Cheap, reliable DIY chemical anchors

For fastening to walls made of loose materials, as well as concrete structures close to the edge, it is best to use a chemical anchor. Unlike a spacer, it does not break out or chip the base, so choosing it is a guarantee of reliable fixation, even under heavy load. Since the price of chemical anchors is steep, they can be made from cheaper materials that are easy to obtain.

Materials:

• automotive putty;
• sand;
• syringe;
• threaded rod.

Manufacturing process of chemical anchors

Before making the composition, you need to pre-drill all the holes, blow them out of dust, and also prepare threaded rods. Only after this can the substance be mixed, as it hardens quickly.

Next, two-component automotive putty is mixed in a small amount.

A little sifted sand is added to it.

The composition is drawn into a syringe and squeezed into the holes.

After this, a little mass is applied to the studs and they are screwed in. First cut the hairpin into pieces.

After just a couple of hours, the putty will hold in such a way that you can attach it to the anchors.
