How To Install Foam Shapes

Standard Foam Shapes Instructions

  • Sizes are as follows: First size number is “A” measurement, second size number is “B” measurement as per diagram below.
  • All shapes come in 96” (8’) lengths standard, but can be cut to 48” (4’) lengths as well.
  • Arches can be custom made to order for all standard foam shapes. Only true radius arches can be made.
  • Columns come cut in two halves with the center cut-out as shown in this catalog. Columns come in 96” (8’) lengths only.
  • Some shapes can be “flex-cut” on the back side of the shape to be able to flex for surfaces that require bending of the shape. Ask Somar Industries LTD. For more details.
  • Many other custom shapes and sizes can be custom made to order; Other Column Styles, Balusters, Different Capital and   Base Designs, Quoins, Keystones, Wall   Plant- Ons, Dentils, Sills and Wall Caps. Consult with Somar Industries LTD. For the unlimited design options you have.
 

How to Coat EPS Foam Shapes” with Unicoat Stucco Stystems Unibond Foamkote

The UNIBOND FOAMKOTE system is a fast and economical way to apply and finish expanded polystyrene foam shapes. It is comprised of Portland cement, polymers, sand and other ingredients to make an extra durable and long lasting adhesive and basecoat material.  It is always recommended to have a professional plastering contractor apply these architectural foam shapes, but if you want to tackle this project yourself here are a few basic steps on applying your own foam shapes.

 
  1. Always prepare work area with protection from falling or splattering material, UNIBOND will adhere to most any surface and must be cleaned with damp rag immediately before it dries.
  2. Mix UNIBOND as per instructions on the bag, to adhere foam shapes to substrate, make mix same consistency as that  of pancake syrup, thick but flowable. Read instructions on bag for application on proper substrates. Both UNIBOND Coarse and Smooth can be used to adhere foam shapes.
  3. Spread UNIBOND on back of foam shape that will be in contact with substrate, spread a layer approximately 1/4” thick over entire surface of back of foam.  Make sure substrate is free of debre and loose dirt. Press foam shape firmly onto surface, larger shapes may need to be tacked on with a nail to hold its position until material dries.
  4. Always use a level or chalk line to make sure you are nice and straight.
  5. To place the next continuing piece, follow step (3) but also butter end of foam shape that will be butted up to piece that is already in place. Only apply a small amount as not to get excess UNIBOND on front of the foam shape.
  6. When making corners, always cut your pieces to fit before applying UNIBOND.  Foam shapes are cut in the same  manner as wood moldings; they can be cut using a fine tooth handsaw or long sharp knife.
  7. After all pieces are in place and left to dry for at least 24 hours, you must sand down any uneven places along the joints  where two pieces are joined. This can be done using a 50 grit or coarser sand paper. Then proceed in mixing UNIBOND Coarse to a pancake batter consistency. Using a fairly good quality brush, apply a smooth but even coat over entire foam surface. Make sure no white from the foam is showing. Apply a 2” wide piece of fiberglass tape over  joints and embed it with UNIBOND mixture.
  8. After it has dried for at least 24 hours, apply second coat using UNIBOND Smooth in  the same consistency and manner over entire area until a smooth surface is achieved.  It is very important not to over thin material, you must achieve a  1/16” on each coat for a total 1/8” overall thickness of material.
  9. Once material has dried for at least 48 hours, then a topcoat of a good quality latex house paint can be applied. But for a better looking finish use a coat of UNICOAT Acrylic Stucco Finish Fine brushed on in the same manner UNIBOND was applied. And now you’re done!
