Protecting limestone during installation

Limestone is a fabulous flooring material but, because it’s very porous, a little extra care is needed during installation.

Before fixing, always pre-seal your tiles.  This protects the surface from being marked and it eliminates ‘picture framing’ which is caused when grout bleeds into the edge of the limestone.


FILAPRW20-pre-treatment-limestonePre-grouting protector, FILAPRW200 is a great solution, as it protects without altering appearance, it’s really easy to apply – and it’s VOC-free too.  To apply:

  • Clean the surface to remove any dust.
  • Apply an even coat of FILAPRW200 using an airless spray pump, paintbrush or fleece pad.
  • Make sure you apply it right up to the edges!
  • Leave the surface to dry overnight, before fixing, and remove any excess grout with a sponge before it dries completely.

FILAPRW200 can also be used to pre-seal terracotta and quarry tiles.


Why is it important to pre-treat?


  • it protects surfaces from grout residues
  • it makes grouting easier
  • it makes cleaning after laying simple
  • it speeds up drying after initial washing and therefore also the subsequent treatment stages
