Cleanest Process Explanation of Water Mill

Wet sanding is a great alternative to dry sanding when repairs have been made to damaged drywall or plaster, as well as in remodeling that occurs in or near lived-in areas of the home. In wet sanding, the sponge is damp enough to significantly reduce the amount of sanding dust that becomes airborne. For this reason, persons with allergies living through a remodel or repair may well appreciate this alternative technique. In high-use areas of the home such as kitchens or baths, wet sanding can significantly decrease the mess that normally accompanies drywall repair.

Wet sanding is a cleaner alternative to regular sanding of drywall mud from remodeling and repairs. Wet sanding requires a special sanding sponge that replaces the traditional drywall sanding screens and blocks. The sanding sponge is used barely damp and requires frequent rinsing and wringing during wet sanding.

When properly executed, wet sanding does not alter the number of coats of drywall mud required, but the process does take longer than dry block sanding. This is mostly due to the number of times the sponge must be rinsed and wrung out, and depending on the size of the area, the water may need to be changed as well. You can reasonably expect to sand about a 3-foot square (about one square meter) section before needing to rinse and wring your sponge.

After wet sanding a coat of mud, allow the area to dry for about an hour before continuing with a second coat of compound or before painting or priming if the final coat has been sanded. Combining wet sanding with traditional sanding is also an alternative for home repair projects. Perhaps the first coat can be sanded with a traditional screen or block sander to expedite the process, but wet sanding can also be applied in the final coat so clean up can be performed sooner. Though it takes more time to complete a project with wet sanding, it is definitely the cleanest process.mobile crushers:http://www.hxjq-crusher.com/10.html

Keeping a bucket of water next to you to rinse your sponge is recommended, but you must change the water when it becomes too murky to see into. You can use different grain sanding sponges for wet sanding, such as coarse or fine, depending on which coat of mud you are sanding. Wet sanding sponges are slightly larger than a typical kitchen sponge and are available at most large home improvement stores.

When wet sanding an area, work in circles with a steady amount of pressure. The sanding sponge should be only slightly damp -- if water is dripping from the sponge when you apply steady pressure during sanding, the sponge is too wet.
