Walls add a lot of beauty to the home décor if they are kept in perfect shape. In contrariety, a slip, a fissure or a crack can actually compound your home improvement miseries by a great deal. You need to ensure that just when a crack opens up, you get it repaired. There are plenty of DYI techniques that can be utilized for the purpose too. Lets read a little but about why the cracks open up first.
Why fasteners fail
Average adhesives and fasteners are not known to hold plastered walls too well. Sometimes, owing to temperature changes, the aspect of setting and shrinking of walls is introduced. This causes wide cracks too.
Dry wall compound cant yield big fruit
Cracks are of two kinds. The small, narrow ones and the large fissure like openings. If you have been bothered too much with narrow cracks on plastered walls, a joint compound or a dry wall compound can bring you out of your misery. Unfortunately, this does not work for big holes or cracks. This is because, despite being effective, it is prone to shrinking and hence causes a lot of setting problems.
What to do to repair cracks
The drying out of framing lumber can be an acute problem but it has plenty of solutions too. Of course, a mere spackling never works wonder. The walls look just as wretched once a day or two passes by. One perfect idea can be to use a can opener and scratch along the surface of the crack. The crack can be undercut or widened by simply holding the tip of the can opener. Use dry wall tape strips and gill the lacuna. Yes, the tape must be an adhesive bound mesh of fiber. Now, use a putty knife that is one third of a feet-knife and spread joint compound over the crack already covered by tape.
Three coats and proper blending
Use nearly three coats and perform adequate sanding. Remember to do it in such a way that the compound camouflages with the wall perfectly.
And to sum it up
Many people think that opening up the fissure area with a putty knife is an anti-repair process but then it has to be understood that only by opening up a further lacuna can you let the repair compound glue to the wall. Also remember to use a fiberglass tape or a paper tape only for the purpose. You must ensure that the feather dry compound extends two to three inches laterally beyond the taped area. Sanding is another process that you need to perfect if you want to give your wall a kind of chiseled look.
