A brick privacy screen is considered to be very durable. However, this small structure is also subject to a certain amount of aging due to the effects of the weather. Damage to the plaster, joints or even cracks in the masonry occurs. With a little manual skill and our instructions, you can repair the garden wall yourself professionally and inexpensively.
How can I repair a garden wall myself?
To repair a garden wall, first remove loose plaster and clean the wall thoroughly. Fill out any unevenness, fill cracks, apply adhesive primer and re-plaster the wall. Finally, paint the wall with exterior paint. For natural stone walls, replace missing stones and fill the joints with lime mortar.
The individual work steps:
- Inspect the wall and eliminate defective areas.
- Fill masonry and cracks with filler.
- Apply primer.
- Freshly plastered.
- Beautify the wall with a coat of paint.
Since the materials used always have to dry thoroughly, you should choose a few days for the work on which good weather is forecast.
Determine damage and remove loose plaster
If the facade is crumbling or the material in the joints is coming loose, you must first remove the damaged areas. Then clean the garden wall thoroughly with the high-pressure cleaner.
Spackling masonry
All uneven areas must now be leveled out. Depending on the existing surface, use lime-cement plaster or external adhesive plaster.
Filling cracks
Surface cracks can be covered or filled with materials available at hardware stores.
Apply primer
The facade of an older garden wall often offers inadequate adhesion for the new plaster. That's why you should paint the entire area with deep primer.
Re-plastering
The plaster of a garden wall consists of at least two layers. First, apply the base coat. This is followed by a smooth or structured finishing plaster, depending on personal taste.
Painting the garden wall
Finally, paint the repaired garden wall with an exterior paint.
Damage to the natural stone wall
Wall plants and lichens should not be removed as they protect the masonry from rain, frost and temperature fluctuations. However, you should immediately pull out any trees that germinate in the joints and cracks, as their strong roots can destroy the natural stone wall.
If individual stones are missing, you can reinsert them using suitable stones and lime mortar. Do not seal the joints, which may be two to four centimeters deep.
Tip
So that rain and frost do not cause damage, the garden wall should have a cover. This should have a slight slope so that water drains away easily, as well as a drip edge that protrudes at least five centimeters above the masonry. Brick or concrete slabs, natural stones, metal sheets or roof tiles are suitable as a cover.
