Restoring shutters

Restoring shutters
Painted wooden shutters weather relatively quickly and must therefore be renovated regularly. In the first step, this application example shows how to sand the shutters for this kind of renovation, to prepare them for painting. It describes how the slats (with slight or significant weathering) and the frame are sanded. The application example also provides recommendations for specific sanders and abrasives to use for the thorough wooden shutter restoration.

    Description

    The influences of weather expose shutters on building façades to high environmental loads and they therefore required relatively frequent repairs. The exact extent of the damage can vary significantly. Typically:

    • significant weathering and paint damage occurs on the side exposed to the weather and the side facing the sun
    • less significant weathering of the surfaces on the protected sides of the building

    But the renovation work is made more complicated by the shape of the shutters, and it is crucial to select the right sanding tool and abrasive to sand the painted surfaces in the narrow gaps between the slats.

    Tools/accessories

    The following tools and accessories are recommended for use in this application example:

    Procedure

    For slight weathering (LS 130 Duplex linear sander)

    • The DUPLEX LS 130 linear sander and slat sanding pad are ideal for sanding shutters that are not significantly weathered and have an intact coating without flaking. Alternatively, the fine sanding setting on the Rotex 125 can be used to restore shutters with minor surface weathering.

      • Attach the slat sanding pad to the linear sander
      • Set the speed to level 6.

      +
      The DUPLEX linear sander and slat sanding pad are ideal for sanding shutters with an intact coating.

      • Attach Granat P 80 abrasive sheets to the front area of the slat pad
      • Surface preparation

      Tip: By folding the abrasive sheet over the front edge of the slat pad, it is also possible to sand the reverse of the slat above.

      +
      Attach abrasive sheets to the front area of the slat pad

      • Fit the standard sanding pad on the linear sander
      • Set the speed to level 6.
      • Attach the Granat P 80 abrasive sheet
      • Sand the surface of the frame

      +
      Fit the standard sanding pad on the linear sander

    Procedure

    For significant weathering (RO 90)

    • In some cases, it is necessary to sand a significantly damaged paint layer on the frame right down to the wood. This is best done using the Festool ROTEX RO 90, as it can switch between coarse sanding, fine sanding and even sanding into the corners when using the Delta pad.

      Connect the extractor hose to the ROTEX.

      +
      In some cases, it is necessary to sand a significantly damaged paint layer right down to the wood.

      • Set the speed to 6
      • Coarse sanding setting

      +
      Set the speed to 6.

    • With the coarse sanding setting, the damaged paint is sanded off quickly using the Granat P60 sanding disc.

      +
      With the coarse sanding setting, the damaged paint is sanded off quickly.

    • The surface is then sanded again briefly with the same sanding disc in fine sanding mode and prepared for repainting.

      Tip: The Granat P 80-120 sanding discs can be used in fine sanding mode for regrinding, to further improve the surface quality.

      +
      The surface is then prepared for repainting.

    • To sand the slats, proceed as follows:

      • ROTEX in Delta setting
      • Attach the slat sanding pad

      +
      The slats are sanded.

      • Attach Granat P60 to the slat sanding pad
      • Set the speed to 6
      • Sand the slats until the desired surface quality for recoating is achieved. Work up through the grit levels if necessary

      +
      Sand the slats until the desired surface quality for recoating is achieved.
