For Working with Fiberglass and Polyurethane Forms


Icon Poly - Suggestions for Artists


1. Lightly sand entire surface with 100 – 220 grit prior to painting. This sanding is more to clean the surface,

not to remove the prime. Do not over sand. If primer is flaking, wipe with denatured alcohol or a painters

tack cloth. Re priming is not necessary unless your paint of choice recommends it. In that case follow Paint

manufacture’s instructions.


2. Wear plastic gloves when doing this and when touching the raw sculpture after sanding. This will keep oils

from your hands off the surface which could cause an adhesion problem when painting. Do not wear latex

gloves because of the powder residue that would remain on the sculpture. Icon Poly suggests loose fitting,

food handler gloves. They are available at Sam's and possibly at Wal-Mart. Icon Poly purchases theirs

from a food supply company.


3. If any primer flakes off when sanding, sand back to where the primer is stuck, abrading the raw resins.

Then re-prime that area. They suggest using any brand of Gesso and almost all paint manufactures have a


GRADE PRIMER i.e. Rustolium, Kilz, Zinner, Krylon.


4. Using acrylic paints is HIGHLY recommended. Most brands work fine - even the acrylic craft paints from

Hobby Lobby. They recommend staying away from oil paints if you do not have a lot of experience with

them. If you have specific questions please contact Icon Poly.


5. If a drill is needed for embossing or any other creative reason, Icon Poly suggests a dremel type rotary tool.

They are available at Wal-Mart, Home Depot, Lowes and Menards.


6. If an artist plans to cover the entire surface with materials other than paint, in the case of tile or mosaic

work, an artist should request an UNPRIMED sculpture immediately following selection notification. Artists

interested in mosaic surfaces should contact Icon Poly for information for best adhesives, grouts, and



7. When attaching items with adhesive be sure to sand or rasp down into the material of the sculpture. Do not

glue to the primed surface.


8. If attaching items, they recommend using physical attachment (i.e. screws, bolts) in conjunction with adhesive

attachments when possible, using both together to create a much more durable piece. A moldable material

called Apoxie Sculpt is available at which is

similar to the look and feel of the fabricated urethane tree. If you intend to change the structure or add to

the structure, please contact Icon Poly for Guidance.


9. They highly recommend structural urethane adhesive when bonding things to the sculpture. Several companies

make these such as 3M, U-Pol and Norton. These are normally found at auto body supply stores.


10. After your sculpture is complete, whatever the finish, you must apply an automotive grade clear coat or

equivalent product recommended for protection for UV and exterior elements. Three coats encouraged.

Always follow application instructions on the project you select. Be sure to test for compatibility in an inconspicuous

area prior to clear coating the entire sculpture.
