Hey Gang:

Anyone know the recommendation ratio of paste/hardener for Morini Grip Paste?

The instructions say to mix "in proportion" and suggest that more hardener = faster cure time . . . but don't say exactly what "proportion" is considered baseline.

I am assuming it isn't 1:1 because they shipped a little tube of hardener for a big can of paste. Also, my Hammerli grip paste (IIRC) was somewhere about 6:1? 9:1? or thereabouts.

About 9:1 ratio. The volume of the pots provides a clue.

If you want an application to set faster, add more hardner.

The Hammerli paste is the same BTW just buy the lower cost and what is available!

Thanks Paul- I assumed they were at least similar in composition- and you are quite right; by volume, they gave me about 9 times as much paste as hardener!

Steve,

I have the Hammerli grip paste, and according to Larry's, the ratio is 25:1. This works for me. It takes 2 or 3 minutes for it to set with this ratio, but at least you don't get burned by an overly hot mixture.

Slightly off topic - but still on Grip Paste.

I've recently purchased a Morini 84e and am thinking it will soon be time to make some grip alterations. Up until now, on my other pistols grips I've only ever used wood dough type fillers that harden on exposure to the air. Does using Morini grip paste have any advantages over using the standard plastic wood type fillers purchased from a hardware store?

I tend to use it at about 20:1 - gives you a little bit more working time when it's at the soft putty stage especially in hot temperatures. I recon I get about 3 or 4 minutes before it sets too hard (after it has started to set). Mind you I have a very small pot of hardener so that also ensures I don't run out of hardener first ;)

Typical hardwaer store wood fillers are often water based, and as you said, cure by evaporation. The Morini paste is an epoxy and dries by chemical reaction. As such it won't shrink upon curing, thus providing a truer fit to the hand. It's probably more durable, as well. My preference is for a product called Realwood. This is an epoxy packaged in paste form in which the resin and catalyst are two parts of the paste. Imagine a Twinky. You roll the paste into a ball, mixing the two parts, and then apply and fit to the grip as usual. It is very durable, doesn't shrink, comes in various shades to match different wood ( their oak matches walnut nicely) and can be stained and finished if that matters. Oh, it's much less expensive than the Morini paste.
