How To Fill Holes In The Wall Without Leaving Visible Marks.

If you are looking for more info on home improvement, so we compiled some info and wrote this content. Maybe you’ll find it useful.

You’ve decided to repaint – however when you took all of the pictures off the wall and moved that big cabinet, you were left with a surprise number of tiny holes, cracks and bumps. You purchased really high quality paint. You really don’t feel like wasting it by painting over these  marks and blemishes – especially since you were planning to replace the big cabinet with a flat- screen TV, and change the location of all of the pictures. The truth is, the ten minutes you spend filling holes and repairing cracks will bring you hours of satisfaction as people compliment you on your beautiful, professional paint job.  (Or in the minimum, don’t say “Gee, I never saw that crack before…”) And when you do your repair like a professional, you’ll thank yourself forever afterwards for your results.

Besides your planned painting supplies, you will need:

*Sandpaper

*Hand sanding block (to mount sandpaper on)

*A small pot of filler appropriate to the surface being filled

*1” putty knife (plastic)

*4” drywall knife

*Safety glasses

*Sanding dust mask

*Tack cloth (for magically lifting dust from a freshly-sanded spot)

Based on what you’re repairing, your sandpaper should be:

*120 grit for drywall compound

*A number of grits for glossy woodwork

But How About Stains?

Sometimes the blemishyou would like to cover is a stain. Permanent ink marker, for example, is notorious for bleeding through new paint – you can’t just paint over it!  When confronted with a stain that won’t come off easily, it’s always best to paint the area first with a sealant such as Kilz (found at Home Depot stores.) First, finish the repair and sanding of all of the cracks, then apply the Kilz. Kilz is also good for permanently eliminating cigarette smoke, when you are taking over a room from a habitual smoker. When you just paint over it with latex paint alone, you’ll find the smell  returns after a couple of weeks – or days.  But do spend the extra bucks necessary for a can of Kilz, when you have the above  problems.  How heartbreaking would it be if that marker scribble bled through your beautiful  faux suede Ralph Lauren paint – and you had to stare at that mark, day after day?

We’re All Set To Go – Almost

If your wall is really greasy or dirty – especially from smoke damage of any sort – one great  precaution is always to give it a wash with a solution of T.S.P. salts. Realize that T.S.P works like a dream in lifting grease and prepping your wall for painting – but it’s extremely corrosive on  skin and banned in some States. (Ask your Home Improvement store professional for a substitute).  It is essential for you to wear HEAVY GLOVES when dealing with T.S.P., and  avoid splashing yourself with it at all costs.

That being said, it’s odorless and one of the least likely chemicals to cause any problem with  inhalation.

 

Repairing That Crack

The standard rule to remember: When the crack over ¼” wide, you will need drywall tape  for a successful repair.

The second rule:  Drywall compound will shrink on drying.  You will probably need at least 2  coats.

Make certain your piece of drywall tape is at least 2” longer than the crack itself.   Spread a very thin layer of drywall compound over the crack. Apply the tape and push in firmly (although not too hard, or you’ll squelch the drywall compound  out from under the edges.)  Use your fingers Smooth the tape flat together with your drywall knife if the crack is very small, omit the drywall tape, and just fill

Use a special filler for wood, when filling cracks in woodworkyou want to paint. If the surface  was in the past painted, sand first and wipe before filling.  If the wood was varnished, and  you’re painting over it, use a variety of grits (starting with the coarsest and working your way  up to the finest) to sand off as much of the existing glossy surface as you can.  (This works on small  areas; for instance when you have decided to paint previously varnished wood trim or baseboard.  For an entire paneled, varnished wall, talk to your store professional, because this is a substantial undertaking.)

Once all the drywall layer compounds are completely dry, it is now time to sand the surface.  The best option for sanding a flat surface is a sanding block.  Be careful if you choose not to use a sanding block. using sand paper alone tend to lead to creating a concave depression while spot sanding. Wipe using a tack cloth, and repeat your fill, if necessary. Don’t stop until your surface is  absolutely smooth and flat. After you have completed these important preparation steps, now you are finally ready to start painting.
