No Interior Bearing Walls and Be a Plasterer

floor trusses
You’re looking at magnificent floor trusses. These are spanning 28 feet, but you can go greater distances with ease. There’s no need for a bearing wall or beam under them to support the weight of the floor above. (C) Copyright 2018 Tim Carter

No Interior Bearing Walls

QUESTION #1: Tim, is it possible to build a multi-story home with no, or few, interior bearing walls or beams? I’ve looked at lumber span tables and regular lumber doesn’t seem to be able to do what I want to be done. What are my options and have you ever solved this problem before? Stewart F., Portland, ME

You

can build a multi-story home with no bearing walls. It’s been done for

decades. The most amazing thing about how to do it is one just uses

regular 2x4s to solve the problem! No, that’s not a typo!

Let’s

first discuss the span tables that Stewart mentioned. A span table is a

chart that shows how far a certain floor joist can span and not bend

too much depending on several factors. The wood species, the grade of

the lumber, and the height or size of the floor joist are the primary

things taken into consideration when creating the tables.

It’s

important to realize that different species of lumber have wildly

different strength characteristics. When I was building every day,

Douglas Fir was one of the strongest types of lumber you could buy.

Southern Yellow Pine was also very strong. Hemlock, on the other hand,

was somewhat weak.

Decades ago, I used floor trusses made with ordinary 2x4s to create the floor of a large room addition for a client. He refused to have any interior load-bearing walls or beams and also wanted a floor that was as solid as concrete with no bounce in it. Magic floor trusses solve problems like these and offer much more to architects, builders, and homeowners.

A

floor truss is made in a factory where common roof trusses are made.

Advanced computer technology designs the exact size and shape of the

truss to meet whatever specifications you require.

The

end result is a wood floor truss that looks much like large steel

bridges that span rivers and canyons. I’m sure you’ve seen hundreds of

these where the horizontal top and bottom members of the bridge are

connected by numerous other pieces of steel that look like a bunch of

connected letter W’s one after another along the side of the bridge.

This design can be done with steel, 2x4s, and even toothpicks for class

science projects!

Plumbing,

heating and cooling, and electrical contractors love working with floor

trusses. They have virtually unlimited places to run pipes, ducts, and

cables never having to drill one hole. The center of each floor truss

almost always has a wide-open chase for a heating or cooling contractor

to install his primary supply ducting down the center of the entire

floor from one end to the other.

A

floor truss can be designed to span 30, or more, feet with ease. The

truss manufacturer can build them so strong that there’s no bounce to

the floor at all. This comes in very handy if you desire a tile floor.

Tile and grout can crack if installed over wood floors that are springy

and bouncy.

Two

or three carpenters can easily move around these giant floor trusses.

You don’t need to have a large crane on a job site to set them. Each

truss is an identical copy of the one next to it so the finished floor

is flat and smooth with no humps or dips in it. These imperfections are

quite common with normal dimensional lumber floor joists.

You can discover lots more about floor trusses as well as the closest lumberyard near you that can order them for you. Visit: http://go.askthebuilder.com/bestwaytoframe

Since each job is different, these epic building materials are not a

stock item you can just go pick up today. This is why you’ve probably

never ever seen them before. I guarantee you’ll be spellbound when you

discover all that floor trusses make possible.

Be a Plasterer

QUESTION #2: Tim, the builder, I hope you can help me. A recent bathroom remodeling job turned into a larger project resulting in a large patch of wall plaster that’s got to be replaced. My contractor’s drywall people have never done plaster repair. How would you fix this 3-foot by 3-foot hole in the wall if it were your home? I’m tempted to try to do the plaster repair myself. Do you think this is a folly as does my husband? Ann W., Montrose, CA

Situations like this had to be part of the inspiration for the children’s book The Little Engine That Could.

My moniker around my home is ‘dream crusher’ because I often inject

reality into family discussions. More often than not in DIY situations,

my reality creates smiles. I say, “Get a simple plastering trowel out

and get to work!” Yes, you can achieve professional results with the

right attitude and some guidance.

You’re

blessed to be living in an age where technology permits the easy

sharing of knowledge. Quite a few professionals have invested vast

amounts of time and resources to create excellent step-by-step videos of

how to do thousands of projects. I’ve been doing it for nearly twenty

years and have over 650 DIY videos on my AsktheBuilder YouTube channel.

Kirk

Giordano is another example. He’s a professional plasterer that lives

and works in the Bay Area of California. He’s created hundreds and

hundreds of videos sharing his hard-earned knowledge about plaster and

stucco installation. 

Kirk is a great teacher and has several videos that show you exactly how to make the plaster repair that Ann’s facing. What if I told you that you could have the repair completed start to finish in less than two hours? The plaster you need is probably in a bag at a local plaster distributor not too far from your home or you can buy it online and have it delivered to your home!

The special plaster trowel you need with the curved corners is also affordable and readily available. You’ll be blown away when you see how easy it is to apply the fresh plaster and trowel it so it’s smooth. If you completely botch the job, then just chop it out and try again. But I’m convinced that after watching Kirk’s videos, you’ll get it right the first time!
