Nice Material

As an amateur I found this tape to be perfect for the corner reinforcements on the battery platform that I am reconstructing. Should come in handy once I get around to building my dinghy!

3 layers of ""glass at once

Because it's three layers, it's not as easy as a cloth to wet out, but it does wet out well, but not clear. Good for reinforcing corners.

Really heavy duty

We used this when replacing the floor in a 1970's fiberglass boat. Gave very good support along the edges.

Thick and strong

9 years ago
Most of the bulkheads in the 23 foot sailboat I bought were completely rotted through. I used this cloth to tab the bulkheads back in. It is very thick and I feel that it only needs one layer. It conforms very well to the contours of the hull, usually only needing one cut to lay completely flat. It is easy to wet out. I filleted with collodial silica before laying the glass down. On the second bulkhead I put down the fillets and the fiberglass at the same time to save myself some tedious sanding work.

Perfect for fiberglass repairs

I like this Biax tape for boat fixes and upgrades. Tape is easier to work with than cloth (less cutting) for smaller repairs. It does a good job for reinforcing panels and tabbing bulkheads. I prefer epoxy for the strongest bonding.

Q: is it best to wet out surface or cloth first to avoid a bubble going around coaming edge?

A: Hi Jim, it doesn't really matter which one you wet out first. You want to apply some resin to where the cloth tape will go, and wet out both sides of the cloth itself before you apply it, then using a roller or spreader, work any air bubbles out of it. If possible, using the vacuum bag method also helps remove any air bubbles or voids if that is a major concern for your project.

Q: Is this tape made from DBM1208 or DBM 1708. I'm assuming 1708 since it mentions 17oz, but I want to be quite certain. Thanks.

Q: I used biaxial tape for my first homebuilt boat. The tape had strands of what I think was cotton thread to hold it together. The threads left high ridges that were nearly impossible to get rid of other than substantial filler over the joint. Is there a type of biax tape that does not have this?

A: I have not seen a biaxial glass that does not have that weave of thread. I just had the exact same happen on some supports I did,I sanded it as good as I could,then gelcoated it,sanded it again and gelcoated once more and it was fine. you could do filler as well.but I'm not a big fan of fillers.Its quite possible that there is a tape that doesnt have those threads.or possibly a better quality tape might have a tighter sewing? Good luck.

Q: I need some 3-4 oz fiberglass strips to edge the hatches on a strip-wood kayak I'm making. I've bought fiberglass tape before that has a hard ridge on the edges. Will any of this tape work, or should I just get cloth and trim the edges? Thanks

A: This is an excellent product... It consists of +/-45 biaxial cloth stitched to CSM. It is ideal for tabbing in bulkheads and very easy to work with compared to woven cloth. As far as I am concerned, there is no raised [woven] edge as with conventional tape. However, this material is much heavier, total weight 25 oz/sq yd, than what you specified. It is more oriented to structural rather than finish work. So, it might not be the right choice for your application.
