Drywall Staining? Tannin Bleed from Recycled Paper?

News Flash: It looks like drywall manufacturers are cutting corners... AGAIN.

The first offence took place from 2001 to 2007 when Chinese drywall manufacturers were using left over coal ash which is a waste product of coal fired power plants. They were using this as a "filler" along with gypsum, the primary ingredient in drywall, to produce sheets of drywall. After the product was installed in homes it began to off gas. The sulfur off gassing will eat away copper, metal, door knobs, etc. and may be causing adverse health side effects. There is a website chinesedrywall.com were one could find more about it and to see if you qualify for a class action lawsuit or some sort of retribution should your house have been constructed with Chinese Drywall.

Example of Tannin Bleed
Today the current problem with drywall is "Drywall Staining". The problems of producing toxic drywall is in the past. Now it is just an issue of aesthetics. This is a fairly new issue for the construction industry specifics have not been nailed down yet. It is thought that the staining is caused from one of two souces: tannin bleed from the recycled paper facing or high alkaline sizing compound used in the manufacturing process.
The problem appears when latex paints soak into the drywall and the acids or tannin rises to the surface. The staining does not occur as much if the drywall is cured or the paint is drying a a well ventilated and warmer environment.

Here are some solutions to help reduce the likelihood of bleeding:

  1. Perform a test on a scrape peice of drywall before proceeding with painting. It is important to also paint over a small test section of dried drywall compound as the problem with drywall staining has not yet been discovered. 
  2. Never add water to the paint as water(latex paints) seems to be the chief catalyst of the problem.
  3. Use the absolute highest quality primer/sealers. It is important to purchase drywall sealers instead of PVA primers. We have not found any significant advantage of using PVA drywall primer. 
  4.  Follow manufacturer's drying times for primers and top coats. if you apply top coats too quickly to wet sealers the tannin will have a medium to travel through and "float" to the surface.

Top 10 Odd House Paint Colors!

The human eye can perceive 10 million different colors. 

Lets try to come up with a few paint colors: Red, Yellow, and Blue. That takes care of the basic color wheel. So three out of 10 million down. Lots of color names to keep coming up with. How about peach, sunset, sand, statio tile red, gray oynx, and so on and so on.

One thing paint manufacturers do to name colors is attach a feeling rather than a trying to describe the actual color. Instead of calling it Sand they give it a description like "A Day at The Beach". There may not be a color called "A Day at The Beach" but you get the point. With so many choices one can only shift the same words around so many times to produce unique color descriptions.

After naming a few hundred colors you just run out of options.  Just looking at the color charts of most home improvement stores makes ones eyes cross. Could you imagine naming them all? Wouldn't that be the best job on the planet? So in an attempt to name all of these hundreds of colors did some of the companies just become complacent, bored, or lazy in there naming regiment? Perhaps. Maybe that's why we have some of the colors below.

Here is a list of the top 10 paint name oddities:

  1. Dream I Can Fly (Benjamin Moore 769)
  2. Muddled Basil (Sherwin Williams 7745)
  3. Urban Putty (Sherwin Williams 7532)
  4. American Cheese (Benjamin Moore 2019-40) 
  5. Cinnabark (Home Depot UL130-22)
  6. Garden Element (Diamond Vogel H17 7838)
  7. Leather Bound (Sherwin Williams 6118)
  8. Polished (Home Depot UL200-11)
  9. Painters White (Home Depot UL260-13)
  10. Manchester Mood (Diamond Vogel J15 8478)

This is only our opinion. If you think that your color has an odder, less meaningful or useless name please comment below and we will start a visitor list of colors.

5 in 1 Painter Tool: Cleaning Roller Covers

A 5-in-1 or "painters tool" should always be close at hand... and here's why...


It may seem simple to us painters. However
lots of home owners have never seen this. 

This is a simple video demonstrating one of the many uses for this nifty five in one tool. By scraping the paint out of a roller cover you can clean the cover easier (and yes you should reuse your roller covers so clean em up ) and also putting the remainder of the paint back in the bucket gives the customer a small amount for touch ups. They will appreciate this the next time they want to paint over a nail hole. 

The roller cover being scraped is the Purdy Colossus 1/2'' nap. There wasn't enough paint in the roller to make another pass on the wall but looks can be deceiving. As you can see from the video there is a ton of paint left in the cover. 

We were playing around one day and filled up a 24 ounce drink cup after scraping out a 1.5'' nap 18'' long lambswool cover. But this is a bit of an unfair assessment since the cover was loaded up with paint and then scraped clean. Nonetheless its still a testament to the amount of paint left inside of a cover when cleaning up.

Wooster Wide Boy Bucket Liner Experiment: Complete Success!

Using an 18'' roller is the greatest thing you can ever do while painting walls. it Speed up the process by 200%. The math is actually very simple because its twice the length of a nine inch roller (No Brainer). But there is one nasty downside to using a such a large roller... the clean up process is the worst.
Wooster Wide Boy
The Wooster Wide Boy Bucket can easy accommodate rollers from 9 to 18 inches in length. It can also hole up to five gallons of paint. This makes it a huge advantage over a tray when you need to produce and distribute a couple of cut pots to painters. Simply dump the paint out of the cans you have already purchased and brush or 4" roll from those. The Wide Boy is also constructed of polypropylene and will resist build up. Although the construction material of the bucket will resist build up that doesn't meant that its easy to clean up. Cleaning this thing is actually the worst part of using the Wide Boy and probably scares off more than it attracts!

Wooster actually recommends lining the bucket with a 30 gallon trash bag and adding 2 Snap Screens so you can roll. The reasoning behind the snap screens is to keep the plastic from sliding around the inside of the bucket while you load a roller. So this reasoning is not the most sound. Didn't you line the bucket so you didn't have to clean anything? Now you have to clean some 2 snap screens. Wait!? Stop!? We are trying to make this easy right?

Masking Tape Loop
Wooster doesn't even sell liners for this monstrous painting bucket. One could only begin to imagine the cost of liners. It would be ridiculous. The bucket alone costs $37.99! That's a hard dollar amount for the DIY painter to swallow any how when they can buy disposable trays for around a dollar. The weekend warrior wants to lay down the coating and move on with watching TV, relaxing or something else other than painting.

Here is the secret to getting a plastic liner to stay in the bucket while rolling. It is such a simple little thing its stupid. Take a strip of making tape and roll it over onto its self. Place four masking tape loops at the bottom corners of the inside of the bucket. Place another two along the left and right side of the grid. In the photo to the left you can see the loops and the tape stuck to the bucket.

Lined and Ready for Paint
Now cut  roughly 30 inches off of a roll of 72'' 3m masking film and unfold it. if you don't know what the film is here is a link to an article we wrote about  3m masking film. Now line the bucket with the plastic making sure that the plastic will over hang the sides of the bucket. Secure it on the loops of masking tape and make sure that it is a tight and snug fit from loop to loop. When you are done it should look like the photo to the left. Complete the liner by wrapping masking tape around the rim of the bucket.

Crazy Fast Clean Up!
Now just dump paint into the bucket and roll as you would normally. Clean up is really fast now. Now more washing the bucket out with a rag hunched over a utility sink. Removing the liner is not just a simple tug. You will have to remove the tape from around the rim first and then slide your hands between the liner and the bucket to gently remove the loops or tape. Other wise your gonna end up tearing the plastic and the paint will leak through resulting in scrubbing out the bucket by hand. All will be lost. Its taken a couple attempts to figure this one out but we are happy to   share it with you.
