Before you start stuccoing your fireplace, it’s crucial to prepare the surface to ensure the stucco adheres correctly. Below are the steps you need to follow to prepare your fireplace for the stucco application.

Cleaning The Fireplace To Remove Any Dirt Or Debris

The first step in preparing your fireplace for stucco is to remove any dirt, debris, or loose material from the surface. Here’s how:

  • Use a stiff-bristled brush to scrub the fireplace surface, making sure to remove all loose material, dirt, and debris.

Applying A Coat Of Bonding Agent To The Surface Of The Fireplace

After cleaning the surface, you need to apply a coat of bonding agent to the fireplace surface. Doing so will help the stucco adhere to the surface properly. Here’s how:

  • Cover the floor around the fireplace to protect it from any dripping bonding agent.
  • Mix the bonding agent solution according to the manufacturer’s instructions.
