Repairing Plaster in a Pool: A Step-by-Step Guide

For many homeowners, pool plaster can often be one of the most difficult jobs to tackle. Fortunately, this task is much easier when you know how to properly go about it. In this article, we will explore how to repair plaster in a pool, whether it is empty or full.

Step 1: Preparation

Before you begin the repair process, there are several important steps you need to take in order to prepare for the job. First, you will need to empty the pool for plaster repairs if it is full. If not already done, take care to completely drain the water from the pool. Make sure to shut off all electricity sources to the pool, as this is essential for a safe project. Additionally, you should gather the right supplies and materials in order to begin repairs. This includes: an abrasive paper, a pool patch adhesive, pool plaster mix, sealants, an acid wash solvent, and a finishing trowel.

Step 2: Removing Damaged Plaster

After the pool is properly drained and prepared, it is time to start removing the damaged plaster. Using an abrasive paper, or grinding wheel, remove the damaged areas of plaster. Be sure to wear protective googles and a dust mask for this step. Continue sanding until the entire damaged area is removed, going slightly past the chipping or worn area in preparation for the new plaster. Thoroughly clean the surface with a chlorine solution, sweeping away any remaining dust.

Step 3: Applying the Pool Patch Adhesive

Once the surface is prepped, you can apply the pool patch adhesive. Use a trowel to spread this adhesive into the chipped area, creating a thick and evenly distributed layer so the plaster can properly adhere. After the adhesive is applied and dried, take a damp cloth to clean away any excess, leaving the surface ready for the new plaster.

Step 4: Applying the Pool Plaster

Pool plaster is a dense and durable material that can cover the patch adhesive and fill any remaining gaps or imperfections. Mix the plaster according to the manufacturer’s instructions and apply the material over the patch adhesive. Use a trowel to create an even and uniform surface. Make sure to use the trowel’s edge to shape the plaster along the walls and floor of the pool.

Step 5: Finishing

Once the plaster is firmly set, use an acid wash solvent to clean any excess or debris that may still be present. Finish with a fine sanding, paying extra attention to the surface of the finished work. Begin with a coarse grit paper, and then move to a finer grit paper.
