Hello, I want to fill the lettering on a sandblasted HDU sign and then gild with gold leaf. I reverse blasted the letters (left the bkd flush and blasted out the letters)What is the recommended resin to use. I would like a smooth, puddle effect. Thanks, Rob

Rob, I know what I would use unless I got a recommendation from someone who has experience using something else. I would use Matthews 6001 Polyester Primer Surfacer. It was developed by Matthews especially for HDU. I would spray it heavy in the letters to act as a fill, covering all the texture created from blasting. I have used this product for filling large gouges in HDU. It hardens nicely even when put on thick. It smells exactly like Bondo.
When I've sprayed 6001, it levels well and dries to a velvety finish. It is also brushable, and it sands well. It dries very quickly. I suspect it is too porous to gild directly without sealing first with a finish coat.

Rob, Dave posted while I was still writing. The epoxy sounds like the better idea.

Would you like me to send you a no charge sample of the PB Resin?
Thanks Dave for the recommendation. I do agree, for this application, that PB Resin is the right product as you can pour it in to desired height and then gold leaf over it.
Thanks, Kellie

As long as we have Kellie on the line...everyone should check out the website for Coastal Enterprises. They have an excellent blog by some guy up in Canada that uses a lot of their product.
He has a funny name that no one can spell...but check it out anyway.

I don't think I'd try this technique for letters, but if you are pressed for time you can even gild directly on the epoxy without size.
I router carved an HDU sign with a quarter inch wide raised inline about one inch inside the outer border that I was going to gild. I used PB Resin as a doming layer on top of the inline to give a rounded effect. I was standing there looking at the resin, and from past experience knowing how sticky it is until it hardens thought, why not lay gold right onto the resin?
If it failed, I could just lightly sand until smooth and apply size the traditional way. I used a separator sheet from a book of gold leaf to check for tackiness. (Your finger could leave a permanent fingerprint) Once the epoxy was pretty firm but still tacky, I laid roll gold down right onto the epoxy. It went on easy, stuck tight and the gold was brilliant. I burnished the gold lightly with a soft brush then cleaned off the few skewings once the epoxy had set solid overnight.
It's a method I'd use again, but only if you can get the gold down fairly quickly. I don't know what the actual open time would be, and you'd have to lay the epoxy down first thing in the morning to have any chance of laying the gold the same day. My experiment was on a 4x8 so I was able to get the gold down in less than half an hour.

Dave - I had thought about that but never tried it. Glad it worked for you. When Kellie sends me my five gallon sample, I'll have to try it out.

Yes Joel, I'll be happy to send you a sample. Are you able to get FedEx at the address you have on your post?
Dave, I know you've used that technique before and it's a good one. Just tricky to know correct time to gild, especially different times of year. (temp) - Thanks for explaining it in better detail.
Raymond - the 5 Gal sample has been shipped with the truckload of free Precision Board. You haven't received it yet? ;-)
