Preparing Surfaces Before Sealing

Published 27 Mar 2019


All to often we see stone surfaces on busy sites that have been sealed, but not properly prepared before the sealing.





Resulting in sealed in boot prints, milling dust from cutting and grinding, and general dirt and grime.

Initial conditioning and cleaning before sealing is an important part of the protection process and ensures that the open pores of the stone are free from contaminants before filling with sealer.

The simple first step is quite commonly missed out and the consequences of this can lead to inadequate sealing resulting in staining and aftercare issues quite soon after installation.

To avoid these issues use LTP Grimex intensive cleaner.

Dilute 1:10 with water.  Wash down surfaces, rinse with water and then leave overnight to dry before sealing.

The result of this simple first step is deeper penetration of sealer, which will provide longer lasting protection………and of course…….no boot prints!
