I am trying to do this with Silicon and Rosco Gray, as I came across messages on the forum indicating this would work. Have been trying for 3 months now with various amounts but with no luck. Here is what I have done, if anyone can point out any flaws that would be great. I should mention I have an FTIR setup and if I use Dycem I great fantastic blobs but it does not unstick so the blobs never go away, but it shows at least the FTIR effect can work. Am in UK so cannot get Xylol.
1) Silicon and tracing paper
Wrinkled, blobs were not great, screen was washed out.
2) Silicon and Rosco Gray
Tried Multipurpose clear silicon sealant (http://www.diy.com/nav/decor/tiles/adhesives-sealants/sealants/-specificproducttype-general_purpose_sealant/-material>silicone/Soudal-Trade-Multi-Purpose-Silicone-Sealant-Clear-300ml-11348649) but this was too thick.
Settled on a Soudal Trade Glazing Silicone Sealant Clear 300ml which is much more spreadable and dissolves in the acetone.
All tests are using nail polish remover from Tesco for the acetone, appears to dissolve sealant eventually. Makes more of a spreadable paste than a combined mixture. Could this be an issue??
Mixture in 1 to 1 proportions, also tried 2 sealant to 1 acetone, and 1 sealant to 2 acetone (teaspoon for a rough 10x8 inch tester of Rosco Gray) Mixture does not really end up like in Tinkermans video where its more gloopy but can be poored on or spread on with a knife.
Am using gloss rollers (http://www.diy.com/nav/decor/decorating-supplies/rollers-pads/mini_roller_sleeves/-specificproducttype-gloss_roller_sleeves/B-and-Q-Mini-Roller-Gloss-Sleeve-Refills-Pack-of-10-10548959?skuId=11039491). Not sure if these are that great for producing the micro-bumps required but its the only ones I can find where I live, could this be the problem??
Tried with 1 layer, 3 layers ( sometimes an effect when semi wet still ), 6 layers. Sometimes there is an effect while wet but once dry, not a hint of a blob.
3) Ordered some translucent silicon sheet from polymax, this failed completely to produce any blobs whatsoever. Not sure what I can use this for now…
I am stumped as to what to do next, any suggestions?
