There used to be a TV commercial which had a diminutive, computer analyst-type fellow in the checkout line of some hardware store, supplies in hand, with a couple of contractors in close behind him, slowly moving towards the cashier.
The TV viewer recognizes the little fellow as a do-it-yourselfer because he was wearing a fine dress shirt and dress pants, and everybody knows that amateurs, no matter what the task, be it cooking, painting, or even playing a sport, always wear their good office clothing while participating in such events.
The two gentlemen behind the little fellow were obviously tradesmen because they were both 260+-pound behemoths, sporting hard hats, while classily attired in torn blue jeans and timeworn bowling shirts with mustard stains that dated back to the 1990’s, because that’s what building contractors look like.
Regardless, the two professional contractors see the do-it–yourselfer is about to buy a bunch of cheap building supplies, so they tug the little feller out of the cashier line, remove whatever he has in his hands, then fill his arms up with better tools, with the lesson being buy what the pros use. Once through the cash, the three of them leave the hardware store laughing and giggling like a troop of schoolgirls.
In most cases, it’s better spending a little more money on quality products. However, when it comes to mudding drywall, how the pros work, and how they buy, isn’t always what’s best for the do-it-yourselfer.
Essentially, the amateur drywaller will lack technique, know-how and speed. As a result, his or her product choices will have to differ, at least in a few areas, from what the pros use.
When it comes to taping a joint, especially in the case of a repair, the amateur should consider using a Fiberglas tape. Professional drywallers commonly use a paper tape because it’s less expensive and can be rolled out and applied more quickly.
Fiberglas tape will stick to the drywall, unlike paper tape, which requires the user mudding the joint beforehand. Mudding, or adding joint mix to the seam, then embedding the paper tape into the joint compound, requires speed and technique, otherwise things gets messy, with joint compound spilling onto the floor.
As an amateur, methodically and patiently moving from one procedure to the next, and not speed, is what’s going to get you to the finish line.
After carefully placing the Fiberglas tape over the seam, the amateur can move on to the next step, mudding. The professional drywaller will choose either a beige or white all-purpose light compound. As amateurs, we’re going to go with the dust-control product.
Dust-control compound is heavier and thicker than regular light-joint compound, allowing the user to more easily scoop out a trowel full of mud, check their phone messages, go for a coffee, then calmly spread it on the wall.
Light compound is a lot thinner, and lighter, which makes it a whole lot easier on the shoulders and elbow joints of those professionals who work with this stuff for hours on end. However, light compound won’t sit on the trowel for long, so once it’s scooped out of the box, you had better be quick to get it on the wall.
Dust-control compound is also recommended for the amateur because the dust particles fall to the floor when sanded, in a controlled type of manner, hence the name. With the tendency of most amateurs to over apply the joint compound, followed by the need to sand things smooth, this is a key feature to avoiding dust everywhere.
Next, amateurs should invest in sponge sanders, a handy tool to avoiding dust when removing those not-so-perfect raised edges.
Where to copy the pros? The wider the swath of compound applied, the smoother the wall. So, invest in trowels by having four-inch, six-inch and eight-inch putty knives, as well as a 10-inch and 12-inch taping knife in the tool box.
