Great to watch a master at work. I'm still unclear as to what materials you are using to fasten the silk and then seal it before painting. You mentioned a material that was catalyzed 2:1. 1. What is this material? 2. Are you using it to fasten the silk to the balsa and also using the same material on top of the silk with talc added to fill the silk and achieve a smooth surface?3. What is the mix ratio for the talc? Thanks, Ted.
The paint used in the process of applying silk is a 2: 1 urethane paint. The mixing ratio of thinner and talc is changed for each process. The details of the method are likely to be the copyright of the flight hobby. I always think that it is better to use thinners that are slow-drying.
The first formulation is sanding sealer 4: hardener 2: talc 8: thinner 8. After applying and drying, almost everything is scraped off. This makes the surface quite smooth.
Is the sanding sealer clear or does it have some colour. From the pics I’ve seen it appears to be milky white in the container but clear when applied to the silk.
Thank you for that. So the sanding sealer without talc is milky white. The mixing ratio of 2:1 is similar to a clear coat but I am guessing the paint is probably a primer.
Here in USA, the closest product I can find to meet this description is a catalyzed clear sealer from Lenmar....MegaVar® Water White Catalyzed Vinyl Sealer 1C.5300 Seems to only be available in gallons. Probably expensive as well but I won't know till next week as it is available locally in central Florida.

My sanding sealer is originally milky white. When mixed with talc, it turns white. When applying silk, talc is not mixed so it becomes transparent.
