Liquid Sprue ?
Posted by Wirraway on Tuesday, March 31, 2015 9:07 PM
I want to try and make my first batch of liquid sprue. I want to see if it has advantages or not over using Tamiya Putty, which is what I have been using for years. I know you have to chop the sprue up into fairly small bits so that it will dissolve, just wondering what the ration of sprue to cement would be ? I normally buy the Revell Contacta Professional liquid glue in the blue bottle, it seems to be the most prevalent in hobby shops around my neck of the woods.

I used to do that. There's no particular ratio that I used; I just got to a consistency that I liked. Do shave it up real fine while adding it to the glue so it dissolves better.

try a pencil sharpener to ahem 'shave' the sprues, much quicker

Funny You Should Ask :

     I take the sprue ( Chops ) and use about a quarter of them per bottle . I have some old sprues that I sand down for the dust .This gets poured in too .

  You should mix to the thickness you need .This will take awhile , then check ,If it's too thin add more plastic ! It is definitely great for a two part hull ( put on the inside ) .or that pesky ,  ill fitting aircraft fuselage !

Yeah, some people call this stuff "SPRUE-GOO". I just started using it a few months ago, and I'm barely using any filler putty anymore. I love this stuff!

I know some folks who just dissolve the sprue in lacquer thinner rather than liquid cement, but I have not tried it myself. They adjust thickness by adding solvent or sprue as needed.

Several different solvenys you can use. Just make sure the storage jar is air tight or you will have a jar of sticky goo.

Curious...why?

I swear by Bondo.

I've used liquid sprue when I had a wide or deep area to fill or a load bearing area. The liquid sprue will be stronger than a putty like Bondo.

I'd never consider that. Makes sense, thanks.
