DIY silicone molds for mastic, silicone molds, how to make a silicone mold. Do-it-yourself silicone molds How molds are made

Silicone sealants can be divided into three types: neutral, acidic and containing fillers. Sealants with fillers for creating silicone molds are not suitable at all. Their texture excludes the transfer of all subtleties in the event that leaves or petals are used as a sample, and there will be more polishing for an object made in such forms. It is not always possible to distinguish one sealant from another by the inscriptions on the label, and therefore you should also rely on feelings - acrylic sealants with fillers are always heavier than ordinary ones.

Of the neutral and acidic sealants, you can choose any, but acidic is preferable, since it is the easiest to part with the forms after hardening and is much cheaper. You can tell them apart by the strong smell of vinegar. If there is a choice between transparent and opaque, you should choose transparent, as it allows you to see flaws in the form of air bubbles and get rid of them before solidification.

When making molds of flowers, fruits and leaves, the material is best harvested in autumn, when all the leaves are old and have a good, crisp texture.

Mold making

The sealant is applied to a piece of plastic in such an amount that it is enough for the size of the leaf when leveling with a small margin and with a layer thickness of at least 7-10 mm. A thinner mold runs the risk of tearing quickly. In order to avoid bubbles, the sealant is poured into one point in a slide, quickly and in a thick stream. Smooth with a finger dipped in soapy water to avoid sticking of the sealant.

After pouring, the silicone die should dry for a couple of minutes, then the leaf-petal lubricated with soapy water is pressed gently into the silicone, starting from the center, with smooth movements, expelling all the air and achieving a snug fit. The sheet should be smeared evenly, but without drops of water. Oils and hand creams should not be used to lubricate the model leaves. The design dries for at least a day, if the air in the room is too dry, you can cover the composition with a glass jar on top so that the sheet does not dry out ahead of time and does not distort the print. The curing time of the sealant is written on its packaging, and it rarely exceeds 5 mm per day.

After drying, the sheet is removed, and it is better to store the finished molds in separate silicone bags each, since even completely dried silicone tends to stick together and deform.

Wonderful realistic flowers from foamiran are not obtained by everyone. In order for leaves, buds, various small elements to be approximately the same shape and have a clear texture, special forms are used. They are called molds and have a flat surface with a noticeable relief. Viners are also distinguished - this is another type of form, most often made of silicone and having volume.

If you look at the photos of beautiful molds, it becomes clear that with their help you can sculpt any detailed copy of a plant. Such blanks are not cheap, and the work will require forms with different textures. That is why many craftswomen tend to spend quite a bit of time and money to make the right molds with the right relief on their own.

Available materials for creativity

The most obvious option for making molds at home is polymer clay. It is sufficiently viscous and plastic to accept an imprint in the smallest details, it hardens well. The blanks made from it are used repeatedly without losing their properties.

As an alternative material for veiners, some needlewomen take silicone sealant. Its advantages:

• hardens quickly;
• is able to fill the slightest cracks, which means it gives a clear impression;
• available at any hardware store
• suitable for continuous use.

Sometimes the sealant is used not in its pure form, but in a mixed one. To do this, it is combined in a 1: 1 ratio with potato and corn starch. And after thorough mixing, you can start making molds with your own hands.

We make molds from sealant

The silicone mold for bulk impressions is made simply and with a minimum set of tools. We will need:

• the sealant itself
• small container
• small spatula,
• sheet to be printed
• scissors,
• transparent film (you can take it from a stationery folder),
• paper A 4 (1 sheet).

Instructions on how to make molds are simple. First, on a sheet of paper, the contour of the leaf is outlined, from which an imprint will be made. Lay a transparent film on top of the drawing.

Squeeze the silicone composition in a small amount into the prepared container. We take the silicone with a spatula and carefully apply it to the film so as to close the contour, following all its curves.

The leaflet from which the mold will be made is lubricated over the entire surface with a layer of oil and applied to the silicone mass. Now it remains to wait until the workpiece dries. This will take at least two days. The maximum drying time is 4 days, it all depends on the composition of the selected sealant.

After drying, the leaf is easily removed with a needle and removed. And you will have a wonderful mold, which should be slightly trimmed with scissors to adjust the shape. With it, you will definitely be able to create naturalistic leaves from foamiran.

Making molds from polymer clay

Working with polymer clay is a pleasure. It has the perfect consistency to absorb all the slightest veins and relief of the sheet. If the mass you have is not plastic enough, it should be well kneaded in the palms with a small amount of fat cream or petroleum jelly. Then it will acquire the desired viscosity.

It is better to take a living leaf from a plant that has a clear relief with many veins. Experts advise begonia, blackberry or raspberry.

Still need to prepare:

• an unnecessary ceramic flat plate (or a tile left after repair),
• sharp knife with a thin blade (clerical is suitable),
• rolling pin,
• baking tray,
• needle.

The manufacturing process is not complicated, and soon you yourself will be able to give a master class on how to make molds with your own hands.

First, roll out well-kneaded clay on a tile in a thick layer. Then firmly press the selected leaflet to it. It should be gently straightened, significantly pressing with your fingers, in order to transfer the pattern as much as possible. At the end, it is worth rolling over it with a rolling pin several times.

Gently pry the edge of the sheet with a needle and remove it. We cut off the excess mass with a clerical knife so that the workpiece acquires a shape close to the original. We have received a mold negative, which should now be baked as written in the instructions on the clay packaging.

Note!

When the negatives are "baked" and cooled down, we moisten them with water from the side where the veins were imprinted. We put them on the second rolled piece of clay. We repeat the operation with pressing with fingers and a rolling pin.

We remove the negatives, and cut the resulting molds with a knife and send them to the oven. That's all. After cooling, you can start sculpting.

Another way to create molds

Every housewife has potato starch in her kitchen. If you add corn to it, plus silicone sealant, then a composition will appear in order to realize another idea on how to make molds. The mixture must be combined in a small cup, first stirring with a stick. Then you should put on medical gloves and knead the composition to the end by hand.

We separate one part from the resulting mass and sculpt 2 balls of a larger and smaller size from it.

We roll out the first blank so as to obtain a plate 0.5 cm thick. Put a dry leaf or an artificial leaf with a clear relief on top.

Roll out the second blank on top and leave a kind of puff cake to dry a little. Now you can separate the two parts of the mold and remove the leaf.

Note!

We leave everything until the final drying, after which you can correct the edges of the forms. They will turn out elastic, will bend well, give a clear impression.

We simplify the process of sculpting petals

A lot of flower petals are always required. For them, you can also make a mold, and speed up the sculpting process.

From polymer clay it is necessary to sculpt a complex figure: its upper part resembles an elongated leg, and the bottom looks like a thickened drop. Press the workpiece against the table, making the base flat.

Now, with a thick needle or toothpick, we begin to draw longitudinal stripes on a flat drop. They should be of different lengths, interrupted and bent. After that, we send the stamp to the oven and start using it immediately after cooling.

The notches made with a needle imitate the natural pattern on the flower petals well. Add to this the leaves made with the help of wonderful homemade molds, and you can collect chic bouquets.

Note!

Do-it-yourself photo of molds

Often, to create a particular craft, you need original molds. This is the name of small silicone molds in which you can put various kinds of materials for their further solidification and use for various purposes.

Of course, you can buy them in the store, but, unfortunately, it is not always possible to find what you need. In this case, you can try to do do-it-yourself molds. Homemade molds are suitable for making figures from polymer clay, gypsum, mastic, soap and much more. They can also be suitable even for baking in the oven. In this case, when choosing a material, preference is given to the most heat-resistant.

1. Do-it-yourself sealant molds

The easiest way to make molds yourself is from silicone sealant. This material is the cheapest of all possible. It also meets all the necessary requirements that molds must have to create figures. Such a sealant can be bought at any hardware store. Preference should be given to neutral or acidic formulations.

There are also sealants with filler, more often with acrylic, it is better to refuse them, as they can crack during operation. Sealants come in completely different colors, from transparent to black. If you need to make a mold so that it can be baked in the future, you should choose heat-resistant sealants that can withstand temperatures of 200-250 ° C.

To create a mold from a sealant with your own hands, you will need:

Sealant.

Sealant gun.

Starch or powder.

Shape to extrude the shape.

Gloves.

Container for mixing mass.

Plastic spoon.

Soap solution.

All materials must be prepared in advance, as the sealant begins to dry very quickly. It is better to take 2 pairs of gloves, because they can tear, and it is not recommended to knead with bare hands at the first stage. It is better to use a container as a container, which can later be thrown away. You can also do without it, doing all this on a prepared surface (plastic or wooden board).

1. First of all, insert the sealant into the gun and squeeze a small amount onto the prepared surface or into a container.

2. Next, sprinkle it on top with starch or powder. What kind of starch will be, it does not matter at all. This must be done in order for the sealant to create do-it-yourself mold thickened a little, as it is quite liquid itself. Starch or powder will need approximately the same amount as sealant.

In extreme cases, you can use ordinary flour, but the result will be a little worse.

3. Then, using a plastic spoon, knead the mass. When it thickens a little, you should continue to knead with your hands.

4. Form a ball from the resulting mass and press it with the palm of your hand or a flat surface to the table. It turns out a flattened circle. Its width and depth should be slightly larger than the shape with which the desired shape will be extruded for do-it-yourself mold from sealant.

A teaspoon of detergent is diluted in a glass of water. This is necessary in order to make it easier to remove the figurine after the mass has completely hardened.

6. Now you should press the prepared figure into the mass of sealant. This should be done by pressing evenly on the entire surface.

7. After that, you need 12 hours to dry completely sealant mold.

8. Then the figurine must be carefully removed and the work can be considered finished.

The result is a cast that can be used as mold for mastic or polymer clay, as well as mold for soap and much more.

2. DIY silicone molds

For creating do-it-yourself mold you can also use Moment silicone. The technique of work is exactly the same as with the sealant. The difference is that silicone hardens a little faster and cannot be used for polymer clay, as it has lower heat resistance. silicone molds well suited for forming the shape of soap or bath bombs, and how to make them, you can read

Molds, which were originally used for ceramic floristry, conquered foamiran masters, greatly expanding their capabilities. So, thanks to these simple, embossed forms, you can quickly and easily get a clear, natural relief of flower petals and flowers. What are molds and make these useful forms with your own hands - read below.

So, mold is a cast, flat mold for making relief elements on the front surface of a foamiran blank. Weiner is a voluminous silicone mold, which makes it possible to obtain not only convex veins, but also to make the edges of foamiran blanks curly. Such forms are great for creating floral elements of plants with curly petals and leaves (rose, dahlia, lily, etc.).

There are a huge number of Moldovans and viners, and sometimes it is incredibly difficult to choose the right one from such a variety. What molds are better? Experienced craftsmen say that the best forms that give clear impressions and do not tear the fom are Thai. But the price of such products is quite high.

If there is no opportunity to purchase a ready-made mold, then, for the first time, you can replace it with improvised means (for example, plates with a floral texture, a cutting board, ceiling tiles). Some craftsmen adapted themselves to work with needles and toothpicks, applying relief by hand. But, it’s better to make an element with your own hands: the cost of such a mold will be much lower than the cost of purchased ones, and the result is much better than from improvised means.

Mold for flowers from foamiran

The simplest, most versatile way to make molds with your own hands is with the help of viscous and plastic polymer clay. For work, we need: fresh polymer clay of any color, a live leaf with well-protruding veins (it is better to choose blackberry, raspberry, begonia leaves), a clerical knife or a thin blade, ceramic tiles or unnecessary faience utensils, a metal baking sheet for baking clay, a needle.

Making molds:

1. Roll out the clay in a fairly thick layer.
2. We apply a sheet to the clay and press it tightly with our fingers, in order for the veins to be better imprinted, we pass over the sheet with a rolling pin from above.
3. We hook the leaf with a needle and carefully remove it from the workpiece.
4. We cut off excess clay with a clerical knife or blade, giving the workpiece the shape of a leaf.
5. We send the negative mold to the oven and bake according to the instructions for the polymer clay used in the work.
6. Roll out another layer of clay.
7. Wet the cooled negative with water (from the side of the veins) and lay it on the rolled out layer.
8. We press it with our fingers and roll it out with a rolling pin.
9. We separate the negative and cut off the excess from the workpiece.
10. We send the relief form to the oven for baking.

After the double forms have cooled down, you can safely use them in your work. In this way, you can make leaves of various shapes and sizes.

If the clay is not viscous enough, you can knead it with your hands using petroleum jelly or a greasy cosmetic cream.

How to make molds for foamiran with your own hands from silicone sealant

Another way to create molds for making flowers from foamiran is with the help of silicone sealant, which allows you to transfer the relief from any voluminous leaf. Making a silicone mold is quite simple: for this we need a sealant, a small spatula, a transparent sheet from a stationery folder, an impression sheet, scissors, a sheet of A4 paper.

Let's get to work:

1. We attach a sheet of paper for taking an impression to an A4 sheet and circle it.
2. We remove the leaf and put a transparent sheet on the pattern.
3. Squeeze out the silicone into a container and use a spatula to transfer it to a transparent sheet so that its size corresponds to the size of the sheet for taking the impression.
4. Lubricate the leaf with oil and apply to silicone.
5. We leave the silicone to dry for several days (from two to four, depending on the sealant).
6. After drying, with a needle, remove the leaf from the silicone.
7. With scissors, we give the silicone molds the shape of a leaf.

The work is ready: as a result, we have convenient, high-quality, double-sided forms for quickly creating attractive, natural foamiran leaves.

With what else can you make molds for foamiran

You can quickly and easily make molds from corn or potato starch and ordinary silicone sealant (available at every hardware store). In order to directly start creating stencils, we need to prepare a mixture for taking impressions: in an unnecessary container, we knead the materials in a one-to-one ratio, first with a wooden stick, and then knead the mass by hand until completely homogeneous (we put on disposable gloves to protect our hands).

Let's get to work:

1. Separate a small part from the total mass, form two balls of different sizes from it (one is larger than the second).
2. Roll out one ball with a rolling pin so that you get a flat surface 5 mm thick.
3. Top with a dried leaf of the desired plant or a handicraft store-bought artificial copy with a good texture.
4. Roll out the second ball on top of the sheet.
5. Set the workpiece aside: let the mass grab well.
6. After some time, separate the top layer from the workpiece and remove the sheet.
7. Leave molds to dry. If necessary, you can adjust the edges of the molds to the size and shape of the sheets with scissors.

Even a novice master can easily repeat this master class, and the resulting molds will not only come out inexpensive, but will also give high-quality prints due to their elasticity and flexibility. You can use these forms more than once.

Molds and viners are incredibly useful stencils for working with foamiran, allowing you to easily and quickly transfer the relief to the workpiece. Such forms can be purchased in stores, or you can make it yourself, saving, at the same time, a little money. Make molds and viners with your own hands, and get original, attractive, expressive textures to create high quality works!
