Pool Plastering - What You Need To Know About Plastering Your Pool

The Procedure for Plastering a Pool

Do you want to see how a regular pool plastering job is done? While each project is as unique as the customer and their pool, there are some common threads that run through all of our pool plastering and pool replastering projects. Here’s a quick breakdown of the plastering procedure that our skilled and professional pool contractors provide:

Step 1: Select a Plastering Color

Clear and unambiguous communication is the foundation of any successful pool plastering operation. We work closely with each client to develop a project cost and timeline that outlines all of the work that needs to be done to replace pool plaster.

Our Houston pool plastering crew will demonstrate the several pool plastering color options available for your pool. We’ll show you how to choose the right color for your pool, whether waterline tiles should be added, how your color choice looks at different water depths, and more! Our goal is to make you understand the procedure and feel at ease with our knowledgeable staff.

We’re thrilled to now be able to provide fully digital plastering catalogs complete with color swatches and more. You can look over our plastering color selections online here: Colors for Pool Plastering

Step 2: Draining the Pool

Our staff will arrive at your property and get to work once we’ve decided on a course of action for your pool plastering project. The first stage in a professional pool plastering job is to completely drain the pool with our submersible pumps. This makes it possible to drain the water fast and effectively. The submersible pump is normally placed in the shallow end and left running until the water is mostly drained, after which our team will come in the next day to finish the draining!

Step 3: Relieve Hydrostatic Pressure

The removal of hydrostatic pressure from beneath your pool is an important aspect of the replastering process. This will prevent the pool from “popping up” during the plastering process. There is nothing holding the pool down in its place now that the water is gone, which could result in your entire pool springing up! This is why removing the hydrostatic pressure is so important.

Step 4: Plaster Prep

After the hydrostatic pressure under the pool has been relieved, the pool must be prepared for plastering by undercutting all waterline tiles as well as any pool fixtures and features such as lighting, jets, returns, and the main drain. Undercutting allows us to start working in the plaster right away.

Step 5: Examine For Cracks & Hollows

After the pool has been completely drained and prepared, we will thoroughly inspect the swimming pool walls for any cracks, hollows, or other issues that could compromise the resurfacing job’s longevity. 

When calcium nodules mature, they form hollows. They produce a hollow space beneath the plaster surface of the pool, which eventually causes degradation, bubbles, and delamination. 

These “hollows” or voids can be generated by a variety of factors, and they are common in all pools. We normally cover up to 15% of these hollows, which is usually adequate to get most pools replastered on schedule. 

We start washing the pool walls with muriatic acid once the hallows have been pounded out, cracks have been handled, and the pool has been thoroughly inspected (If needed).

Step 6: Acid Wash

Washing the pool walls with muriatic acid removes a thin layer of the surface and aids in the removal of tenacious stains, calcium deposits, and other debris that may have accumulated on the previous plastering finish applied to your pool. It also aids in roughening the surface, allowing the bonding elements in step 7 to better bind the old and new finishes.

Step 7: Bond-Kote

After that, a specialized bonding material should be applied to ensure good adhesion between the existing and new pool plastering finishes. Bond-Kote is a one-part resin, one-part bonding cement acrylic modified cement and sand mixture. 

Following the mixing of these two parts, they are rolled or sprayed onto the pool wall and flooring, allowing the old and new to connect.

Step 9: Scrub The Entire Surface

This only smooths out any uneven areas that may have developed during the application process. It also allows the roughness to be smoothed away, making new pool plaster more comfortable to walk on!

Step 10: Installing New Tile & Coping

If you choose to have new waterline tiles or coping/deck installed, we will work on these items while replastering your pool. Each of these has its own set of procedures! We’ll go on to the final inspection once these, as well as the plaster, have been placed. Phew!

Step 11: Final Inspection

A final inspection will be performed before filling your pool with water to confirm that the plastering has been properly applied. Prior to refilling, the staff will take care of any necessary fixes or upgrades. This method of measuring twice and cutting once eliminates the possibility of any problems or errors.
