How to Fix Up an Ugly Block Wall

Spray and clean exterior walls using a pressure washer or a garden hose with a pressure nozzle. Remove remaining paint with a wire brush or a paint scraper. Allow the wall to dry a minimum or 24 hours if it is in direct sunlight, drying time will be longer for a shaded wall.

Clean interior walls with a wire brush or scraper to remove loose paint, and scrub clean with a stiff brush and mild detergent and water solution. Allow interior walls to dry at least 24 hours or longer depending on the humidity in the room.

Fill small cracks with concrete filler. Place the concrete filler tube into a caulking gun and run a seam of filler into the crack. Wipe off excess filler with a damp cloth and allow the filler to dry according to directions.

Paint the wall with primer using a paint roller. Select an acrylic primer designed for block walls. The primer will fill in holes and ensure the final paint will adhere to the wall.

Select the appropriate exterior or interior acrylic paint for the final coat of paint. Trace several lines, freehand style, to represent a trailing vine on the wall. Cut templates of various sizes of leaves and add along the vine.

Choose three or more different shades of green paint and paint the vines and leaves. Create a realistic leaf by adding veins inside the leaves.
