Instructions: Sanding Timber Planks
Scratches, worn paint or an uneven floor - grounds, wood planks to grind, there are many. In this article, we explain to craftsmen how to sand their plank wood and make their wooden floor look like new.
A smooth floor surface is not a luxury but should be a must in every home. Unfortunately, there are small mishaps over the years, which cause unsightly scratches and worn paint layers. No problem, these little bumps & ldquo; can be easily compensated by sanding the wooden planks and then treated with suitable care products. Basically, only one grinder is needed for the work, its handling is not problematic. However, there are some things to consider in this work.
Tools and Preparation for Sanding Timber Planks
For sanding the wood floor, a home improvement needs the following tools and materials:
- Grinder: A roll grinder is used for the elemental sanding , This only does the rough work, for the fine grinding is a disc sander. The third device that craftsmen need is the belt sander available here. This is used for all corners and edges in the room.
- Sandpaper: Depending on the unevenness of their wood planks, sandpaper with different grain sizes is needed. The grain sizes range from coarse (16) to fine (120). Do-it-yourselfers should also be aware of how to attach the sanding paper when purchasing the sanding machine. This is either climbed, clamped or glued. The first function is best because you can quickly change the sandpaper when needed.
- Sealant: After sanding the boards, the seal follows. Depending on the type of wood, it is sealed with a suitable varnish, wax or oil.
- Respiratory protection: The sanding work produces very fine sanding dust, which should not get into the respiratory tract. For this reason, you should wear a respirator mask during grinding and disposal.
When the tool has been purchased, preparation for grinding begins. For this, do-it-yourselfers have to sink all screw and nail heads with a hammer and countersunk pin. This process is very important as a nail head can destroy the sanding paper and the grinding wheel.
Sanding the wood planks step by step
For the coarse and medium sanding as well as the first fine sanding, the roll grinder is used. Corners, edges and niches remain untreated - our belt sander is used for them. Depending on the condition of the wooden floor, several sanding cycles are required. Basically, home improvement should count on at least three passes. For an old plank floor, it can also be nine sanding cycles.
Do-it-yourselfers start with the rough grit: For a normally worn floor, grit size 40 is sufficient. For old, heavily worn floors or floors that have a thick surface Paint or paint layer, you should first grind with the grit 16, until you hit the wood. The grinding direction should run diagonally to the plank course. First she runs forward, then back on the same track. Pay attention to a smooth grinding motion for a perfect result as far as possible.
This is followed by the so-called center cut, in which the grinding marks of the previous grinding process are removed and the surface is refined. In this case, a sandpaper with a grain size of 60 is used. The sander is now maneuvered parallel to the floorboard.
Now there are corners and edges left that could not be reached with the large grinder. With an edge grinder of the same grain size you can machine these areas in circular movements. The polish between the surface and the edges should not have any unsightly transitions.
Finally, the polish grinding follows with a disc grinder and a 120 grit. This device can eliminate last bumps while refining the surface. The wooden planks are sanded again parallel to the board direction.
Oiling and growing the plank
After sanding, the sealing mentioned above follows with oil, wax or varnish. Especially recommended are products made of hard oil and wax, which are usually free from solvents. The purchased remedy must usually be applied twice so that it can penetrate deep into the pores of the wood. For the application of hard oil a mohair roll is used. Excess residues can be removed after 30 minutes with a felt pad. Dry times vary from product to product.
