How do you line up textured walls and a ceiling to regular painted drywall?

Our dining/living room has textured walls and celing, not the popcorn stuff. Someone went through a lot of labor to smear and design the pattern on them. Now in the kitchen, there is just regular drywall that is painted. We want to knock down the wall that separates the two areas and expand our kitchen. Our dilema is how to have the textured and smooth walls and celings meet without looking funny. We thought of running a wood beam across the celing and down the walls but the layout would have it run down the wall in a very very odd area and look totally dumb. We need a lot of suggestions! Thanks in advance.How do you line up textured walls and a ceiling to regular painted drywall?
You can sand the textured wals smooth...





You can fill the texture and smooth the walls.





Either is a mess...





Some consider it enough of a mess to just go ahead and rip the drywall that has the unwanted texture out then replace it. This is sometimes cheaper due to the low cost of the material and high cost of labor.How do you line up textured walls and a ceiling to regular painted drywall?
If the area is not that large then I suggest getting someone to retexture over all of it so that the area is all consistent. Or a cheaper version would to buy a few cans of texture and apply it yourself. If the area is large then you may consider completely retexturing. Hope this helps.
More than likely you will not be able to match the existing texture. I don't know if your talking about knockdown texture or a stomped texture. If it is knockdown, it is no problem to match it and it did not take whoever long at all to do that pattern. If it is stomped ceiling ( where drywalls coat the ceiling with wet mud and take what looks like a mop with half the mop head cut off and stomp it against the ceiling in a pattern) you will find it very hard to match. It would then be best to skim coat the entire ceiling and reapply texture.
you're going to have to retexture the whole wall %26amp; ceiling (new %26amp; existing) you have to patch the demo area, float the first coat, let it dry, sand it then put on the texture.
