Perfect deck is a dream for everyone. But just like a pet it also require care and maintenance. There are variety of sanders available in market that are used to sand a deck. One can use standard orbital sander operated by hand or any other commercial sanders. You can do deck sanding with either of these sanders and get the good aftereffect if used appropriately. Its all depends on the way how you have used it. Patience is required while sanding, specially in the case of a large deck. If you are using a hand sander then it may require several days of work.
We are using very advanced sander having a unique soft brush. Its a German sander from Germany Engineered Terrassen-Blitz. This powerful machine removes all previous coatings, dirt, grey and moss without using water, high pressure or chemicals. It removes most stubborn layers even in narrow edges and corners which is not feasible with any other sander. Unlike conventional belt sanders with abrasive belts, there is no loss of the timber profile. Most importantly, the built-in vacuum cleaner sucks up dust, dirt and allergens so there is no health hazard. The most important feature of this machine is, "It didn't sand the nail which no other sander can do".
