When the copy is hard we can go “peeling” the layer of plaster and alginate.Īs you can see in the photos, in the eyebrows has appeared excess material, that’s because there we didn’t applied well the alginate, the plaster is very easy to sand so we can fix those flaws with sandpaper.įor the project we undertook wich I’m not going to tell until we finish (currently parked) we also needed both hands. In our case, we filled the mold with plaster (you can buy at any hardware store or warehouse building) and let dry. The only thing we have to remember is to plug the nostrils, so that the material does not slip. Make molds and reproductions is an art, but in this case as we have reproduced only the face, and also the mold is for a single copy, there is no complication. In the picture there is an optical effect by which it seems that we are seeing the positive, but this is the mold (negative) Once in our hands we can observe every detail printed in the mold. Better if the model can cooperate to make sure you do not harm him. Once the plaster dries, very carefully we began to unmold. Miguel, who was the model in this case, threw her head back to help us in the placement of bands and then was uncomfortable. We try to cover the entire surface, preferably in different directions to make it stronger, and extend the plaster with the hand.Īt this point a warning: Bands take longer to dry and when they do, theycompletely prevent movement, so you have to ensure that the model is in a comfortable position. To set in the strips we just have to cut them in a manageable size and put them in water to go sticking. This is achieved using plaster bandages (we can buy at any pharmacy) The mask is not strong enough by itself, so we need something that makes a box or container.
We must be attentive at all times the welfare of our model. Let it dry a few minutes until it has completely changed color in the case of chromatic alginate (when you mix is ?pink and turns white when dries) or until you touch and not leave any trace (although still flexible). Once it starts hardening we can let accidentally uncovered areas and remain unfilled spaces (in the following photos will see what happens in these areas). Mix the powder with cold water (the colder more time we have to work) in the proportions indicated by the manufacturer.Ĭover the entire surface uniformly while the alginate paste is still fairly fluid. If done in several batches, the alginate will not stick well on himself and wrinkles and imperfections appear. If the work surface is large (as in this case) would help some extra hands, because we should cover everything at once. There are different types, with more or less working time and some of them change color when they dry (chromatic alginate). We didn’t, just took care not to obstruct the air intake, but I insist that it is advisable. So he can breathe well we can put a couple of tubes in the nostrils. With a clean face, we must collect hair and cover eyebrows and lashes with vaseline to keep from sticking to the mold.
Nor will be able to talk, so you should agree in some sign just in case he feels the need we remove the mask. It is possible that for some people this represents a problem. The mold making is simple, but I recommend to have the material for pouring (which is going to make the copy) ready, because the alginate will crumble when just dry.Īlginate is not dangerous, but in the case of face molds must take into account that the model is going to be a while with his face completely covered and will not be able to move. By chance we met a prosthetic that gave us a bit, and eventually over time we found our supplier that also sells online, so here it is:įor those of you who live out of here I recommend:
Looking for information on the alginate, I read everywhere: “you can find in any dental material store”, but it looks that we were the only ones who do not have dental deposits around the corner … (Really, we asked in several places and it was not that simple, at least here in Sevilla). It is a powder that mixed with water becomes a paste in minutes and will allow us to make a single copy,( it bcomes breakable when dryes) To do this we are going to use is “dental alginate” used to make dentures negative.
#MAKE A FACE MOLD PROFESSIONAL#
Without actually using professional methods and materials such as latex or silicone, we can make a pretty faithful reproduction of a face (we could have done the whole head, but what interested us at this time was a part of the face and hands). Many of us have ever done at school or at home a mask using plaster bandages.
