix ratios of 1:4 or 1:5
Some epoxy companies like to sell inexpensive 'pumps' to measure out units of epoxy base and cure. I think it is more of a gimmick (and money maker). I would rather measure out the epoxy in disposable paper or plastic cups (two cups of A to one cup of B). Throw away the cups when they become 'messy' or even use new cups with every batch.
The pump issue came up on the WoodenBoat boatbuilding forum (11/19/01) "Temp and Epoxy Cure." Here's what was said about those pumps:
Repairing Hairline Cracks in old fiberglass hulls
All old fiberglass hulls seem to have them - lots and lots of tiny spider web like, gel coat cracks. These hairline cracks are ugly and can let moisture into the hull.
Here's my thoughts (and tests) on how to repair:
2) coat the area with our Aluthane aluminum primer. The very thin Aluthane will be drawn into the crack to help seal it and at the same time prime the surrounding fiberglass.
3) paint hull with a coat of our very brushable, 100% solids (0% VOC) Low V epoxy. This will actually cover the cracks and vanish them under a layer of epoxy.
4) sand the epoxy/hull smooth
5) paint the hull. If using our LPU MARINE polyurethane you'll need at least two coats to cover the aluminum color of the Aluthane.
No Sand Epoxy Surfaces
Epoxy will not stick to the poly bags we wrap our epoxy cans with for shipping. Simply apply the epoxy and evenly press the plastic across the wet epoxy and wait for the epoxy to harden. Then peel off the plastic.
Hello Paul Oman/Progressive Epoxy Polymers (epoxyproducts.com 603/435-7199);
Thanks for your advice and products. I stripped the hull with a 'green' paint stripper, sanded it with 120 grit, chipped old Bondo that had been used to fair the keel, re-faired the keel with your Wet Dry 700 epoxy kevlar (tm) putty, and then applied 2 coats of your ESP 155 epoxy primer, 2 coats of your CM 15 epoxy paint and 2 coats of Micron CSC with 1/2 ob of your copper powder per gallon of CSC. I also chased out the gelcoat cracks and filled with Wet Dry 700 epoxy putty. The hull came out beautifully.
I like working with your products. They are predictable and seem to hold to spec well. Your advice - even when I was half way through the job and made my 'lack of confidence call' (confidence in me) to you on a Saturday night was met with a quick call-back and clear map for success. I really don't know of any other supplier I would receive that from...
Kind regards -- Randall -- Mirage 35 (July 2015)
"Salvaged 45' sailboat. Purchased all my epoxy from you. I've been in the water two years and time to redo the bottom. Very happy with all the advise and delighted with how good the bottom held up. Started with 155, epoxy cream, `155 and three coats of Cm15 for barrier coat." MASON 11/16
One of our marine epoxy competitors (now a mere impersonal, product line sub-division within a big industrial corporation) claims a 30% savings in time using non blushing marine epoxies. Non blushing marine epoxies do not require washing or sanding between epoxy coats or top coating with other paints. Note that we offer Basic No Blush marine epoxy with fast, slow and regular curing agents (and it also includes bubble breakers for a more perfect finish). Our Premium No Bush epoxy is Nonyl free and uses an special curing agent is can be air shipped (shipped without restrictions).
Epoxy Crazing Notice/Warning
There are two types of Marine Epoxy Vendors: 1) discount, bulk, REPACKAGERS who simple buy drums of raw resin and raw curing agent(s) from the big chemical companies and fill plastic jugs for resale; 2) FORMULATORS take the raw epoxy chemicals add to them to enhance and improve the raw "moonshine" into a "fine whiskey". Learn more repackagers/formulators.
Our Basic No Blush (tm) is a formulated non blushing epoxy by Progressive Epoxy Polymers, Inc. (homepage). that includes additions for reduced brittleness and exclusive (only we have it) bubble breakers for a more perfect looking finish. Basic No Blush is the least expensive of the formulated epoxies and considered the best marine epoxy by many ex-users of the other formulated epoxies.
REPACKAGED EPOXY WARNING: Over the years I have seen and had reports of non-formulated, raw resin/cure epoxies (which are extremely hard and brittle) becoming crazed with millions of cracks (like shattered safety glass) in outdoor settings that experience big changes in temperature. Formulated epoxies all seem to be 'fixed' to allow for this expansion and contraction without cracking by making them less brittle and better able to handle internal stresses.
"I've been using the Basic No Blush epoxy on all my own stuff, and using up all the West epoxy on most customers boats. When the West is finally gone I'll only be using your epoxies. Good stuff. I'm rebuilding an old Rybovich so a big order in the future..." Patrick (comment with on-line order 9/4/07) ---- Order No Blush online
