Suitable for application on wood are alkyd, alkyd acrylic, alkyd polyurethane, polyurethane, polyester silicone, epoxy, latex liquid rubber, and vinyl paints. Success, however, will depend on how well the wood surface has been cleaned, sanded, and prepared. Primers and fillers should usually be of the non-oily type and preferably of the same brand as the final paint. A wood bottom may be treated with any of the antifouling paints or with a hard non-toxic racing surface if the Boat will not be left in the water between uses. Varnishes, whether tung oil and phenolic resin types or the newer synthetics and two-part epoxy systems, require careful application. Follow instructions as to surface sanding and bleach-
ing if brightwork has weathered. Then, on a nearly windless day with the right temperature, apply the needed number of coats.
The chief purpose of the tiles is to carry air to the roots, but they also serve to drain away any superfluous water and also provide (through the gridded surface openings) a ready means of watering and fertilizing the tree. Watering in droughts, and annual fertilization are helpful, too. • |
