Repairing a shelf without using a dowel

In Home & Repair by Jinitto AdminLeave a Comment

Who has not been confronted with a shelf whose ankles have failed under the weight? Same for installing curtain rods on surfaces that have already been drilled several times. The good filling paste should make it possible to remedy these problems if when it dries it is strong enough to support new screws directly on it, and thus without using a pin.

Necessary material

  • Measuring cups
  • A bowl
  • Filler knife
  • Screwdriver
  • Dusting brush or vacuum cleaner
  • Sanding pad
  • A thin abrasive
  • A wooden tenon

Steps

1. Prepare and clean the wall

The fixing system of the shelf is usually hidden between the wall and the shelf, and it may wear under the weight of heavy objects put on the shelve. Moreover, the coating of the wall proved to be too crumbly and the anchors did not hold, making the shelf unusable.

Remove the fixation system from the shelf, retrieve the screws and remove the dowels completely.

Then, carefully clean the wall with a brush or vacuum cleaner. The latter makes it possible to better clean the holes from the potential residues of the old, too crumbly coating.

2. Prepare and apply the filler coating

Prepare the filling using 2 cups of water per 5 cups of powder. Pour the powder over the water and mix thoroughly to obtain a thick paste. Once ready, the coating can be used within 40 minutes (a little less in high heat).

Generously apply the prepared plaster and thoroughly penetrate it into the bottom of the recessed holes. The use of a small piece of wood like school pencil or tenon of carpentry fills this role perfectly. Smoothen the surface by spreading out the paste along the borders of the whole. It is better to put more paste than less. While drying it will shrink, so don’t worry you can top it up.

Wait until the coating dries then start sanding the surface. Remove any excess until you get a flat surface. If you have used paste of the same color as the wall then you won’t need to repaint. Otherwise, repaint with the same color as the wall.

3. Hang the shelve

Then reposition the shelf on the new marks to make sure all measurements are correct. Once you are happy with that then drill the necessary holes of the same diameter as the screws and on the marks you made. The hardness and the strength of the product you used should make it possible to dispense with the use of pins. If the shelve is outdoor make sure the filler coating is waterproof.
