Review: So far the product works well and dries firm - I've used the product once so far on recently installed 3/4" oak dark stained flooring which has some poor areas from the factory, other poor areas such as knots, holes, and other imperfections were already factory repaired. I believe the boards I am working on should have been discarded. I first drilled/ground out the bad areas with a Dremel tool creating a sort of pit or valley then mixed up a small quantity of the resin and hardener using a visual calibration of 5 parts resin to 1 part hardener, I added a small amount of TransTint dye to darken the epoxy to match the factory board repairs, the total volume I prepared was around a tablespoon. The mix is quite thin so it will seep deep into cracks which was some of what I wanted but I found once the epoxy begins to setup it can still be easily worked with making it nice to fill other areas requiring careful manipulation of placement such as filling long ground out irregular cracks and chips in the wood. While the epoxy is drying bubbles will come to the surface, a heat gun worked nicely to pop the bubbles. Once dried the epoxy can be sanded or ground down as necessary, then I used a closely matching wood stain and slightly dyed it to match the surrounding area, it looks good and hopefully I can use this to repair other imperfections of the flooring so I won't need to replace any of the boards. The epoxy system includes a set of pumps but instead I planned on using a small kitchen scale to measure the resin and hardener weight/weight into small paper cups but realized the volume I required to measure in grams would be way more than I needed, the epoxy can be measured by pumps, weight, or volume. I found the name of this epoxy system on a youtube video which also shows it being used and tips on its use. I looked locally for these products but not to be found so I was pleased to see desertcart carries both the epoxy and dye. I think without dye the epoxy would harden to be clear.
Review: Good enough for Gibson Guitars! Good enough for me. - I’ve been using West Systems in high end custom guitar building since the early 90’s. Simply stated the best epoxy glue I have ever use and refer it to many. Good enough to build boats I would say awesome building guitars too. Excellent for headstock break repairs as well as I learned about this glue while employed at The Gibson Custom Shop. Good enough for Gibson good enough for me. Fast hardener for winter, slow for summer.

## Features

- CONVENIENT EPOXY BUNDLE contains one can of WEST SYSTEM 105-A Resin (32 fl oz), WEST SYSTEM 205-A Fast Hardener (7 fl oz), and one set of calibrated 300 Mini Pumps. 205 Fast Hardener is a medium-viscosity epoxy curing agent. It is useful in a majority of bonding situations, and at lower temperatures. 205 Fast Hardener produces a rapid epoxy cure that develops physical properties quickly at room temperature.
- 105 EPOXY RESIN is a clear, pale yellow, low-viscosity liquid epoxy resin. Blended with 205 Fast Hardener at a 5:1 ratio, it cures to a hard, solid plastic with superior physical properties. It will wet out and bond with wood fiber, fiberglass, reinforcing fabrics and a variety of metals. (205 Fast Hardener is not intended for clear coating.)
- POT LIFE AT 72°F (22°C) is 9 to 12 minutes. Cures to a solid state in 6 to 8 hours. Cures to maximum strength in 1 to 4 days. Minimum recommended working temperature is 40°F (4°C). Does not contain VOCs and has relatively high flash point and no solvent odor, making it much friendlier to use than styrenated resins.
- EXCELLENT FOR COATNG OR BONDING, this epoxy is easily modified with WEST SYSTEM fillers, pigments, and additives to suit an enormous variety of construction and repair projects, including fiberglass boat repair, strip kayak and canoe construction. Resin viscosity is approximately 1000 centipoise at 72°F (22°C)
- INCLUDES CALIBRATED PUMPS that dispense 105 Resin & 205 Fast Hardener at the correct 5-part resin to 1-part hardener mix ratio. One pump stroke of resin for each one pump stroke of hardener yields 0.8 fl oz of the exact 5:1 epoxy mix ratio. These durable polypropylene pumps provide years of dependable service.

## Questions & Answers

**Q: What's the shelf life once the canister's have been opened?**
A: I have been using West Epoxy for years and have never had a batch go bad.  The shelf life on an individual unit is unknown to me, but I have gone at least three years on a single quart.  The hardener changes color from clear to brownish over time, however, it seems to remain viable.  When the product is cold it becomes too viscous for the pumps in which case I place the container in warm water for a few minutes to restore the proper .liquidity, being mindful that if you warm it up too much it will speed up the cure time.

**Q: Is there are weight to weight ratio between 105 Resin and 205 Hardener so do not have to measure by volume?**
A: FIVE-PART RESIN TO ONE-PART HARDENER RATIO: Mix 205 Fast Epoxy Hardener with 105 Epoxy Resin in a five-part resin to one-part hardener ratio weight or volume

**Q: Can this be used to repair decks?**
A: Yes, I have used this product to repair rot on decks.  I would scoop out the rot, let it dry completely and coat the area with full strength epoxy.  As a second step if the area is large I would use a powdered additive and make a putty like filler.  work clean as cured epoxy if tough to remove.....even sanding can be tough.  Remember, cured epoxy degrades in sunlight so it should be painted or stained with a solid stain.

**Q: How well does this stuff work on delamintion on the front of a travel trailer between the fiber glass and plywood behind the fiberglass?**
A: I have a sailboat that has fiberglass with a plywood core and I think it would work well if you can find a way to inject the 105 In adequate amounts so that it spreads out and then to compress the fiberglass against the plywood until it cures.  If you drill holes in the fiberglass to inject the epoxy, I would use small pieces of fiberglass cloth saturated with epoxy to cover the holes when you are through.  Then you can sand and paint without a dimple where you drilled the holes.   If you can pull off the trim and pull the fiberglass away from the plywood, then you may want to consider tacking a layer of fiberglass cloth to the plywood that you can saturate before you put it back together. I don’t know the temperature where you are, so I would look at a West System chart to find out whether to use fast cure or slow cure depending on the temperature.  Good Luck delamination issues can be trying.

### ⭐⭐⭐⭐⭐ Great epoxy for repairing an RV Filon wall
*by A***R on May 25, 2023*

This epoxy worked well to repair a delamination on mu Travel trailer wall. The job was somewhat challenging but very doable for someone with mechanical abilities. My delamination was about 2'8" wide by 6' high. I did remove the water heater to gain the best access and worked in no more than 2'x2' sections. The wall is now solid and saved myself a lot of money. I used about 1/2 to 2/3 of the gallon of epoxy for my repair.
