Joining plastic parts by way of cement seems like a great idea, so let’s talk more about it in the adhesion department. We have seen putty type cement where the substances are either comes from a tube as a paste material, or two separate substance (hardener and adhesive) joined together to actually work. But now let’s look at the liquid forms that is used with a brush applicator; I have Mr Hobby Mr Cement S type and Deluxe type. These are great for joining plastic together, the right words to describe it is “plastic melding” wherein instead of acting as a third party adhesive material (ala Super Glue) these liquid cement actually melts the plastic surfaces in just enough time to really join the two plastic parts together as the meld dries up or “cured”.

The Two Types of Mr Cement

Mr Hobby Mr Cement S, is the thinner of the two, in that the substance is more closer to water when it comes viscosity, and because of that it can be absorbed by the plastic surface and evaporate very quickly. During the curing time the parts should have been placed and held tight against each other already as the sediment is brush applied to the contact crevice line and begins the melding process. Mr Cement S is ideal for cleaner patching of smaller detail plastic parts because it usually leaves very little trace of adhesion. Be aware though that this liquid being thin does not stick to surfaces quite as fast if the joined parts are not really held tight together, so this thin cement really requires patience to get great results.

Mr Hobby Mr Cement Deluxe, is the standard type, it cures and evaporates slower than S type but the meld process is more guaranteed given enough time is spared to let itself glues the parts together. I recommend that the Deluxe type should be used as the base setter in joining plastic parts, then use the S type for extra support, especially on crevices that the water sediment from S type can reach to easily. I also recommend necessary support tools like clamps and clippers to hold parts joined together as they cure.

I really think that one should buy both of these products, as they are also complementary to each other; use the Deluxe type is for the initial setting of plastic parts and use the S type for extra added melding support.
