If there is a coat of paint or repair work, the grinding of the door frame counts Door frame for preliminary work.
Preparation before sanding
When sanding, there must be no old paint left on the frame. There are different techniques for removing the old paint or varnish layer. The old layer has to be removed carefully so as not to damage the wood.
Remove old paint by stripping it off
One option for removing an existing paint layer is pickling. The mordant replaces the old paint and varnish. Disadvantage of this method is the long-lasting, strong smell caused by the paint stripper.
Using a hot air blower to remove the paint
Coatings based on petroleum can be removed with a hot air blower. Partial heating with the hair dryer dissolves the paint. After loosening, the old layer is removed from the door with a spatula.
Identification of door hinges prevents mix-up
Before sanding, the door hinges must be removed from the frame. The identification of the individual hinges prevents a confusion of the individual parts when they are used again. Masking the hinged areas prevents them from being co-lacquered.
Masking protects against metal scratches
Some hinges or door locks can not be removed. For these models, it is important that they are taped clean before handling. This protects the metal parts from scratches and paint during sanding.
Sandpaper roughens the surface to
The use of sanders is preferable to sanding the sides with sandpaper. Coarse sandpaper can easily cause damage to the wood surface. Grinders work more precisely and can be borrowed at most specialty stores.
Pre-sanding prepares the wood
For good sanding results, pre-sanding with coarse 40-grit sandpaper is required. For large flat surfaces a plate or orbital sander is the right tool. A sanding block or triangular sander is ideal for machining corners.
Final finishing and fine sanding
The finishing and finishing touches round off the sanding result on wooden doors. For regrinding is paper with a 120 grit, for fine sanding a 200 grit. Small dust particles are wiped off with a cloth after sanding.
Careful work is everything
