Protecting encaustic tiles - before & after grouting

Protecting encaustic tiles - before & after grouting

Encaustic tiles have a timeless appeal and they’re available in so many different styles – from modern geometrics to traditional curlicues. Authentic designs are made by hand, using traditional frames and moulds; a mix of natural marble powder, cement and coloured pigments creates the surface pattern and the tile’s generally have a sand and cement backing. As a result, they’re porous and can easily become stained, so they will need to be sealed before and after grouting.


Before sealing, we recommend a thorough clean with LTP Grimex, using a 1:10 dilution. This applies to both newly laid and renovation projects. It’s also important not to use an acid-based detergent; encaustic tiles are sensitive to acid, which can etch the surface and damage the grout joint – and the sealer once the tile has been protected.


When it comes to sealing there are various options available, depending on the look that you want to achieve. Impregnating sealers LTP Mattstone or the water-based equivalent LTP Mattstone H20 are popular, as they protect the tile without altering the appearance. Depending on the type of encaustic tile being used, up to three or four light coats of sealer might be needed. Always test on an inconspicuous area first and buff off any excess.

LTP Colour Intensifier is also popular, as it enhances colour and will bring out the different tones within the tile. Like Mattstone, it’s also an impregnator, so it will allow the tile to breathe. For ongoing maintenance, we recommend LTP Waxwash.

A correctly sealed and maintained encaustic floor should last three to four years before resealing is needed.  For more information, please follow the link: Encaustic Tiles guide
