Hi @Ryan1980,
Thank you for your question about what roller to use for coating travertine pavers with sealer.
I'd advise using a high-density foam roller with a short nap. Short nap rollers help you apply the sealer evenly without leaving an excessive amount of product or creating texture on the surface. They are ideal for smooth and consistent application, which is important for ensuring a uniform seal on travertine tiles.
You could use these UNi-PRO 9mm nap 160mm High-Density Foam Roller Covers with a UNi-PRO 160mm Mini Roller Frame.
This will give you a nice clean finish that will look fantastic for years to come.
Let me know what you think and if you have any further questions, don't hesitate to ask.
Jacob
