What is the best tile and grout for travertine tiles?
To avoid discolouration on travertine, limestone or other light-coloured stone, the adhesive should be a white cement-based adhesive. Also, to avoid staining use a rapid setting adhesive. Ideal choices are BAL Rapidset Flexible Adhesive for walls and BAL PTB Flexible Adhesive (white) for floors. Lay tiles with 3-6mm solid bed onto floors. Do NOT spot fix, as this may result in shading. To avoid migration of materials in solution into the travertine stone, use a grout colour similar to that of the tiles. To avoid ”picture-framing’ effect on very porous stone, seal tiles with a suitable sealer. Also reduce the risk by using cement-based grouts containing a water-retaining agent. BAL Superflex Grout, BAL Wide Joint Grout, and BAL Superflex Wide Joint Grout are all suitable for use with natural stone. Alternatively, use a rapid-setting grout such as BAL Microcolour Grout or BAL Microcolour Wide Joint Grout.
