Glue problem is a classic problem in the furniture manufacturer. This problem is often encountered in the manufacture of furniture. Glue that is left on the wood surface will make spot mark or splotchy. This glue mark may not so obviously look in the unfinished, but they will be clearly visible after it is finished. The glue splotches will ruin the appearance of finishing, since that it has to be cleaned as far as possible. The glue that is used for assembling has to be strong enough to make an unseparated bond between each component in the furniture product. The glue cannot be resolved after it dry. Since that the glue is difficult to be cleaned with thinner; the method to cleaning the glue is by sanding the wood
Cleaning the glue splotches is usually done by sanding before the finishing process begins. Scrapper or knife can be used to scrap the thick glue splotches, before it sanded to clean the glue mark. The fact the glue mark is rather difficult to be viewed in the unfinished wood. Mostly the glue spot is found after the wood is stained. We can apply a thin stain to help find the glue splotches in the sanding process. This method is also help to find the other imperfectness in unfinished wood such as: the sanding mark, small dents, uneven surfaces, etc.
Some furniture manufacturers even chose to clean the furniture glue mark after the first stain application. The unfinished product after being sanded are taken to the finishing room for first stain application, then after that the furniture are reviewed and rechecked to find the unfinished problems such as: glue marks, scratches, dent, etc. The problem then are revised and touched up, and then the products are sent to the next finishing process. Some factories choose this system since it makes the process production quickly run.
The sanding to remove glue stain is tough process. The form factor of the furniture make the sanding is difficult to be done perfectly. Therefore the best way to clean the glue is to wipe it or resolve the glue while it is still wet. It has to be done in the assembling process. After the component are mounted and assembled, then the glue excess has to be cleaned. The wet glue is can be easily cleaned by thinner or water, but when the glue is dry the cleaning is become difficult.
Fixing the glue problem in the stain process
Here are the things that need to be done to minimize the glue problem.
- Make sure the component are precise before assembled.
- Provide room to accommodate the glue excess in the assembling process.
- Use the proper glue with the right mixing ratio.
- Provide water or paint thinner and a rag during the process of assembling.
- Work carefully and discipline.
