Watering Down Paste and Glue

0

I know you have a guide for paste vs glue, but do you have a similar one for when to water things down and when to leave it thick? I ask because I hear you mention in your videos a lot that to water the paste/glue down to “the right consistency,” but not always saying what that means for each job. When should we make sure that our glue/paste is thick and when do we need it thin?

 

P.S. Sorry I’ve been spamming up the forums. My work is only willing to pay for a 1-month membership and I’m trying to take full advantage while I can.

Hi Sarah, Please don't worry about how many questions you ask. They all will help other students!

When I say the right consistency for paste or glue it is situation specific but here are some generalities.

Glue should be fluid so that it will spread easily like paint. However, if the material you are working with is a dry leather you will want the glue to be as dry as possible so you would avoid adding water or paste to thin it down. 

Paste should hold together rather than flow or drip. If you add too much water it will lose it's tack. It should stay on the brush when you pick up a glop of it and turn the brush over. It is too thick and needs more water when it is too hard to spread. 

It is a fine balance. I will always start by adding about a teaspoon to an eighth cup but I never think of it in these terms. I just add a bit of water to the 1 inch of paste in the bottom of a small cup and stir it up to see what it feels like.

I hope that all makes sense! 

Cheers.
