What is the mix ratio of clear coat?
1:1 mix ratio by volume of part A and part B.

What is the proper way to mix clear cast?
Clear cast must be mixed using equal volumes of both A and B sides. Using graduated mixing containers helps to ensure that you accurately mix equal amounts. When mixing multiple batches, it helps to have a dedicated side A and side B measuring cup, which are then added to a larger mixing container. Once measured, Amazing Clear Cast must be mixed extremely well. You must continually scrape the sides and bottom of the mixing container, also scrape off the mixing stick on the lip of the mixing container to ensure all resin is thoroughly mixed. Mixing should take a minimum of 4-5 minutes. Half gallon to gallon batches will take longer to mix. Under-mixing can cause tackiness on the surface or not cure properly.
Why is my bar coating not curing and/or tacky?
There are a few possible causes for this.
- You did not mix the resin thoroughly enough. This usually results in areas on the bar top that are tacky, while others are not.
- You went off-ratio. Failure to mix 1 to 1 by volume ratio can cause the entire surface to be tacky or in some extreme instances cause the resin not to cure at all.
- Cool room temperatures. Ideal coating temperatures are 75-80F. If the room temperature is below 70F, the resin will cure slowly and may require that the room temperature be increased to facilitate curing. Heat guns will not work, as you need long temp heat. Some remedies for random tackiness is to apply another coat, mixed well. If the surface is soft and gummy after 4 days, you may have to scrape it off, as re-coating will not help.
Can I use Amazing Clear Cast for outdoor applications?
We generally do not recommend ACC for outdoor applications, as the UV exposure will cause the resin to develop a yellow hue rather quickly . There are some instances where it may be reasonable such as adding Alumilite dye or Alumidust to color the resin, which often times negates or minimizes the yellowing. Also applying it over certain toned wood surfaces that have more yellow and orange hues to it would make the yellowing less noticeable.
What can I use to change the color or look of Amazing Clear Cast?
ACC will accept water-free dyes such as Alumilite liquid Dye. Based on the dye chosen, it can give you a translucent color or an opaque color. Alumilite Alumidust powders can give you dynamic colors that give you a vibrant pearlized color. Alumilite Metallic powders can also be added to ACC to produce copper, bronze, or gold effects.
Will Amazing Clear Cast yellow?
Yes, as will all epoxy chemistry, ACC will yellow over time. While there are UV inhibitors in our system that help it resist longer than some competitor products, a yellow hue will develop over time. Many times this is not ever noticed based on the underlying surface color and because of the thin layer. Applications where ACC is applied over bright white surfaces or when pouring thicker layers, yellowing may be more evident.
What is the shelf-life of Amazing Clear Cast?
ACC has a shelf life of 1 year. Once ACC is opened, this time can be shorter based on moisture contamination from humidity. Amazing Clear Cast B side will naturally yellow over time and with exposure to air. While this can cause a slight yellow hue to cured coatings, it does not have an affect on the ultimate cure of the product.
How do I clean the surface once cured?
After the coating is fully cured, you can use a soft cloth with soapy water. To remove streaks and keep it glossy, you can use mild cleaners such as glass cleaner.
Why do I get a ring that forms under my glass in the coating?
This is not an uncommon occurrence. Amazing Clear Cast has been formulated to provide a high gloss durable surface. While it may feel hard, it has a flexible backbone to absorb impacts from mugs or plates that may be dropped onto the surface, making it less likely to crack or shatter. In instances where the coating is new, it may be still curing/hardening. You should find that the rings will slowly disappear or heal within hours.
Is Amazing Clear Cast safe to use?
Amazing Clear Cast is a 100% solids and VOC-free epoxy. While it is a very safe product to use, it is important to read all directions, cautions, and SDS prior to use. As with all chemical products, proper safety precautions should be followed. Some individuals may be more sensitive to chemicals than others, causing them to take extra precautions to limit exposure.
What's the best way to pop air bubbles?
Amazing Clear Cast cures slowly to allow air bubbles to rise to the surface and pop. To help pop them at or near the surface, you can spray a mist of isopropyl alcohol (93%) over the surface during the first hour after application. You can purchase a fine mist spray bottle under Tools & Equipment. Another option is waving a a propane torch over the surface. The flame should never come in contact with the resin, only the heat from the torch. Do not use alcohol in conjunction with a propane torch or the presence of any flame or ignition source!
How thick can I pour Amazing Clear Cast?
We recommend not pouring any thicker than 3/8-1/2 inch per pour. Pouring ACC thicker causes the resin to cure too quickly causing excess heat to build, rippling on the surface, and air bubble entrapment. Subsequent layers can be done as soon and 4-6 hours, but no longer than 12 hrs for adequate adhesion. Going beyond 12 hrs will require light abrasion and cleaning of the surface with alcohol prior to reapplication.
Is it necessary to seal the surface prior to coating?
No, it is not necessary in all situations. If you are pouring over a surface that is not porous, sealing is not generally needed. With substrates such as wood, paper, foam, or even some rock will require a skim coat of ACC to seal up the surface. Other sealers can be used as long as they dry clear and are tested for adhesion and comparability with ACC. Sealing the surface helps to minimize air bubbles from continually leaching from the pores as the resin penetrates. Paper-based items may need to be coated with a water-based white glue based sealer to prevent color change or saturation.
