How to glue the foam to the concrete on the ceiling?

If concrete structures have long been famous for their strength and durability, they, unfortunately, have low thermal insulation properties. It is easy and effective to solve this problem sheets of foam plastic, which are now widely spread housing and industrial structures. But here's the difficulty - you need to know exactly what you can glue the foam to the concrete ceiling , because this material is afraid of solvents, gasoline or acetone. Here we will look at the best adhesives that are used in the installation work with this excellent material.

How to glue foam to concrete?

  1. A glue mixture of dry powder . There are special adhesives for expanded polystyrene plates (Moment PPS, Dobs Therm Fix, Glue for foam plastic Anserglob BCX 39 and others). Also suitable for foam plastic facade adhesive and adhesives for ceramic tiles. You will need an additional tool - a drill, a nozzle, spatulas, buckets. The operating time here is somewhat limited, it does not exceed 2 hours, after which the solution becomes viscous. Re-dilute it with liquid is not recommended.
  2. Silicone sealants or liquid nails . These adhesives are supplied in tubes, for operation with which mounting guns are needed. They harden fairly quickly (about 30 minutes), have a good heat resistance and moisture resistance. Due to the fact that the composition of sealants are harmful components, you have to work with gloves. This method is suitable for exceptionally flat surfaces.
  3. Glue foam in cylinders . You can use Ceresit CT 84, INSTA STIK Adhesive for foam.
  4. MONTAGEFIX-ST and others. Additional tools for this method are a mounting gun and a special rinse-cleaner. Considering all the ways how to glue foam to the ceiling, we can state that this method is almost ideal. A balloon of quality foam will replace the glue bag, and it will be easier to work with it. In addition, it perfectly closes all gaps and joints, providing better thermal insulation. One drawback of foam - the cost of the material is higher than that of the powder formulations.
  5. Practically all listed methods, than to stick a foam plastic to concrete on a ceiling, it is possible to use in our business. The difference here is in the cost and convenience of work. The only condition - fix for reliability sheets dowels-umbrellas, and the resulting slots and joints handle adhesive compounds. Lastly, a reinforcing mesh is applied, which is fixed to a special solution, and only then is the final finish already carried out.
