Just curious.....which stucco method do you use in your stucco jobs?

What kind of wood flooring is already installed?

An existing t&g floor is an acceptable subfloor for an new floor. Ideally go perpendicular to the floor. So you have to remove all the baseboards in the room? Just make sure there are no loose boards, etc

When siding a gable, how do you leave room for the vent?

Ive have done just that. We only had an manual floor nailer (without air) so i had to really come down on the hammer to get through all that oak. It turned out great.

How about a floating floor over an existing hardwood floor. I have an old 1947 home hardwood has seperated and had carpet over it for about 12 years. Would like to put either hardwood down floating or nailed. Does anything have to be done to the old floor????? Thank for your help!!!!!!

What do you mean, the hardwood has "seperated"?

s. donato

if the flooring is separated you may want to solve that problem first. installing a floating over that will just mask the problem.

most of the time those old houses are just settling and pulling the joists causing them to separate. that's an issue b/c it may be a bad settle ie footer issues.

are they tight in the summer time? if so then its probably the humidity levels in your home.

Hello.
Here in Hawaii and California it is not recommended and licesed contractor is not supposed to do it.
Realty is that it could work and most likely would.
If there is some source of moisture say the crowl space het water in the rainy season, or there is bathroom close, loundry it is possible there will be sole expouse to moisture and this migt lift the old floor and new.
Considering that the old floor has been in the house for long time and never had problems then go ahead and do it.
Dont install the floor the same dirrection as the old floor if you go with nail down, floating doesn't matte rreally.
Now if you trying to hide some problems , not scraches but moisture problems you can be sure that sometime in the future the problem will get back.

Good luck.
Just make sure to use moisture barrier paper, and for floating extra moisture barrier can be thick paper.

Thanks for you help!!!! I am going to use an Meritage engineered floor 1/2" thick and nail it down perpendicular to the old floor. The reason I don't want to take the old 3/4" t/g oak flooring out is the mess and the house was built with old rough oak sawmill lumber. Hope it works!!!!! Thanks again for your help!!!!!!

Why do you have to lay the new wood a different direction from the old?...

gallerytungsten

It's stronger that way. You're creating a form of plywood.

Why do you have to lay the new wood a different direction from the old?...



my guess is this is a trick question..

answer is to offset wood grains to eliminate the bottom floor from opening the top floor from expansion..

on a 45 or perpendicular is guideline

I was just curious as to how it would be answered....
