softworm Posted January 27, 2012 Report Share Posted January 27, 2012 Been making some water putty molds. When flooding the molds ( I use elmers wood glue mixed with water) how long do you let the glue cure (after draining it from mold) before you do it a second time?

bassman2169 Posted January 27, 2012 Report Share Posted January 27, 2012 Just wait until it is skinned over. You can see the spots that are still wet, they are shiny. Speed the process by putting it in front of a heater or fan. Usually takes thirty minutes to an hour to dry, depending on humidity and how much water was added.

mark poulson Posted January 27, 2012 Report Share Posted January 27, 2012 I've found that using D2T, thinned with denatured alcohol after it's thoroughly mixed, holds up better than carpenter's wood glue. Two coats seem to do it for me. The first is 1/1, and really soaks in. The second is more like 80% epoxy, 20% alcohol, and it seals the surface for a smooth face.

t-billy Posted January 28, 2012 Report Share Posted January 28, 2012 (edited) I flood the mold,let soak for 15-20 minutes,drain well,then bake at 150 for a couple hours. I get a nice ceramic like finish with one coat every time. Roughly 60%water-40% glue mix. Edited January 28, 2012 by t-billy Quote Link to comment Share on other sites More sharing options...

t-billy Posted January 28, 2012 Report Share Posted January 28, 2012 I'll have to give that method a try. Make sure you use Elmers wood glue Mark. I used a different brand once and the results weren't anywhere near as good. Quote Link to comment Share on other sites More sharing options...
softworm Posted January 30, 2012 Author Report Share Posted January 30, 2012 Thanks for the replys guys. I'm gonna give both methods a try. My local hardware store was out of Elmers wood glue and I used Dap. Not getting the same results as the Elmers, seems like its taking it longer to cure. I've not been letting the cavities completely dry before I flood a second time. This might be while its taking longer, but I never let the Elmers completely dry before I flooded a second and third time. T-Billy your methood of baking the mold after flooding and draining, this donen't make the mold brittle? I baked one a little too long once and it cracked everywhere after a few pours. I usually bake mine a couple of hours or a little longer at 225 before I use the flooding methood. Just want to make sure the second baking dosent cause problems.

t-billy Posted January 30, 2012 Report Share Posted January 30, 2012 The pop will get brittle if you get the temp too high. I've read on here that the threshold is around 225. I bake my pop molds at 175 with the door slightly cracked to let moisture out for several hours. 3-4hrs with no ill effects. Then I flood the cavity and coat the entire face of the mold with the Elmers wood glue mix and let soak for 15-20 minutes. Drain well and bake at 150 for a couple hours to cure the glue. Perfect finish with one coat every time with no durability issues. The other type of glue I tried was Titebond. It didn't work well at all. The finish had a rough texture.

nova Posted January 30, 2012 Report Share Posted January 30, 2012 Make sure you use Elmers wood glue Mark. I used a different brand once and the results weren't anywhere near as good. I use the white glue from the dollar store.....works just fine. www.novalures.com Quote Link to comment Share on other sites More sharing options...
t-billy Posted January 30, 2012 Report Share Posted January 30, 2012 I use the white glue from the dollar store.....works just fine. www.novalures.com Maybe all white glues are the same. I don't know. That's definitely not the case with wood glues. I tried white glue when I first started. I always had to apply multiple coats to get a good seal. With the wood glue it's one and done. That's the case with me anyway. I can't speak for anyone else. Quote Link to comment Share on other sites More sharing options...
