Cracking
Chainsaw carvings are, for the most part, carved from whole diameter logs rather than a slice of a log. It's the nature of a log to check or crack as it dries from the center core. What does that mean to you as the owner of a chainsaw carving? Well… it means your carving is going to possibly crack. It's part of the natural process, so you might as well enjoy it.
Displaying your carving
Your carving is wood. Wood can split, crack, rot, fade, burn and/or be attacked by insects. Putting a little thought into where and how it's displayed can help your carving last for years, or forever.
Do not set your carving directly onto soil, grass, or mulch. A pad of concrete, gravel, or paving stones is better and will help protect the base from water and insect damage. You can buy tack-in furniture feet at your local hardware store to lift the carving up a little — this creates a gap for airflow underneath.
Heat from either harsh desert sunshine or even household heat (indoors) will dry the wood quickly, which causes additional cracking from the center core drying too fast. Avoid these situations when possible, or be prepared to renew the finish more frequently.
Rain is not much of a problem for a properly sealed carving. Frequent drenching with water (irrigation, etc.) increases the likelihood of water damage, so try to display your carving beyond the reach of your lawn sprinklers. Keeping it properly sealed (described below) is very important if displayed in a wet location or climate.
Maintaining the finish
Most carvings are sealed with Marine Spar Varnish or Helmsman Spar Urethane, which can be purchased at any hardware or paint store. Oil-based only! This can be brushed or sprayed on. When cracks develop, use a brush and let the varnish run into the crack to seal the wood. Do not try to fill the crack with varnish — you just want to seal the surface of the newly exposed wood inside the crack.
It's recommended that any carving displayed outdoors be re-sealed with spar urethane each spring and autumn.
Spar urethane is available in gloss (shiny) or satin (no shine). If your carving isn't shiny and you'd like it to be, paint the gloss spar urethane right over the satin.
