![]() The ratio really depends on what you want to achieve - what works best for your application. here: "I tried dilute Milliput and although it worked (sort of) it was messy and time consuming"). Note however, that some users complain about the manipulation of this mix (e.g. ![]() Here someone suggest adding a little soap with the water, as this will not only let it mix better, but also increase the drying time, although I think this might be detrimental for the structure. If what you need is a spreadable paste, start with an epoxy paste. If what you need is liquid epoxy, just start with that rather than adulterating epoxy putty. Epoxy-based products work best when used as manufactured start with a product of the right consistency for your needs. If your objective is just a surface coating or filler for minor defects, which doesn't need to be durable and won't be subject to a lot of handling, thinned Milliput may be adequate. The more water you add, the more it will degrade the result. Also, the moisture in the putty in contact with the surface it's applied to weakens the bond holding it in place. Smoothing the surface doesn't have a significant effect on the rest of the material.īut if you mix water into the putty, some of it will be trapped when the epoxy cures, which degrades and weakens the cured material. Water can be exploited to smooth the surface because it thins the filler and the epoxy doesn't stick when it or the surface is wet. The epoxy component doesn't mix with water, it's the filler that's affected. Some putties, like Milliput, will be softened by water while still uncured, but that's more of a side effect of the composition than a feature. The filler thickens it to give it the desired handling characteristics. The epoxy does the work of holding the mixture together and bonding it to the substrate. Epoxy putty, including Milliput, is a mixture of liquid epoxy and filler that makes the composite the consistency of clay.
