Silmar Resin 249A
Silmar 249A is a resin used in surfboard building. It is a low viscosity resin generally used for laminating cloth to build a surfboard. This resin requires wax for the final coat to be able to buff and polish the board. This last coat is what is called the hot coat. This resin is blue in color but dries to a clear hard durable finish. Tack free additive sold separately.
Recommended you add hardener at 1% or 10cc per quart. This gives you approximately 20 minutes of working time.
We offer three different sizes of hardener with your resin.
The 15cc is enough hardener for a quart at 2%.
The 30cc is enough hardener for a gallon at 3/4%
The 60cc is enough hardener for a gallon at 2%.
If you are glassing below 75 we suggest getting the 60cc per gallon that way you do not run out of hardener.
Please check the mek chart prior to ordering so you get the right amount of hardener. If you have any questions please contact us and we will be happy to help. 772-464-0808
