How to make your own woodworking putty

After the gypsum putty is dry, you can officially make the putty. Note: The putty needs to be scraped three times and it must be completely dry before proceeding to the next process. Observe whether the color of the wall is consistent and whether there is "sandpaper sticking" when polishing. When sanding, use a strong light to polish at an angle. It is recommended to use 360 ??grit sandpaper on the top surface.

1. Shovel the wall skin

Do a slight wetting test on the wall in advance to check whether the coating adhesion of the wall is qualified. If the conditions are not enough, it must be shoveled Wall covering.

2. Sealing glue

First apply sealing glue 801 on the wall to strengthen the bonding force between the putty and the wall. If you encounter an old house, it is best to apply a layer of interface agent to increase the insurance factor.

3. Elasticize the thread from both sides at the inner corner

At the inner corner, stretch the thread from both sides. At this time, pay attention to the verticality. At the outer corner, just use the support rod directly. First, use gypsum powder and 801 glue to prepare the gypsum putty and straighten it all.

4. Wall leveling

First check whether there is any hollowing in the wall. The method is very simple. Use a small hammer to hit it and listen to the sound to see if there is any hollow feeling. Then find a slightly longer aluminum alloy ruler to check the recessed parts of the top and wall, mark them, and then fill them up with gypsum putty.

Precautions for making putty

If the base layer has strong absorptive properties, first use a primer to seal the work to avoid The rubber inside the putty is absorbed too much by the base layer, affecting adhesion. When scraping, pay attention to the inclination of the tool, and the force must be even to ensure the putty is full.

If the putty shrinks too much, it will crack and fall off. Therefore, it should not be too thick when scraping. Try to use 0.5~1 mm. Do not scrape back and forth too much at one time to avoid curling and falling off.

Choose suitable putty and scraping tools according to the performance of the paint and the condition of the base layer. During the construction process, use a scraper to fill the holes and cracks in the base layer, press the blade tightly with your index finger, and press the putty into the defect with force. Inside, it should be filled and filled thoroughly, and finally the putty around it should be scraped clean to minimize the traces of putty.
