What is a Scratch Coat?

Uncategorized |

When renovating an existing concrete pool, the scratch coat can be an important preparatory step that helps create a smooth, even surface for your new pool finish.

A scratch coat is a thin layer of cement-based material applied to the existing concrete pool shell. This layer is deliberately roughened or ‘scratched’ to create a potential bonding surface for the final render. Not all pool renovations require a scratch coat, but in cases of significant surface irregularities, it can be an effective solution.

The process helps to:

Level out minor imperfections in the existing concrete shell
Seal minor surface inconsistencies
Create a more uniform base for the final finish

At Rainbow Quartz, we assess each pool we renovate to determine whether a scratch coat is necessary. Our locally manufactured products and experience allow us to provide tailored solutions that address the specific needs of your pool renovation.

Pool owners should work with professional pool builders who can evaluate the condition of the existing pool shell and recommend the most appropriate preparation method. Some pools may require minimal preparation, while others might benefit from a more comprehensive approach.

When considering a renovation, it’s important to understand the various options available and choose the method that will deliver the best long-term results for your pool.

Hopefully that helps to give you a bit more understanding of pool renovation techniques.
