Hey Matthieu, appreciate the tutorial. I have a mold which I have been using for over a year now and have molded hundreds of products from it. It is not in a good condition and I wanted to ask that can I repair it by sanding it down and then spraying tooling gelcoat on it, then again sanding it for making it smooth and followed by buffing. Also any idea by doing so, how many more products will I be able to mold from it. The mold is quite large, around 1.5m x 0.5m in length and making a new mold will be time consuming and not economically feasible for me right now.
Hey, great video! Do you recommend doing this for the entire tool surface of a mold? I had an incident where the entire surface degraded. I was wondering if I can sand, roughen and reapply the gel coat and polish it to a gloss finish without fearing the gel coat ripping off during a product pull.
Depends on what it was used, in future videos you'll see me reuse brushes when applying a pattern coat on the part, I keep them in acetone then while waiting for layers to cure
On small amounts you can get away with higher amounts yes, so 4% here, but do some testing first as not all Mekp hardeners have same purity so might differ a bit, as well as ambiant temperatures, I'm mostly working around 20°c

3 weeks, what did you do? might be easier to just make another mold and learn from the lessons
What polish did you use to give it a glossy finish???
Do you know if you could use body filler or glaze for pin holes in mold
I still try to find Silicon use to siloconebagging. Do you know where i can buy? Great video
I think smooth on is selling that, they have a vieeo online... Haven't tried it tho
What’s the brand of used polisher?
hi i got a motorcycle that uses a pair of side pannels and the mould is chipped on edge how is best way to restore ?
Like in this video :)
thanks
Do you re-use brushes?

mooi gedaan Matthieu
Thanks 👍
Did I hear this right? 4% MEKP? I always thought 2% was the upper limit.
Another excellent video, by the way :)
