How do you mix a West System 105?
To measure 105 Epoxy Resin®, 205 Fast Hardener® or 206 Slow Hardener® by weight, combine five parts resin with one part hardener. Small quantities can be mixed by volume at the same ratio.
Is West System epoxy good?
WEST SYSTEM 105 Epoxy is a professional quality, two-part epoxy system developed for high strength and good versatility.
How long does West System epoxy take to cure?
Working Time: 60–70 minutes. Initial cure to solid in thin film: 6–8 hours.
How deep can you pour West System epoxy?
While it is a slower curing system, it still should not be poured more than ¼” deep at a time. We have found that building up castings ¼” at a time allows the epoxy to cure without overheating.
Is WEST SYSTEM Epoxy self leveling?
It will flow out and self-level without “fisheyeing.” By combining it with blush-free 207 Special Clear Hardener, you can create a natural finish. You’ll just need to add a couple of coats of varnish for UV protection.
What is the mixing ratio for WEST SYSTEM Epoxy?
Depending on the hardener you select, WEST SYSTEM Epoxy is mixed at a ratio of five parts resin to one part hardener, or three parts resin to one part hardener. At the proper mix ratio, the number of chemically reactive sites in the resin balances the number of reactive sites in the hardener.
What happens if you pour resin too deep?
If your epoxy pour is too thick, the reaction can create too much heat, resulting in a product that does not cure properly with cracks or excessive bubbles. You can pour the next layer after the previous pour has gone through its heat cycle, which is usually around 24 hours.
Why did my epoxy crack?
Why does resin cracking happen? Cracking happens when resin gets too hot and cools off quickly.
Can I pour epoxy over epoxy?
Can I put another coat of epoxy over cured epoxy? Yes. Since the epoxy has cured a chemical bond is not possible so what is called a mechanical bond is needed. This simply means that the cured epoxy has to be lightly sanded before the next coat is applied: the first coat should have a matt, almost white, surface.
What happens if you put more hardener in resin?
Adding too much of either resin or hardener will alter the chemical reaction and the mixture will not cure properly.
Does epoxy resin scratch easily?
But Is It Scratch Resistant? One of the most important factors of flooring is knowing whether or not it is resistant to scratches. An epoxy coating will last longer than pretty much any other type of coating and epoxy coating by itself is scratch resistant due to the composition of its ingredients.
Can you pour epoxy over an uneven surface?
If you have an uneven surface to begin with, epoxy resin can be used to make it more level to great effect. Inherently, all of our resins have self-leveling properties that help them flow to coat a surface evenly. You can also use them to seal surfaces that are porous or have little holes, such as wood or stone.
Can you epoxy over concrete cracks?
Epoxy coatings cannot withstand the stresses associated with concrete cracks due to settling, dry shrinkage or other factors. Don’t let the fear of cracks keep you from enjoying the benefits of epoxy; with a little prep and repair work, you can move forward with your epoxy project.
How long do you have to wait between resin layers?
3-6 hours
Allow your resin to set up 3-6 hours between layers, depending on the weight of what you’re adding to the next layer. Example: if adding heavy metal charms to the layer, let previous layer set up for about 6 hours so the charm doesn’t push down into the layer below.
