Bead Blasting – An Effective Tile Cleaning Method
No matter how clean you think your swimming pool is; calcium, lime, and hard-water deposits will develop along the water level on the tiles. While it is possible to scrub these deposits off manually, we have the best results when using the bead blast technique. If the stains are not properly cleaned off the pool tiles, a rough surface could develop and become an inviting surface for algae.
This is a process that involves spherical particles being forced against the tile surface of the pool at a low speed using compressed air at a rate of 65 psi.
It is similar to sandblasting in that the process is a surface treatment designed to provide an even and smooth finish. There are a variety of materials used in bead blasting such as garnet and walnut shells, which produce their own unique surface finish. However, glass bead blasting is the most popular choice for standard plaster backyard pools.
While you could attempt DIY bead blasting, it is best to allow a professional, such as Swimming Pool Butler to handle the job. It can be a difficult process, unless you know the equipment and if you apply too much pressure, there is a high risk of etching.
The glass beads used in the procedure are made from soda lime type glass and are lead free. They have been formed into spherical shapes and are also free from silica. One of the main advantages of using glass beads is that they do not scratch the tiles and produce a glossy finish that will not occur with other types of blasting bead. The spherical shape ensures that the beads do not have a cutting action, which means no altering the finish of your pool’s tile. As an added bonus, glass beading is eco-friendly and does not involve the use of chemicals.
There is also the option of soda blasting, which is a synthetic form of cleaning. Sodium bicarbonate is used in a high pressure solution that uses incredible force to get the job done. In some cases, the pressure is as high as 1,000 psi. While this helps achieve a great clean, it also increases the likelihood of damage. Soda blasting also involves the use of chemicals, so landscape plants surrounding the pool will die if in contact with the blasting dust deposits. It is also much more costly than going with glass blasting.
Another alternative we use to glass bead blasting is to apply some elbow grease and use a brush or pumice stone. While you can produce great results using this method, it is not a feasible approach to removing large deposits of calcium or lime. As a professional pool service firm, we are sure to vacuum up all debris left behind by the glass bead blasting, which will remove calcium fragments and glass beads from the pool.
