How to Attach Foam to Concrete

Foamboards, or polystyrene foam boards, are a neat, light, and practical alternative for insulating exposed concrete. There is no mess, so unlike fiberglass insulation, this foam is not irritating.

There are other ways to place the boards, yet polystyrene adhesive works rapidly and does not require furring strips on the wall, as nail application techniques do. When placing foam boards, all concrete must be completely dry and crack-less. Once you’ve started, address any moisture issues and seal any cracks.

  1. Place a polystyrene insulation board on the floor, backside up. The rear end is unadorned with wording.
  2. Using a sharp knife, trim a package of the best adhesive for foam board to concrete or low-VOC foam board glue’s tip.
  3. Shatter the foil or plastic seal within the tube nozzle’s base with a long, slender instrument such as a long nail, a skewer, or a rod connected to the side of certain caulking guns.
  4. Place that adhesive tube inside a caulking gun, then push its trigger until the glue fills the nozzle.
  5. Apply glue lines or beads throughout the polystyrene board’s back, separating the beads at roughly 10 to 12-inch intervals. Maintain all beads not much more than 1 inch away from the board’s edges to avoid extra glue leaking out of the side when placed against the wall.
  6. Lift the bonded board so that the sticky side is up against the wall. Push the board against the wall and keep it there for one to two minutes until the glue hardens. If the glue does not cure fast, you can secure it with a 1 1/2-inch concrete nail via the board’s top and another via the bottom. Even though nails can stay on boards, they are simply for temporary assistance.
  7. Seal over through the deep gouges with a substantial amount of adhesive for foam board to cover the rupture and minimize the polystyrene’s insulating quality from being reduced.
  8. Apply glue to the next board’s reverse side, then place it against the walls. Slide the tongue-and-groove corners of the boards together, then hold or fix them using 2 concrete nails. Place the boards throughout the walls using the same method.

Tips for Applying the Best Adhesive for Foam Board to Concrete

  • Push polystyrene board adhesive seam tape over through the seams between boards to secure them for further insulation.
  • Polystyrene insulation is easy to cut. Trimming boards around obstructions and even at the wall end is as simple as using a sharp pocket knife or a thin, portable drywall saw.

So, that is some useful information about the best adhesive for foam board to concrete, including the methods to attach the foam to concrete. If you have some trouble with it, you can contact the professionals for assistance.
