Painting natural wood doors white

    Description

    Problems often occur when painting doors. Streaking or adhesion problems can occur. To achieve a perfect result when refurbishing and painting a door, it is important to use the right tools and suitable paints.

    List of materials and tools:

    • Synthetic resin filler or fine filler
    • Dust cloth
    • Paint bucket (large and small)
    • Masking material and adhesive tape (e.g. gold tape)
    • Painting tools: paint roller, leaf brush, ring brush
    • Wooden wedge for door
    • Undercoat (alkyd resin/solvent-based)
    • Main coat (alkyd resin/solvent-based)
    • Working blocks
    • Cleaning material

    Preparing/adjusting

    • Set up your workstation

      Prepare a clean and dust-free workplace. We recommend a suitable system consisting of a vacuum cleaner, sander and suitable Grit Abrasives.

    Procedure

    • Check existing door

      The first step is to check the door. Is there any visible damage or is the door rubbing against the floor? If there are any problems, we recommend adjusting the door to the floor height. The floor height often changes during renovations - whether due to underfloor heating or a new floor covering. We therefore measure the new height at the door hinges and shorten the door leaf to the right size using the Plunge Cut Track Saw and Guide Rail Saw.

    • Make the door accessible and dismantle the fittings

      We then check the fit of the door. By hanging the door leaf, we can determine whether it is rubbing anywhere or if it is jamming when opening and closing. If this is the case, the door must be readjusted. For the subsequent painting, we unhinge the door again and remove the fittings with the ratchet set. Then we are ready for the next step.

      +
    • Sanding the door leaf - surface

      Now we sand the door. We use a Random Orbital Sander - ideally the ETSC 2 150 - to achieve an even and high-quality surface finish. We recommend using Granat universal sandpaper with a grit size of P180. This ensures that both sides of the door leaf are sanded evenly. Thanks to the integrated light, any unevenness or damage to the surface of the door can be detected directly and marked with a Pin if necessary.

      +
    • Sanding the seams and edges

      An orbital sander is recommended for sanding the rebates on the door leaf. Here, for example, an RTSC 400 can also be used with a grit size of P180. This allows the rebates to be sanded better thanks to its perfect fit. Hard-to-reach areas are reworked with a hand sander. After sanding, dust should be removed from the door. A suitable vacuum cleaner with a Suction Brush is suitable for this.

      +
    • Flaws and scratches

      When sanding the door with the ETSC 2 and its integrated light, imperfections and scratches become apparent. The surface is checked again with the small KALC Work Lamp and damaged areas are marked with a pencil. The damage is then filled with a Japanese spatula and synthetic resin or fine filler to achieve the smoothest possible surface. Tip: When applying the filler, make sure that it is removed cleanly to achieve an even result.

      +
    • Preparing the door frame

      While the filler is drying on the door leaf, the door frame is also prepared. The procedure is largely the same as for the door leaf. An orbital sander such as the RTSC 400 is recommended for the frame, as it has many edges and rebates. Here, too, we use Granat abrasive paper with P180 grit. Finishes and details can then be reworked with the Granat hand sander. The remaining dust is removed with the Suction Brush and the CTMC Midi. Damaged areas must also be repaired with filler and Japanese filler.

      +
    • Final sanding of door leaf and frame

      The damaged areas on the door leaf and door frame filled in steps 5 and 6 are sanded again after drying. Here too, we recommend using an eccentric disc sander with Granat paper abrasive P180 to create a flat surface and remove any unevenness created during Scraper blade application. After sanding, the door must be Dust extraction again. Check the surface again with the KALC and touch up any other damaged areas. And repeat the work steps. This work step is also carried out on the door frame.

      +
    • Preparing for painting

      Before painting, the surfaces are cleaned again with a dust-binding cloth. In places that are difficult to access, mask off with gold tape to protect the wall, for example. The painting tools and the undercoat to be used are prepared and can be placed on the CTMC Midi at a comfortable working height. we recommend covering the Dust extraction unit with a newspaper for protection and storing the tools and paint in a bucket to avoid unnecessary contamination.

    • Painting - undercoat door frame

      The lacquer recommended and used here is an alkyd resin-based, solvent-based lacquer system. This allows us to completely coat the door with just two coats. With water-based systems, an additional insulating primer would have to be applied. The primer is applied evenly with a paint roller. A brush can also be used in hard-to-reach areas. When applying, ensure an even coating to avoid streaking and dripping.

      +
    • Painting - undercoat door leaf

      In the next step, the door leaf is also painted with the undercoat. We start at the rear rebate and can then hang the door to paint the remaining rebates with a brush. The surfaces of the door leaf are then treated with the undercoat. When doing so, make sure to roll the surface linearly from top to bottom in order to achieve an even application. To keep the door leaf stable during painting, we recommend using a wooden wedge - this ensures that the door leaf stands securely and does not wobble.

      +
    • Drying time

      The door must first dry after applying the undercoat. The brush can be placed in a glass of water so that it does not harden and can be reused. The paint roller must be disposed of.

      +
    • Intermediate sanding

      Once the undercoat has dried, it is advisable to check the door again for damage. If further damaged areas are discovered, these can be repaired again with fine filler. Cracks or similar areas can also be repaired with acrylic. Once the repaired areas have dried, the surfaces and any remaining filler can be sanded down again. For large areas, we recommend using a Random Orbital Sander, ideally with P400 grit Granat sandpaper. Details and hard-to-reach areas can be sanded with a sanding sponge. Do not use coarser grits, otherwise the undercoat will be removed too much. Finally, Dust extraction and clean the surface with a dust cloth.

      +
    • Varnishing

      For the second coat of varnish, we use a silk gloss varnish, also a synthetic resin and solvent-based system. The door is unhinged again for painting and we start with the frame. Then, as before, the inner rebate of the door leaf is painted before the door is re-hung. Now the rest of the rebate and finally the surfaces can be painted. Thanks to the solvent-based paint, there is enough time to spread the paint evenly with the roller. After about 10-15 minutes, the surface should be checked again to ensure that the lacquer has been applied evenly; minor touch-ups can be made if necessary.

      +
    • After drying, the fittings are reattached to the door. The ratchet set can be used again for this. The door is then finished and you can move on to the next project.
