1) Prepare the Job Surface:
• All prep work should be completed prior to measuring/templating. This includes the installation of all backer boards, sanding/filling of all surfaces and adjacent areas, locating sink cutouts, trial fitting of any appliances or fixtures, and verification of the location of all plumbing or electrical sources/drains/devices. Once we receive your layout and begin production, any changes will be billed accordingly.

2) Measure / Template:
• Square or Rectangular shapes are easy enough to accommodate with length and width dimensions. Care should be taken to compare diagonal measurements to see if your layout is “out of square”.
• More complex layouts warrant the use of a template. Kraft paper works well, can be laid out over the entire surface and pieced together with tape if necessary. Cut out any plumbing or electrical openings, so the rock tile can be laid around them. Also, label the edges of the template as to what we’re up against and how much margin you need to the stone.
• Be sure to mark your template with Up, Down, Left and Right and especially Front (or Face) and Back!
• Please Measure/Template your layout tight to the edges, and we’ll allow for margins and laps.
• For plumbing, electrical and other openings, please locate them by the center of the hole. This combined with the diameter, or length and width will suffice. Please provide the actual size of the drain hole, electrical box or vent hole and the margin desired around them.
• When providing measurements for a layout with openings, please pull all dimensions from a common base line.
• Select and Indicate a base line for both directions on the template and the surface to be tiled. This will allow us to locate any changes on the plan that may arise between measurement of the job and shipping the project. It will also help to start your installation with the proper placement and orientation.
• Call with any questions or items of concern prior to sending your template into the shop for fabrication!

4) Peel the Tape:
• Begin at the starting point of your layout and hold the tape tight to the tiled surface as you peel it back on itself. Do not lift straight away from the tiled surface or you may pull the tiles loose from their placement. Should this occur, “back butter” the tiles and replace them in their original position. Work gently and steadily through the job in the same order that the tile sections were placed.
• Any excess mortar can be cleaned from the grout joints at this time. You will note that the mortar is still green at the surface when the tape is peeled. This is because air has been denied access to the mortar by the Tile Tape, and the Thin-Set actually cures from the bottom up. Experiment with mortar removal tools – we’ve found useful value in everything from small blades, nut picks and pointing trowels to vegetable brushes and wire brushes, combined with either compressed air or a shop vac. Use caution with the air though, it can really blow things apart if you’re not careful!
• It’s Break Time! Allow your Thin-Set to cure in accordance with manufacturers instructions – usually at least 24 hours.

5) Grout:
• Mix and apply sanded grout in accordance with the manufacturers’ instructions and allow to cure completely.

6) Acid Wash:
• Most of the rock we use is quite porous and will require an acid wash prior to sealing.  Without it, the grout will fill all the micro-pores of the stone, stain the surface, and drastically mute the colors of the tile.  A 10% solution of Muriatic Acid/Water and a stiff bristle brush will lift any grout residue from the pores of the tile.  Then rinse thoroughly and allow to dry completely.

7) Seal:
• Seal with a penetrating sealer and/or color enhancer. Again, this material is quite porous and may require several coats. Apply in accordance with the manufacturers instructions and allow to dry completely before use. The final appearance will be greatly affected by your choice of a Matte, Semi-Gloss, or Gloss Finish. Also bear in mind that the higher the gloss, the lower the coefficient of friction will be; an especially important consideration in flooring applications.

8) Admire and Enjoy!
• At this point, it’s time to admire the beauty of another completed Idaho Rock Works project! We’d truly appreciate any comments you have on our product and the installation process – both positive and negative! Any tips for improving the system will be appreciated by those who follow in your foot steps. If you have the ability to take photos and send them to us, we’ll include your project in our website photo gallery! Before and after photos are ideal.
• We know you have a myriad of choices when it comes to building materials. Thank you so much for choosing Idaho Rock Works for your tile project! 

3) Lay the Tile:
• Locate the layout guide from your package and orient yourself to the starting point of your project. 
• Mix and Spread “Thin-Set Mortar” with a 1/4” x 1/4” square notched trowel in accordance with the manufacturers instructions. Do not get ahead of yourself by spreading too much at a time.
• Invert the first section and moisten the tile backs with a sponge. (That’s right, the tape is on the face, or top of the tiles! Do not remove the tiles from the tape yet!) Then align the edge of the tile tape with your layout, and/or align the base lines indicated on the tiles with the base lines from your project. The tape edge should match the edge of your measured area or template. Firmly press each tile into place, but try to avoid squishing the thin-set clear up to the back of the tape. If this should occur, do not worry about it yet.
• Moisten the back of the next section and mate the tape edges to the first section as exactly as possible. If for any reason you need to adjust individual stones, you can easily cut the tile tape with a utility knife.
• Continue placing tile sections, being sure to moisten the backs and to press each tile into place so that they are completely bedded in the mortar.
• If any of the tiles need to be trimmed, you can use tile nippers or a diamond blade saw or grinder. Assuming that we started with an accurate template, this should never be necessary!
• It’s Break Time! Allow 1-2 hours of undisturbed curing time before attempting to remove the Tile-Tape from your project. Take note of the curing conditions on your jobsite – cool, moist conditions will require longer cure times.
