A drywall sander is an integral tool of the drywall installation process that is used to sand and smooth the plastering compound. This is one of the toughest phases of hanging drywalls and can turn out to be messy and hazardous if not performed in the right way. You need to keep the following tips in mind in order to get the tool to work effectively for you.
Point 1: Many people, who do sanding using the drywall sander, do it after applying every coat of mud. This needs to be avoided. The sanding process must be done once which is at the end of applying the third coat of mud. Sanding after every coat can only add to the mess and make the process challenging and frustrating.
Point 2: Since a lot of fine dust rises in the air during drywall sanding, you have to ensure that you have safety goggles on to prevent the dust from entering your eye and causing irritation. It is also recommended that you use a mask with a ventilator while doing this work in order to prevent the dust from being inhaled. Inhaling this dust can lead to permanent damage to the lungs.
Point 3: For the drywall sander to work effectively and efficient, do not wet the sponge. Doing this is okay if you are sanding a small patch. However, if you are sanding a large area, use a dry sander.
Point 4: While using the sander, do not open the doors or windows for ventilation (though you may be tempted to do so because of the dust). Opening them will bring in air circulation but at the cost of raising the fine dust and causing more harm than good.
