What are the mixing and pouring tips for the Rio Flow Kit?



PLEASE NOTE: We recommend to mix resin only when you know what you’re going to create, avoid letting it sit in the container.

Before mixing, pour both the RIO FLOW RESIN “A” / RIO FLOW HARDENER “B” in different containers. Remember the mixing ratio quantity will be of 3:1 (3 of Resin and 1 of hardener). 

*Room temp. ideally should be around 21C/70F

*Mix both Resin A and B into one container (use a vessel that is wide), pour resin first, then hardener and stir slowly the portions of RIO FLOW RESIN A and RIO FLOW HARDENER B using a spatula for a couple of minutes.

*Mix for 5-7 min MAX 

*Do not use power mixers

*Stir gently as if it was tea, not pancakes batter

*When adding colors or pigments, stir them using a spatula until you have a constant uniform color.

*Add pigments at the end of mixing and don’t over mix, pigments in general speed up the curing process.For Rio Flow Kit we recommend pouring a maximum of 1.5 Inches per application until it cures. Once after curing if you wish to add another layer on top, you can do so.


Before pouring the RIO FLOW resin, we advise leaving the resin from 30 minutes to 8 Hours so all bubbles will be released as you see fit. It is recommended to place the mix in a clean container and lightly stir it to ensure that the mix is uniform, particularly from the mix that was in contact with the surface of the mixing container.

Pour the mix at a single point and avoid spreading it over the entire surface in order to allow the product to displace air as it flows. Using a heat gun can also help you to remove undesired bubbles once you’ve finished pouring.

This resin can be applied in castings with a recommended thickness of 1.5 inch., in order to ensure adequate leveling and avoid overheating that may result in pours thicker than 2.5” and causing possible wood deformation and entrapment of bubbles.


To ensure good adhesion between castings and avoid contraction, it’s recommended to perform the next pour in 24 hrs. Repeat until the required thickness is achieved. If you wish to further polish your piece, it is recommended to do so 48 hrs. after the last pour.
