Crack Tape

Strait Flex sent me a bunch of samples to try out. One of the products was call Crack Tape. And I just happened to have a few cracks needing fixing, so I thought I would give it a try. If you read my article on repairing drywall cracks that occur at the corners of windows and doors, you find that I am not too optimistic about any type of retaping holding up. Rather, I advocate removing drywall and putting up new pieces so there is no joint at the corners. But, this Strait Flex product is advertised to have 10 times the strength of regular paper tape. So maybe it would hold up?

I repaired one crack by simply taping over the top and then overcoating and feathering out the repair. Since this tape itself is a bit thicker than paper tape, it raises the surface a bit, which is never a good thing. But, on the other hand, this Strait Flex is a stiff non-paper composite material that is sand-able. So unlike paper tape, if you happen to sand down to the tape it is not as detrimental. My repair came out nice and is shown below.

I repaired another crack by using the drywall crack repair method shown here, but instead of using paper tape, I used the Strait Flex crack repair tape. The repair went well, and I would expect that the repair would hold up better in this high-stress area than regular paper tape. Another feature of this tape, besides being much stronger, is that you place the tape on, imbed it, and then immediately place a coat over the top. This allows a continuous coat to pass through the holes of the tape, giving it that much more strength. And since this tape is fairly stiff, I had no problems with snagging the tape by immediately overcoating. Check back at this site in 5 years or so to see how well it held up

Going Over The Top of a Crack

Black Mold on Drywall!

Our bathroom was getting mold on our ceiling and walls within 3 weeks of cleaning off the walls with straight bleach during fall and spring months. During these months, the inside humidity could be fairly high, yet a quick dip in outdoor temps could create cold spots on walls and ceilings. And to compound this even more, the hose on our bathroom fan disconnected at some point, venting damp air into the insulation. So I tore off all the ceiling drywall and exterior drywall, removed insulation, cleaned things up, and brought both my ceiling and exterior wall in 2″ to allow more insulation and increase the R-value. I also did a bang-up job on insulating my attic with brand new insulation using insulation chutes near the eaves. I replaced our tub and shower too as it had some cracks. I must admit this was a big job but I am glad I did it - mold is not something I want in my house! See removing black mold in drywall for details on this project.

What is the biggest difference between the horrific drywall work I did in my first few projects and the work I have done in my latest projects?

It takes me a lot longer to finish my drywall!

That sounds almost contradictory. After all, should one get faster, not slower? Not really.

When I first started, I gobbed the compound on, sculpting the thick layer with my taping knife, leaving it way too thick. Then, I followed with a good sanding. But things did not look right, so I gobbed on some more mud, let it dry, and sanded some more. At this point, I had all the compound I needed, so I just kept sanding. And sanding. And sanding. Finally, as things started to “level out” a bit, I started hitting paper tape and the paper drywall board. Sanded paper = fuzz. Oh well, the paint will cover . . . (wrong again!) I finished my wall in two days but it looked like a 6-year old’s art project.

Now, I put on the mud but take most of it off with a smooth stroke of the wide taping knife. Not two coats, but rather 4 or 5 along with some touch-up mudding. And I don’t touch the sandpaper till ALL coats are on and the surface could almost pass without a sanding. I now “knock” the surface down where needed with a taping knife. So now, it takes me nearly a week to finish a wall. But it looks like it was done by a good professional! (A good professional does not need to cover blemishes with texture). I use all-purpose compound for all coats. I guess if I were doing this for a living, I would use some faster drying compounds for the first coats. But as a DIYer, I am in no hurry.

Another 1/8" Deformation Since Last Time

It has been 3 months now since I first hung 23.5 pounds on a single Hercules Hook on a 1/2″ drywall panel. And it is still hanging, although the hook continues to deform, slowly but surely. As you can see from the photo, the hook has deformed another 1/8 inch or so since I checked 2 1/2 months ago. So now there is about 1/4″ of total deformation as compared to a new hook.

Also, the hook is starting to dig into the drywall where it hangs, with a total of about 1/8″ so far.

I have placed the weight back on the hook. The next time I post will be when my 23.5 pounds falls out. See you later on this topic!

Two 3-inch Mini Paint Rollers

The mini paint roller has quickly become my favorite tool for repainting a small drywall area that has been repaired. I used to use a regular size roller - my wife was always the one using the diminutive 3″ roller. And you really should always use a roller to finish the painting or priming - a brush or even a foam brush will leave streaks or brush marks where as the roller will blend your repair in nicely.

What I found was that the mini roller does just as good of a job finishing the surface and only takes a little bit longer to roll on paint on a small repaired area. The BIG advantage of the mini roller is that you can dip the roller directly in the paint can, thus eliminating the need for a messy tray to clean up. Also, the mini roller itself is much quicker to clean - you can fill up a mop bucket full of hot soapy water and clean the roller in this water very quickly.  Factoring in the savings in cleanup time, the mini roller cuts the total painting/cleanup time in about 1/2 for a small area painted. Another plus of the mini roller is that you can use it on narrow regions where a full size roller won’t fit.

Another good way to use the roller is to apply paint with a wide foam brush and then work the 3″ mini-roller into the paint. This allows you to put a fair amount of paint on without dripping.

Another good idea by my wife.  But please don’t tell here I said that!

Here is the nail pop!

What Causes Nail Pops?
Nail pops occur in drywall that has been secured with drywall nails as opposed to drywall screws. This commonly occurs in homes that are 30 or more years old but can also show up in newer homes. The nail pops are due to the nail working its way out which is caused by shifting of the structure or can be caused simply by someone pushing against the drywall (like next to a bed). In older homes these nail pops are to be expected and there is no need for concern.

Repairing Nail Pops is as Easy as 123!

Drive in the nail pop with several screws

To fix nail pops, simply drive in two or three screws next to the nail head so that the screw head pulls the nail head in below the surface. The screw heads should also be driven below the surface. You should use a star drive deck screw like the one shown here as it takes a lot of torque to drive this screw and you will have a difficult time with a regular drywall screw. Also, the head of a regular drywall screw may snap off. Once you drive the screws in, simply fill in the depression with a few coats of joint compound and sand level, taking care not to sand off a layer of paint. Then prime and repaint.

Fill, finish, prime and paint!

About an eighth of an inch deformation of the hook

After 2 weeks with 23.5 pounds hanging from one hook, I inspected the Hercules Hook. It had straightened out ever so slightly. About 1/8″ deformation of the Hercules Hook was observed. I measured deformation by placing the hook next to an unused hook.  The Hercules Hook from this experiment is shown next to an unused hook in the photo on the left.

I placed the Hercules Hook back into the drywall with the 23.5 pound weight back in place.

With what I know now, I would not recommend hanging extremely heavy objects (over 20 pounds per hook) from a single Hercules Hook in a drywall wall as I would expect deformation to continue with time. I would, however fully recommend this product for hanging lighter objects like framed photos weighing less than 10 pounds.

In two months I will check on this hook again and see if there is any further deformation.  I will then post my findings.

23.5 Pounds Hanging On Hercules Hook

A few weeks after I bragged about how well the Hercules Hooks worked in hanging our heavy portrait, wouldn’t you know it - my wife had me move the portrait a few inches down :)  When I removed the hook, to my surprise, I saw that is was 2/3 of the way straightened! It looked somewhat like the hook did in my first Hercules Hook trial that failed when my daughter pulled the hook out of the drywall.

Two things come to mind: 1. Either the hook is straightening slowly with time under the heavy load . . . OR . . .  2. The hook is catching on the insulation of this exterior wall and thus can not function quite like it should.

At any rate, I rehung the heavy portrait with one screw in a stud and one hercules hook in the drywall. This allowed me to hang the photo centered where we wanted, yet gave me a little insurance with the picture wire draped over the screw. I would recommend this solution for any very heavy portrait or mirror.

With respect to the question: “Will the hook straighten out under heavy weight if properly hung?” I decided to conduct another trial. I have hung 23.5 pounds of weight on a hook and will check the condition of the hook after several weeks and perhaps check it again after several months.  The weight is shown pictured on the left. The hook is in drywall that has no insulation in it, thus it is allowed to function as designed.

Stay tuned!

Held Up With 1 Hercules Hook

Well, I had the opportunity to hang something other than my kids up on the wall in the last few weeks with my hercules hooks. Hung a few small framed photos on the wall. The hooks worked nicely. And then, just the other day, I had to move a very large framed photos weighing perhaps 15 or 20 pounds. This was an artist’s sketch of my kids placed into a custom matte and frame. This picture is of great value to us.

The center location was not on a stud. Ordinarily, in a situation like this, I would at minimum, use a molly bolt rather than a flimsy drywall anchor. And I definitely would not use only a drywall screw for this heavy of a picture. But this time, I simply used a Hercules Hook. I marked where I wanted it and poked it in and gave it a twist and I was done! About 30 seconds!

For hanging pictures, these hooks are the best! Don’t take Billy May’s word, take mine - I would not promote them here if they were junk. I was able to get a large pack of these hercules hooks at ebay for under $10.

Every once in a while, we will watch As-Seen-On-TV infomercials, mostly for entertainment value. Nearly all cost $19.95, are the best thing since sliced bread, and include bonus items that result in a “total value” many times the price. And wait, there’s (always) more. . .

Hercules Hooks, however, seemed like they could actually work. So I ordered a bunch to check them out myself. To test these, I had my kids sit on a very low (and safe) platform that was about 11″ off the floor, supported by ropes hung from two Hercules Hooks.

The first claim I tested was the ease of use. The hooks went in very easily, although I need some practice to achieve Billy May’s speed!

Then I tested the weight carrying claims. The As Seen On TV ad claims they support up to 150 pounds, but if you read the fine print on The Official Hercules Hook Website, they say “For heavy objects over 40 lbs. use multiple hooks to distribute weight evenly”. So I decided to use two hooks to see if I could get the 80 pounds of carrying capacity they seem to imply. I had my 60 pound daughter sit on the platform - no problem. Then I had my 77 pound son Mark try it. He carefully lifted his feet off the floor and the platform supported him. Then, I had Laura, who weighed 83 pounds, sit on the platform. Laura was OK until she tried to lift both feet off the floor. Then one side pulled out after the hook straightened a bit. So when they say 40 pounds, they mean 40 pounds! Watch The Video Here!.

Finally, the hercules hooks do not damage the wall much. A little dab of drywall joint compound or spackle, or just some paint alone could repair the holes left. Even where the hook pulled out, the damage was minimal.

In conclusion, I would recommend these hooks for holding no more than 30 pounds per hook. So a single mirror on one hook should not weigh more than 30 pounds. You would not want to push the 40 pound limit, as any external force pushing down (like cleaning the mirror) could result in the hook straightening. The same goes for items hung on two hooks - do not put anything heavier than 60 or 70 pounds. With respect to the 150 pound claim, I believe you could indeed support the 150 pounds with 4 hooks, but the weight would have to be distributed perfectly.  So if two of the four hooks were not quite lined up to support weight, the result could be as much as 75 pounds on each of the other two hooks. Getting 4 hooks placed in the exact correct locations might be tricky for some furniture items.

Basically, all the As-Seen-On-TV Hercules Hooks claims are true, provided you add an asterisk* by the Holds Up To 150 Pounds* claim to include a note “*Do not support more than 40 pounds per hook. Items requiring more than one hook must have weight distributed evenly on the hooks”. From the official Hercules Hooks Website statement, one might get the idea that two hooks could support up to 150 pounds. Even so, this easy-to-install hook can quickly hang pictures and items weighing up to 30 pounds or heavier items up to 60 or 70 pounds if two hooks are used. I would say it is a nice product to have around the house.
