Hi again! I am back after making some good progress on my Granite tile countertop. Man, it takes so long working with only 2 hands on weekends
I have ¾” plywood with ¼” Backerboard. I bought premixed thinset from home depot and applied it to the plywood. Then I set the backerboard to the plywood with 1-1/4” screws. I cut a hole for the sink in the plywood and backerboard. Now I am ready to set the granite tiles. I want to make sure I did not forget anything big before I continue.
1. What should I use for sealing the sink to the granite tile? Should I use regular "Kitchen and Bath Silicone Caulking" for this? Do I simply put a line of silicone under the sink lip that sits on the tile and press it down using the sink mounting hardware? Any recomendations on how much silicone to apply here? Should I try to force some silicone into the crack between the sink lip and the tile after the sink is in place?
2. As I understand from other threads in this forum, I should use caulk, not grout, between the tile and the maple trim that I made (by the way, it came out beautiful thanks to excellent advice I got from y'all). Should I do this caulking after I finish grouting all the tiles? Sould I grout this joint first before I apply the caulking?
3. I used Tung Oil (3 layers) to seal the maple trim, and the plywood. Is this bad thing to do? I have made some tables before and finished them with Tung Oil, so I thought I should keep the good thing going. I am not sure if this is a good sealant for a kitchen environment.
Thanks again for your help.
