Tulle + TBIII + Paint: A Promising Sheathing Combo

In our endless search for cheaper solutions to common problems, we seem to be closing in on a minimum. Specifically, in regards to a plywood sheathing system.

Previous posts - More Than One Way to Sheath a Boat and Deck Sheathing: Alternatives to Fiberglass and Plastic Resins - explored alternatives we've tried. Our state-of-the-art is woven acrylic fabric (sometimes sold as 'Dynel') providing a matrix for TiteBond III water-based (but 'proof') glue.

Problem is, formerly cheap acrylic went from about $5 to $25 per yard (yikes!) over the last ten years.

So we hunted around. Synthetic fabrics of every stripe were durn expensive, and we were reduced to collecting second-hand sheets (not a bad option, but take a lot of piecework).

And there was Tulle (bridal veil material)! We found some made of polyester that covered the horizontal decks of our new boat with plenty to double it on high-wear areas. All for about $1 per yard (less in quantity) through Amazon. TiteBond III is still cheap as paint.

Tulle wets down well, and the drying TBIII first layer has little problem pulling it flat (but help it along creases by spreading flat). It conforms well to tight-radius exterior and interior edges. With two coats of TBIII and topcoat of paint, the result is a moderately textured surface over a thick, reinforced film of hard-set glue protected from UV by paint.

So Tulle looks good as an inexpensive alternative to other synthetic fabrics. Time will tell... the gold standard is about 15 years.

Our Application Procedure:

1. Prep surface (smooth and tack-free)
2. Pre-cut Tulle to fit
3. Wet down Tulle with water (soaks the wood under)
4. Immediately brush TiteBond III (ample, but don't sweat it)
5. Let dry (will draw down Tulle for initial bond)
6. Lightly sand sharp points, edges or ridges, if any and tack
7. Apply second coat of TBIII (ample, but brush out to preserve weave)
8. Let dry
9. Prime while still 'green' (within 24hrs)
10. Topcoat

One cool aspect is that, with judicious selection of products and a warm, breezy day, starting with a prepared deck we can (theoretically) manage five coats (2xTB, 1x primer, and 2x topcoat) in one long summer day. And much of that is kicking back and watching it dry.

Cheap AND efficient!
