Large boulders stacked stepper garden paths and rest areas. However, to find or buy such a stone is not so easy or prohibitively expensive, so it’s easier to fake it with concrete. It is not difficult, but the result will exceed all expectations.
- riprap stone;
- the dye to the concrete.
Manufacturing process simulation
To simulate flat stones, you need to prepare the form. It is under every stone separately of a flexible but sufficiently rigid tape. Tape width should be at least 5-6 cm In its as suitable strips from old window shutters. You can just cut into strips of trimming linoleum or other similar material. The edges of the strips are connected in a ring stapled or glued with tape, tape. Rings are made of irregular shape of different sizes, and laid on the prepared surface with a gap of 5-10 cm.
Then they are fixed by pins and wire.
Next, preparing the concrete substrate and is placed on the bottom of the form.
Need a thick mixture. It is composed of sand, cement, water also does not hurt the rubble. It is desirable to add a plasticizer for paving, which will increase the plasticity of the composition, as well as strength, density and frost resistance after hardening. Not to bother with proportions, you can just buy ready mix for the screed in bags and dilute it with water. The second substrate is filled, but painted a piece of concrete without the gravel. It must first be stirred without dye, and then add the paint and stir it unevenly to get a divorce.
Putting the concrete on the sides of the form, you must create a relief under the stone. To do this, he leveled his hands in a crumpled trash bag. Then you need to compress the shape of a circle to round the edge of the concrete.
30-60 minutes form is removed. The surface of the simulated smoothed with a wet brush with stiff bristles. It blurs the contours of the concrete paint will give it the necessary realism. If you want to make the stone even more unusual, the individual plots can be colored with a different color, for example yellow or brown, if the main color is black.
The next 5 days to moisten the imitation water to cement firmly grabbed the stone is not cracked. After that, the joints between the stones should be covered with gravel. It is desirable to paint the concrete with a protective composition. This prevents shedding and gives a light Shine wet stone.
