While it may initially seem simple to sponge paint brick, it can be all the more frustrating when the end result does not come out as planned. By following a few simple steps, you can ensure that your brickwork is sponge painted properly.

Step 1 - Prepare

One of the main reasons that a sponge paint design over brick can fail or turn out different than expected is the lack of preparation. Some people assume that the only preparation required is to gather the relevant materials. It is also essential that the brick surface you intend to paint is primed to accept it.

Cleaning the brick surface should be your first step and the manner in which you do this is dependent on the location of the brick you wish to paint. External walls can be cleaned with a pressure washer or with a scrubbing brush in accordance with accessibility.

Dusty internal brickwork can simply be vacuumed clean. However, this may not be sufficient for soot or the chalky white powder that can sometimes be found clinging to bricks. This sort of grime requires more effective cleaning, such as with a wire brush or with a scrubbing brush and soapy water.

Step 2 - Fix Holes

Once the bricks have been cleaned, you are in a position to fix any holes that could cause voids in the sponge paint design. Make use of a shrink-resistant spackle to fill any holes and cracks and allow it to dry completely before continuing.

Step 3 - Prime the Surface

It is advisable to use a 100% acrylic primer on the surface of the brick to make the subsequent paint easier to apply. Make sure the room is well ventilated and make use of a facemask so that you do not have to rush through the task. Be aware that it can take longer to apply primer to brick other materials due to the surface not being uniform. Allow it to dry thoroughly in accordance with the instructions before applying any paint.

Step 4 - Apply Paint

If you are using a basecoat, apply as many coats as is required to obtain the color required and allow each coat to dry completely. You are now in a position to apply your sponge paint and can begin by pouring a small amount of the paint chosen for the topcoat into the paint tray. Dip your sponge into the paint and tap it against a clean part of the tray to remove any excess. Start by lightly dabbing the sponge to a relatively hidden part of the brickwork and experiment with different sponges and amounts of pressure until you get the effect that you want. Ensure that you use enough pressure to take into account the deviations in the brick surface. Continue with the rest of the brickwork until you have completed your design.
