LTP Ferrex is an acid based stone cleaner which removes rust outbreaks from ferrous hard stones. For use on sandstone granite and slate. Suitable for interior &
Natural stones often contain traces of Iron, which may oxidise when they come into contact with moisture either from rain or cleaning. It can also occur when stone comes into contact with certain acid-based cleaners that contain ingredients that can accelerate the oxidisation process. This would include some brick acids and cement removers. The result of this oxidation is that the stone develops rust and discolouration. LTP Ferrex is specifically formulated to help remove these blemishes.

Suitable for use on acid resistant natural stones including granites and slates. Not suitable for highly polished natural stone as the effect is limited or limestone and marble.
Directions for use
Preparation:
Ensure surface to be treated is completely free from loose dust and dirt before application.
Application:
SHAKE WELL BEFORE USE.
Test on a small area before general application. Apply the solution to the surface and spread out evenly.
For external applications garden sprayers can be used.
For severe cases surfaces should be agitated using a short haired scrubbing brush or black emulsifying pad.
After 3 – 6 hours, rinse with plenty of clean water.
If traces remain after a couple of days repeat the process.
After treatment the surface should be protected from water.
Further treatment:
Sealing with an impregnating sealer such as LTP External Stone Sealer or LTP Mattstone H20 will render the surface resistant to water penetration, greatly reducing the possibility of rust discolouration from returning.
