The letters (A - D) next to the resin/hardener (ex 105A, 205A, 209C) are for matching quantity sizes. A is for a quart "set", B (gal) gallon , C is 5 gal, D is 55 gal. 205 & 206 are 5:1 resin to hardener mix, 207 & 209 hardener are 3:1.

That is, a 105A (qt) resin matches a 205A, 206A, 207SA or 209A hardener; A 105B matches a 205B, 206B, 207B or 209B hardener, etc.

The resin & hardener needs to be mixed in the correct ratio.We sell pump sets that correctly measure the ratios automatically for you. We sell kits below with everything you need or you can buy items individually.

Note 207SA, 207SB are often referred to as 207A, 207B etc.

Colored Pigment Options
Epoxy can be easily colored by using up to approx a 5% mixture of powdered line chalk (available at any hardware store - used to snap lines on a wall). These are available in any base color and can be mixed to create any color). Note that grout can also be used if earth tones are desired. Epoxy pigments also work well, but are much more expensive.

When to Choose the 207 (all weather) Hardener:  We use and sell West System's 207 product ourselves, because it is the best epoxy available anywhere.   Tests have shown that this product looks virtually brand new after a full year of harsh New England weather exposure. Note that the 207 is the clearest of all West System's epoxies.

So when (and why) should you pay more for the 207 vs. the 205 or 206 hardener, or other Brand's cheaper epoxies?  If your product will be exposed to water, humidity, large temperature variations, or direct sunlight, it is well worth the few extra dollars you spend up-front for the 207, vs. watching your product yellow or flake-off prematurely (sometimes within 1 year).  If your application will be indoors and not directly exposed to sunlight, water, and humidity, you may want to consider using the less expensive 205 or 206 hardener.

We buy, use ourselves (for our composites shop), and sell West System brand Epoxy only because it is the best.  If there was an equivalent and cheaper product on the market, we wouldn't be using West Systems.

Epoxy Fillers


403 Microfibers are made of fine cotton fibers and is used as a thickening additive with resin/hardener to create a multi-purpose adhesive. Microfibers and epoxy are particularly effective in bonding wood. Epoxy thickened with microfibers provides good gap-filling qualities while retaining excellent wetting and penetration capabilities. Microfibers are used primarily in bonding and gap-filling applications. Microfibers are non-toxic, but care should be taken to avoid inhalation. Color: Off-White.

6oz. $6.99

20oz. $16.99

20lbs. $149.99


404 High-Density filler is a thickening additive developed for maximum physical properties in hardware bonding where high-cyclic loads are anticipated. It can also be used for filleting and gap-filling where maximum strength is necessary. May be added to the resin/hardener at a rate of 20 to 30% by weight, depending on the viscosity needed. Color: Off-White.

15.2oz. $9.99

43oz. $22.99

30lbs. $165.99


405 Filleting Blend is a strong, wood-toned filler for use in glue joints and fillets on naturally-finished wooden interiors. Mixes easily with epoxy and lets you create fillets that are smooth and require little sanding. Color is a consistent tan so it can be used to modify the shade of other West System fillers.

8oz. $9.99


406 Colloidal Silica is a thickening additive used to control the viscosity of epoxy and prevent epoxy runoff in vertical and overhead joints. 406 is a very strong filler that creates a smooth mixture, ideal for general bonding and filleting. It is also our most versatile filler. Often used in combination with other fillers, it can be used to improve the improve strength, abrasion resistance, and consistency of fairing compounds, resulting in a tougher, smoother surface. Color: off-white.

1.7oz. $5.99

5.5oz. $16.99

10 lbs. $174.99


407 Low-Density filler is a blended Microballoon-based filler used primarily to make inexpensive filling and fairing putties which are easy to sand or carve while still being a reasonably good engineering material on a strength-to-weight basis. It can also be used as a thickening additive for bonding veneers and in low-stress structural applications where light weight can be beneficial. Good feathering and won't sag. Color: Reddish-Brown.

4oz. $10.99

12oz. $28.75

14 lbs. $272.00


410 The ideal low-density filler for creating a light, easily worked fairing compound especially suited for fairing large areas. 410 MICROLIGHT handles well and mixes with greater ease than 407 or Microballoons, and is approximately 30% easier to sand. It is also more economical for large fairing jobs but is not recommended under dark paint or other surfaces subjected to high temperatures. Cures to a light tan color. Do not mix 410 MICROLIGHT filler with polyester or vinylester resins. Microlight will inhibit the cure of polyester or vinylester resins.
