Abstract
The test piece its added other wood and reinforcement to improve the strength of Compressed Sugi with Elasticity, and carried out tensile strength test and flexural strength test. As the result, after the test piece was impregnated with Moisture Curing Polyurethane Paint its strength and modulus of direct elasticity has improved. In addition, the test piece which have added other wood and the test piece before impregnating with Moisture Curing Polyurethane Paint confirmed its vibration reduction.
