The best kit to create alginate molds and plaster copies

In this Feroca article we have thought of the little ones in the house to make these days of confinement more enjoyable, since all the materials we are going to use are harmless and free of toxic agents, both for the skin and for the respiratory tract.

andnbsp;

That is why we have created this special kit to make small molds of hands and feet that we describe below, to enjoy and create together with the smallest of the house.

andnbsp;

The best starter kit for making hand, foot and more molds

andnbsp;

The components that make up this ideal fun kit for the whole family are the following:

andnbsp;

Alginate

andnbsp;

Alginate is a specific material for making single-use molds of parts of the human body without damaging them.

The best? It is created from algae and mixed with water, all natural and biodegradable materials, suitable for the use of the smallest of the house.

andnbsp;

Our alginate has two versions:

andnbsp;

1. A fast, for professionals and quick molds of faces, which is the Agacast Fast. It has a curing of between 3 and 4 minutes depending on the temperature of the water.

andnbsp;

2. The other version is the Algacast Slow. Designed for beginners, courses, children's classes... It has a wider time frame of about 9 to 12 minutes, depending on the temperature of the water, which we will explain later.

andnbsp;

Plaster

andnbsp;

Plaster is a very economical material to reproduce decorative pieces with a great result and a high detail.

This plaster that we are going to use in the kit, is especially a very resistant plaster with a high level of detail.

This is a harmless material, you just have to take some clear precautions when working alone or with children:

andnbsp;

• It is a powder, so it should not be shaken or sprinkled without caution.

andnbsp;

• When mixing, it must be done carefully, as its prolonged use in contact with the airways can be harmful. As the amount is small, there is no problem, unless a very large dust cloud is generated.

andnbsp;

• Another indication is that it dries out the skin. The use and mixing by hand, which we do not recommend, dries the skin a little, so it is recommended that after use the hands are washed well and then cream is applied to this area of the body to avoid dryness.

andnbsp;

Tools to prepare the mixture

andnbsp;

In addition to the materials mentioned above, the molding kit also has a wooden rod to remove and a transparent container to make the mixtures.

andnbsp;

As you will see, it is a perfect and complete solution to entertain us as a family. In fact, we could assure that it is among the best activities to do with children at home . andnbsp;

andnbsp;

Super guide to make molds of hands and feet with your Feroca kit

andnbsp;

1. Choose body part and determine the best position for an amazing result

andnbsp;

To begin with, we must think about the position that our hand, foot or part that we want will have, taking into account possible bubbles. The more stretched the better, although it can always be retouched at the end.

andnbsp;

2. Prepare the mixture to make our alginate mold

andnbsp;

andnbsp;

Once the position is decided, we prepare the alginate mixture. For every 3 parts of water one of the alginate powder. You can measure it with glasses or with recycled clean containers, the important thing is that the ratio is 3:1.

andnbsp;

It is very important that the mixture is done well, because if there are not going to be many lumps that make it difficult to register. The process is as follows:

andnbsp;

Step by step to prepare the mixture

andnbsp;

• In the container of the kit to make the mold we will pour the 3 parts of water.

andnbsp;

We recommend using warm water, because if hot water is used, curing will be faster and, if it is cold, it will take a few minutes.

andnbsp;

• And then we are going to incorporate the alginate into the water.

andnbsp;

andnbsp;This material must be poured little by little while the water is mixed. In this way we will avoid lumps of alginate that do not mix well.

andnbsp;

• There is a previous step that is optional. It consists of straining the alginate, crumbling the possible lumps that there are and, thus, it can be mixed better with the water.

andnbsp;

In this process we can not delay much, since the working time with warm water is 4 to 5 minutes.

andnbsp;

3. Mold creation

andnbsp;

• When the mixture is done, we wet our hand or foot with water and put it in the mixture. Once inside, we open and close our fingers and try to make the record complete.

andnbsp;

We leave it static in the desired position and wait for it to heal.

andnbsp;

• This process we recommend doing it in a comfortable position, either on a table or similar, since you have to be 10 minutes with your hand inside.

andnbsp;

• When it begins to dry, it will acquire a more gelatinous state and texture, until with the complete curing it is a complete gelatin.

andnbsp;

• At that point, you have to start moving your hand and fingers very slightly to unmold (or the part of the body that has been chosen).andnbsp;You have to do it carefully so that it does not break.

andnbsp;

• You will notice how it takes off little by little until you can take out your hand completely.

andnbsp;

Do not worry if you have any hair because it does not tear them off, on the other hand, if you have to be careful with rings, bracelets or jewelry, since they will get dirty and, when it comes to unmolding, they can tear the mold, our recommendation is to avoid them.

andnbsp;

4. plaster casting

andnbsp;

Once we have the mold done, and without removing it from the container, we must make the casting of plaster. This step must be done in the shortest possible time, since after 2 hours and depending on the ambient temperature, the alginate will begin to dry deforming little by little.

andnbsp;

This kit contains a bottle of Ultra cal 30, a standard setting plaster with a special high hardness for sculpture.

andnbsp;

Step by step to make the plaster casting

andnbsp;

For the plaster mixture, it is best to do the same as with alginate.

andnbsp;

• On a glass we pour the water that we believe will occupy the casting.

andnbsp;

• We start sprinkling the plaster little by little (without mixing it, just sprinkling).

andnbsp;

• When the water is saturated and there is a cracked desert effect on the surface, let stand for 2 or 3 minutes.

andnbsp;

• After these minutes in which the plaster is hydrated, mix it well and pour over the mold a little, less than half.

andnbsp;

• We make a light rotomolding so that the plaster registers well all the possible nooks and crannies of the mold and, we finish the casting.

andnbsp;

To facilitate the extraction of possible bubbles, it is advisable to give a few touches on the container so that with the vibration they rise.

5. Unmold our piece

andnbsp;

After an hour we can unmold. The setting time is 30/35 minutes, but in a piece with fine fingers and such fragile parts it is advisable to wait between 45 and 60 minutes.

andnbsp;

andnbsp;

To unmold, you can help yourself with a cutter, but you have to pay attention not to scratch the plaster.

andnbsp;

andnbsp;

Little by little you are removing the alginate in parts in order to obtain the copy of your hand.

andnbsp;

6. Dry the piece obtained with your starter kit for molds

andnbsp;

You will have to let the piece dry a little more after extracting it from the mold, since it still has moisture and will take between 24 and 48 hours to lose it.andnbsp; If you pose it on a terrace or balcony it will dry on its own.

andnbsp;

Just right? A great kit to create tender and unforgettable memories with children.

In addition, if you want to impress all your guests at a party like Halloween, you can do it with alginate. In the following link you will find all the information:andnbsp;Body mold for Halloween
