Laying a natural stone flagstone floor

Posted on October 4, 2011

Flagstone flooring lends a touch of class wherever it is. No matter where you choose to install your flagstone, we have the stone to fit in with your need. When laid properly flagstone floors provide durable beauty for years to come.

1. Start with the surface that will be under your floor. On new construction, a subfloor of concrete may be poured, providing a level surface. On a bathroom floor, the installation of a water-resistant backer board could be necessary. On a timber floor it is advisable to ensure that the floor is solid and does not flex when it takes weight, It would also be prudent to consider a decoupling mat, for both timber floors and over newly laid concrete slabs particularly if they incorporate a wet underfloor heating system. which will compensate for any movement between the substrate and the flagstones.

2. Figure out the total amount of stone tiles you will need by measuring the length and width of the floor and adding 15 percent more to allow for cutting and fitting pieces around the edges. Purchase adhesive and grout made specifically for the natural stone or flagstone flooring you choose. Because different stone retains moisture at various rates and because the surfaces vary from rough with holes to glass smooth, it is very important to choose the correct adhesives and grouts. We are very happy to offer advice about which products should be used.

3. Begin laying square tiles in the middle of your room and working outwards. Use straight chalk or pencil ines on the subfloor as guides. However, if your walls are not perfectly straight, consider which part of your floor needs a straight edge and begin tiling there. Keep in mind that the last tiles will be uneven so plan to install them in a place not frequently seen. See our laying patterns for flagstones.

4. Flagstone floors and other porous surfaces always require the application of a sealant. Because tiny holes exist in natural stone, they can absorb stains, making it difficult to clean. Sealant provides an invisible water-resistant protective coating that repels dirt and stains.
