How to make a form for paving slabs

Before the new owner of the country area or his home is often a problem, the better the paths and space near the house, so as not to apply trash inside the room. Most use paving slabs for this. However, it is not possible to afford it. Therefore, make tiles with your own hands. And the first thing that is necessary for its production is forms. Today, how to do them, we will talk.

1
Materials

Silicone, polyurethane, plastic can be used for forms. All listed raw materials have a number of positive characteristics, such as: durability, ease of use, flexibility, strength. In the usual building supermarket, this material for forms can not be bought. But it is probably purchased directly from manufacturers through online portals. If there is no such possibility, then make shapes for filling from wood. A qualitatively made form will serve for a long time, with its help you can produce from 500 to 1,000 castings. Before proceeding with work, you will need to prepare the following tools, materials:

screwdriver;
nails, screws, metal corners;
tree (boards);
hammer;
raw materials;
electrolovka, level gauge, electric drill.

Plastic forms

First, make a matrix. Draw the drawing and accurate sizes of the figure. Then make a frame from the tree, take into account the allowance, approximately 2 centimeters (in length and width) so that the tile turns out the desired value, forms. Then in the matrix, fill the molten plastic. It is important to know that specialized raw materials for the manufacture of figures toxic. And when weaving, the following conditions must be observed:

use PVD, polypropylene, PND;
heat the mass gradually, otherwise, when a high temperature is reached, thermoplasts can lose their properties;
make smelting in a closed ass, so that there is no access to oxygen.

After 55-60 minutes, plastic freezes. It is necessary to remove. Disassemble a wooden frame (unscrew the screws), pull out the form. So that it was smooth, process the sandpaper.

Silicone forms

If you are connoisseurs of a variety of designer reliefs, then silicone forms for you. The only drawback of them is a shortage of hardness. In the production of tiles, the sides of the product are often blowing out or pushed. To make a silicone figure, prepare a matrix, sculptural plasticine, raw material (for wear resistance to silicone add a hardener, catalyst). Plasticine cut out the drawing inside the frame. Then degrease the finished matrix, lubricate with vegetable oil, pour the finished silicone thin jet. Expect drying will be required twenty-four hours.

Forms of wood

Figures for tiles made of wood are made according to the likeness of the matrix. The configuration can be diverse, also drawing inside the product. The main thing is to fasten along the corners so that then in the production of the tile it was possible to decompose it. Otherwise, when issuing tiles, problems will arise. When the product is ready, it is problematic due to the stiffness of the structure.

Advice

To serve for a long time, follow the recommendations:

do not store them near heat sources, optimum storage temperature - 18-20ºС;
after filling the concrete, wash and thoroughly clean the residues of the concrete mix;
it is impossible to pour hot concrete in the figure, if it is made of silicone, plastic, etc.

If you wish to lay a tile of the whole yard, then use a lot of forms, not one. For the edge of the edge, make half the molds in the case when the drawing "obliges".
