Stripping hardened calcium stains from pavers is next to impossible. Conventional pressure washers, and chemicals will not get the job done.
National Sealing has a very effective solution; we can remove / strip the existing calcium deposits with a customized process that utilizes concentrated water pressure up to 40,000 PSI. This process also has a vacuum recovery system. Basically, the same effect that sand blasting would have – with water. This results in less mess, and a quieter and faster operation.
After the calcium stained surface was stripped, we then sealed the pavers.
