Wipe away the marker and use a rubbing stone to smooth the edges tile. Use a clean, damp cloth to wipe away the washable marker. The glass tile piece will be sharp and possibly a little rough, so take a rubbing stone, hold it at a 45 degree angle to the front of the tile, and rub it in a parallel motion over the edge to round and smooth it out. Rub the rubbing stone down the whole length of the edge. A rubbing stone can also be used to buff out any small irregularities in the break.
Turn on the saw and let it run for 15 seconds. Give the saw a chance to warm up and get going by turning it on and allowing the water to flow freely over the blade of the saw. Wait about 15 seconds before you begin cutting so you can be sure the saw is functioning properly and the water is flowing smoothly. Warning: If the water isn’t flowing, don’t cut with the saw! The friction could cause the glass to shatter and the blade could heat up and damage the saw.
Line up the cutting guide on the wet saw and the guidelines on the tile. The wet saw will have measuring or cutting guides that will lock the glass tile in place. Use the guide on the wet saw and match it up to the lines you drew on the tile with the washable marker, then slide the guide to lock the tile and keep it from moving. Align the saw carefully, because you won’t be able to undo a cut once you make it.
Push the tile through the saw and away from you. Feed the tile slowly through the saw with a light but consistent pressure as the blade cuts through it. Push with your hands on the edge of the glass away from the blade, keeping your movement continuous. Push the tile through the saw until it cuts all the way through for an even cut and a smoother edge.
Turn off the saw and wipe away the washable marker. When you have finished cutting your glass tile, use a clean cloth to wipe away the washable marker guidelines. Power down the saw and wait for the blade to stop spinning completely before you pick up or handle the saw. Wipe up and dust or glass pieces that may be on your saw or workstation.
