Encaustic cement tiles can withstand conditions outdoors in locations that are adequately protected, for example on a covered patio, or on a terrace in a Mediterranean climate. Nevertheless, as these tiles are slightly porous, slight cracks or chips may occur in the event of frost or if they are clogged with moisture.

To help diminish these frost-related issues, we would advise the following:

1. Lay the tiles on an impermeable or completely waterproofed concrete screed.
2. Lay the tiles with a double spread of adhesive, otherwise the formation of pockets of water under the tiles could loosen or crack them in the event of frost.
3. Use an adhesive suitable for outdoor use.
4. The joints must be well made and maintained to avoid the infiltration of water.
5. A sufficient gradient is required to drain water quickly and prevent puddles.
6. In addition to good drainage, we recommend that you re-seal the tiles regularly (every 12-18 months).

NB: When laid outdoors, the some of the pigments may be subject to fading due to sunlight or acid rain. However, the level of inconvenience this causes depends on your individual tolerance and taste. Some people particularly like the ‘mellowed’ or ‘aged’ affect that this produces.
