There are many situations in which you will want to bullnose travertine. If you are installing a new countertop, you may find it preferable to a 90 degree angle. Alternatively, if you have a countertop already, but you are dissatisfied with the appearance of its edges, this technique may be the exact thing that you are looking for. While doing this requires many special tools, there is no reason not to do it yourself if you have access to them. What follows should give you all of the information you need to bullnose your own travertine.
Step 1 - Setting Up
Before you do anything, you will have to choose an area to work. If the travertine that you are working on is already installed, as a countertop or other form of tile, the decision has been made for you already. In this case, all you need to do is seal off the room you will be working in to avoid spreading dust around.
If your travertine has not been installed yet for whatever reason, your task is slightly more difficult. Finding the space to work on a large section of travertine can be quite difficult, particularly when you realize that your work surface must hold the travertine steady. Chances are good that you will need to find either a large, sturdy work table or use several sawhorses to hold your travertine while you work.
Step 2 - Planning the Job
In order to bullnose travertine effectively, you will need to decide how round or sharp of an edge you desire. Once you do this, measure a line parallel to the edge you wish to bullnose. This line should be close if you want a sharper edge, and far if you want a rounder one. Once you have used your tape measure to do this, mark off the line you have measured with masking tape.
Step 2 - Grinding the Edge
First, put on your protective clothing. Once you have done this, get out your grinding wheel and use it to go over the edge of your travertine that you have marked off. Your goal is to grind very evenly, not finish grinding on the first try, so be prepared to go over the edge many times.
Step 3 - Finishing the Edge
By the time that you have gone over the edge for the tenth time with your grinding wheel, you should see the shape that you want forming clearly on the edge of your travertine. When this happens, put your grinding wheel away and get out your grinding disc. Start out with the lowest grit disc that you have. 100 grit is probably the best to start off with, but you may start off with a higher one if that is what you have available. Use the grinding disc on the edge, then slowly work your way up all the way through your discs until you are using the highest grit one that you have, preferably at 1500 grit or close to it. In between grindings, wipe off the travertine with a damp cloth to remove any particles.
Finish up by using a 3500 grit disc on your travertine.
