How to Stucco over Painted Brick

Stucco is a material created by mixing an adhesive, lime and plain water. It is a soft wet paste initially but hardens into a very strong dense solid. It is applied to walls to protect them from seepage and give them a finished look. Stucco has been in use as a binder in the construction of buildings for centuries. It is used as an insulator and can also be used to create a textured surface on the wall for decoration purposes.

Applying stucco over a painted wall is not much different from applying it over a non-painted wall. The time cost of the project will increase by an hour or so depending on the size and conditions of the wall.

Instructions

  • 1

    Inspect the whole region where you want to apply stucco. Arrange a pressure water sprayer and use it to remove loose paint chips from the surface of the wall. Even if the paint is in smooth condition, use the sprayer to clean the wall.

    Rule of thumb is to hold the nozzle about a foot from the wall and set the pressure to about 1500 PSI.

    There is no need to remove all paint particles from the wall, but it is important to get rid of the loose paint from the wall. This cleaning will also moisture the wall and prevents it from draining water out of the fresh stucco layer.

    Use a concrete bonding agent to create an adhesive layer between the wall and to be applied stucco. You can either use a paint brush or a paint roller for this purpose. Ample time should be given to the adhesive agent to dry; a 24 hours break shall suffice.

    Apply about a quarter of an inch coat on the wall using a trowel. Move the trowel in semi circles to give it a smooth look. Give it about half an hour break and then scratch it with the help of a wire brush. Now once again give the wall a 24 hours break.

    Apply another ΒΌ inch coat of stucco over the wall with the trowel. This time around, use a metal trowel to give it a neat and finished look. Again give it a 24 hour break and after that apply a coat of paint with the help of paint sprayer.
