How to make a gun for quickly applying plaster and putty

Plaster and putty can be applied to walls using a compressor. This is the easiest way to achieve uniform distribution of the composition over the surface. To do this, you need a special gun, which can be quickly assembled from plumbing fittings.

Basic materials:


  • 3/4" tee;
    3/4 inch tee

  • blow gun;

  • 3/4 inch nuts - 2 pcs.;
  • nut 1 inch;
  • drives for the meter – 2 pcs.;
  • plastic funnel with thread;
  • thin tube.

Plaster gun manufacturing process


The spout of the blow gun is removed. A washer of a suitable size is placed on its thread.

Opposite it, a squeegee for the meter is screwed on, with a piece of tube pressed inside. In this case, an aluminum ski pole was suitable.

With this gun you will be able to apply liquid plaster, including decorative plaster, as well as putty, very evenly. If the volume of the compressor receiver allows, then by installing a wider nozzle, you can achieve very good performance.

      A spatula is a spatula, but the word “putty” is contained in the Russian language dictionaries published by the Russian Language Institute of the Academy of Sciences and other similar specialized institutions.
