Why Seal and Sand Travertine

Travertine, Limestone and Natural Stone Pavers – Unlike concrete pavers, travertine and limestone pavers are natural. No color pigment has been used to achieve their color, so you will never have to worry about color loss from natural stone. However, rain and salt in the air and in salt water pools will deteriorate travertine and limestone pavers over time. By sealing the travertine, this will help prevent this from happening. Properly protected, these types of materials will outlive the home. Unprotected when exposed to these elements, expect them to last as long as man made products.

  • Equally as important as sealing travertine, limestone and other natural stones is keeping the sand material locked in the joints or gaps between each stone. This is assuming these stones were sand set and not mortar set. On sand set natural stone installations, the sand must be installed in the joints for several reasons. A few are:

  1. To create a cushion from one stone to the next to help minimize chipping,

  2. Achieve friction between each stone so that the stones move up and down as one and not independent of each other causing unevenness,

  3. The dirt in the joints prevents heavy rains and cleaning from washing out and eroding the sand bed beneath the pavers. This is the leading cause to unevenness between one stone to the next. We see it often where a client has a travertine pool deck full of uneven stones. The thing they all have in common is, the joints are empty from frequent pressure washing or neglect.

  4. 4. When the joints are empty, they are prone to fill up with airborne organic material that blows across the stones and begins to collect. This organic material turns the gaps between your stones in to a mold and vegetation breading ground.
