How do I lay tile so that the carpet lies seemlessly against (or under) it?

Question

I don't want to use a transition piece. I would like for the transition to be straight from tile to carpet. Know of any techniques for this? I've seen in people's houses that it looks like the carpet is actually tucked underneath the tile. How is this done? especially underneath the grout? I just don't understand I guess.
Also, I am using a 1/4" cement backerboard for the floor tile.

Answer 1

Addressing you first question, you'll need z-bar to lay the carpet smooth with the tile. The tack strip is nailed over the z-bar, which is an aluminum piece in the shape of a z, and the carpet is tucked under the z-bar. The tack strip nails are faced towards the tile and after installation you'll need to hammer the entire length of the tack strips or the nails will stick your bare feet. So in essence, the carpet abutes the tile, which must be laid straight and grouted prior to carpet installation. Frankly, it takes some experience and talent to do the job properly. On your second question, it depends on what type of existing floor you have. If it's concrete, no backer-board is needed. Just a clean and properly leveled and prepped floor. If it's wood, yes, a hardie backer is typically installed for the tile to bond too.

Answer 2

You need to make sure that the tile and carpet height will align when finished. Tile needs to have a substantial subfloor to avoid cracking so you will need more than a 1/4" backer if you have anything besides concrete beneath. The Tile Council of America recommends at least two layers of 3/4" plywood laid in opposite directions. Many contractors recommend topping the floor with luan and/or a leveling compound.
The edge of the tile where it meets the carpet needs to be kept clean. Apply grout only up to the joints perpindicular to that edge. Your carpet installer should know how to finish the edge at the tile. Remember to account for the height of any padding if it is being used. Good luck. :)

Answer 3

you cut the carpet 1/2 inch longer overlapping the tile then you take a wide chisle called a stair tool and tap it down using a hammer in between the tack strip and the tile and it looks better than a transition strip..it should then end up being the same hieght
