Applying the Kneaded Mixture

Applying the benzoyl peroxide mixture to damaged bricks requires careful and precise application. It is crucial to achieve a smooth and even layer to ensure proper bonding and a seamless repair.

Prepare the surface:Before applying the mixture, clean the damaged brick surface thoroughly. Remove any loose debris, dirt, or dust. Use a wire brush or a scraper to remove any loose mortar or paint.
Apply the mixture:Use a putty knife or a trowel to apply the kneaded benzoyl peroxide mixture to the damaged area. Apply a thin, even layer, ensuring that the mixture fills all the gaps and cracks.
Smooth the surface:Use a damp sponge or a smooth trowel to smooth out the applied mixture. Ensure that the surface is level and flush with the surrounding brickwork.
Clean up:Clean any excess mixture from the surrounding brickwork with a damp cloth.

Curing and Drying the Repaired Brickwork

Curing and drying the repaired brickwork is an important step to ensure proper bonding and a durable repair. The process involves controlling the environment to allow the benzoyl peroxide to react and harden.

Protect from moisture:Keep the repaired area dry during the curing process. Avoid exposing it to rain or excessive humidity. A tarp or plastic sheeting can be used to protect the area.
Control temperature:Maintain a consistent temperature during the curing process. Avoid extreme temperature fluctuations, as this can affect the curing process.
Allow for drying:The drying time will depend on the thickness of the applied mixture, the ambient temperature, and humidity levels. Allow sufficient time for the mixture to fully cure and harden.
