Wood has been used in many industries throughout the ages, as wood began to be used in ancient Egyptian times and from the early ages in their daily lives and in the manufacture of statues, wooden coffins and others. Sycamore wood was also used in many ancient industries. Wood is exposed to many factors of damage such as relative humidity, temperature, light, etc. continuously. As a result, strengthening materials are used to improve the physical, mechanical and chemical properties of wood in general. In this study, Nano Paraloid B72 dissolved in ethyl alcohol at a concentration of 1% and 3% was used to strengthen wood samples, in order to evaluate the efficiency of this material in the strengthening of colored wood through the use of tests and analyzes such as scanning electron microscopy to study changes. surface of samples and color change using CIE Lab system, And infrared spectroscopy to study the chemical changes in the chemical composition of wood and the characteristic spectra of the functional groups of cellulose, hemicellulose and lignin that make up wood. Through the results, Nano-Paraloid B72 is evaluated in the strengthening of colored wood.
