Ask a Question
  • I want to add your color pigment to the layer of fiberglass. Then I'm thinking of adding another layer of fiberglass. On your website help page it says to install the finbox after hotcoating and sanded flush to the board.So should I install the finbox after these two layers of fiberglass? Also, what do you add for it to be considered a "hotcoat"? Thanks

    Install the finbox, plugs, handle, etc. after all the fiberglassing and hotcoating is finished and cured. A hotcoat is epoxy with Additive F added which is brushed onto the fiberglass lamination to seal the board and make it sandable. A full explanation of hotoating and installing fin boxes can be found in our Surfboard Building Guide
    You may also want to invest in a centerfin install jig to route the fin box pocket safely and precicely.

  • Do you have any recommendations for adding color to the SUP? Do you sell colors that will work with this SUP process.

    The easiest way to get color on a surfboard or SUP is to add a colored pigment to the resin while laminating the fiberglass. You can also paint the blank with acrylic paint (2-3 light layers of paint) then laminate the board with clear resin (no pigment) and fiberglass. 

  • I am looking to build two SUPs. I’ve never done this before. What else am I going to need in addition to you kit? Is one layer of glass enough? How about sandpaper grit? Thanks.

    With our Engineered 2# EPS foam you can make durable SUPs with just a single layer of 4 oz x 42" fiberglass on the deck and bottom. SUPs built this way are just as strong as all the chinese pop outs which are the standard for most paddlers. You can always add a deck patch of 4 oz glass to increase the strength if you wish. 

    You can add a deck pad to your SUP or wax the deck like a surfboard for traction (which is becoming a popular option for traction)

    After glassing the board sand with 80 grit, then 120, 150, and 220 grit. This is a typical "sanded finish". If you want the board to be shiney you can continue sanding with 320, 400, and 600 grits then compound and polish the board for a nice shine.

    Read through our Surfboard Building Guide for a complete expanation of the process from start to finish.
