Email Q&A: Cost of Urethanes?
Question: 3/1/06: Thanks for the information from your site on climbing holds. I have not had a chance to make any yet. I have just finished making some molds. The question I have for you is about the cost of urethane. I have been on the web site of Alumilite. They have a nice article on how to make climbing holds with there products. They gave a sample formula for calculating the amount of resin needed for a mold. Basically a 4*3*2 in hold would use about 13 oz of resin. This size hold then would cost approximately $15 to make. From what the company said on the phone most of commecial hold companies buy mass quantities of this stuff. This makes perfect sence. Is this just overpriced for the resin or are there cheaper alternatives to make urethane holds? Thank you very much. Dave Reply: Hi Dave. Sorry it’s taken so long to get back to you.
