Drama's Materials | Liquid Latex.
hello there photo quick dramas materials video having some of these videos for a
while but so recently a lot of people have been asking about which brand of
latex are use now I don't have a particular preference for what brand of
latex I do use I do use Polly Kraft latex and the reason being is I know the
product and I know the material what I know it's gonna be reliable when I buy
it I have bought other brands in the past which the late sexist or turned out
funny color but that's been a very rare occurrence so well I don't think this
I'm really Bulls any bad latex by that brands but I just stuck with the poly
Kraft brand because just because it's reliable I know and I know why I'm gonna
get so I tend to buy the lane sex depend how much mold I've gotta do this is a
five liter container which is quite old you see it's turned orange thus for a
bit too old because they a little bit left in the bottom anyway I've got a
liter container there which is relatively new so I should continue
using this one on the next moulds that I do or this particular batch but also you
know you get there once you paint it on your layers you'll get a latex mold
which resembles something like this the material a nice durable rubber there are
a few latex mold making videos on the channel we just want to make this video
because there has been a lot of people asking about what I use and of course
you pour into you pot or container and use a brush just to brush up on the
layers brush up the layers you can see that on other videos on the channel of
course this video is just showing you what latex on I use so the price I pay
run about sometimes 50 in brush pounds for elites
Sally's container and five liters are paid 25 pounds in British pounds so the
1 liter 750 would probably be around 12 13 dollars perhaps in American dollars
the 25 pound probably be around 30 $40 I'm just guessing here in US dollars a
latex dipping rubber for self releasing flexible molds for detailed castings in
polyester resin plaster and other cold cure materials easy to use just Dipple
brush the original model in the liquid rubber then leave to dry apply the next
coat as soon as the first coat is dry so I'm using latex like 10 D I tend to make
latex molds when I'm casting concrete but notice says here you can use
polyester polyester resin but you need to prepare your mold if you're casting
polyester resin that's a topic for another day so I use latex mainly for
concrete and plaster shake well before use brush dip a thin
coat of latex on the model be careful not to puddle the latex a gentle stream
of air can help to blow latex into the finest detail and break any bubbles let
each coat dry for 4 to 16 hours in a warm ventilated room drying time depends
on temperature and humidity warm dry air is necessary for fast drying when dry
the latex loses its milky appearance and becomes slightly translucent and amber
in color so yeah you will find when you're putting your layers of latex on
you'll see especially over the first couple of coats you want to get rid of
all those air bubbles that will most likely appear on those coats and you can
only tend to blow them out or keep a fire going just to pop those bubbles to
give you a nice layer which fills in the detail and say there's plenty of videos
on the channel and whatever you chew of course show you how to do the mold
making or the mold making process so properties apply six to thirty coats
depending on the desired mold thickness molds are typically 1.5 to three
millimeters thick for large flat models apply latex in a checkerboard pattern
alternating squares between coats since there are some shrinkage on drying the
patchwork method reduces stress and warping of the latex as it dries but
I've not used that checkerboard pattern method so that's food for thought in the
future depending on the size of mold depend depend on the size of the model
which in molding will sort of dictate how many coats to put on your model to
make your mold this particular mold here which is a small bit of mold I think
that is actually 30 coats but that's a bit overkill them but sometimes to make
the smaller ones thicker to see if I get away without making a mother mold so I
could probably have in my layers up on this particular mold if I use or make a
mother mold and there's lots of mother mom making videos on the channel also so
I don't need to go into too much depth here I would put 30 layers on a
relatively big or large mold there's a dragon I've just finished and that's
probably about maybe a foot half two feet tall that had a good 30 layers of
latex on the mold so there are liquid latex I have that helps out with other
people have been asking about what round of later
I use and like I say I have no preferences just I know this product and
I use it because this reliable to me so anyway just a quick dramas materials a
video to fill in about a liquid latex so if that's watching and see you soon
you
