Preparing Surfaces Before Sealing

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!

Removing Grid Marks & Dust Residues From the Surface of Matt Porcelain


Super heated tiles that roll off of the production line are sprayed with water to cool them down before stacking. Sometimes a build up of dust and silica can remain on the underside of the tile; and when it is stacked on top of another tile; can cool to leave a hard to remove residue on the surface of the tile.
This can sometimes go un-noticed in larger factories because the tiles are collected and then packaged at the end of a production line by robots.

CLEANING:                   LTP POWER STRIPPER                                              1 & 5 ltr

LTP Powerstripper sold in 1 litres or 5 litresApply un-diluted LTP Power Stripper to the surface of the tiles and agitate immediately using a black course emulsifying pad.

Leave for 15 minutes. Add a little water and agitate again. Rinse with water and leave to dry.

If a slight residue remains once dry, repeat the above process.

Wherever possible clean the tiles prior to fixing. Cleaning solutions applied to vertical surfaces are not able to stay in place long enough to be as effective, making removal much slower. If cleaning a vertical surface start from the top and work down.
