Q:Our concrete slab for the porch was poured after the house was built and concrete was splattered on a door. How do we go about removing it without damaging the paint? Sandy :O)

Muriatic acid will do the trick. You can get it at most pool supply or hardware stores. Just pour some in a pail and dip a sponge or paint brush in and wipe it on the splatters. You may have to scrub a little but it will take off the cement. Don't forget to use gloves and make sure the area is well ventilated. The fumes can damage your nasal passages and lungs.

Q:I purchased metal spray paint for my front door. Besides cleaning, does it need to be primed? I have a interior waterbased primer sitting around, would that work? Or can I basically just clean the door, sand it and apply the spray without priming it? The current color is beige and Im spraying a hammered black. Thanks in advance.

I would not recommend using spray paint on an exterior door. The quality of most spray paint is not up to the job. and when it wears around the handles, it will be difficult to repair. I use automotive sealers tinted to the color I need when, I paint an exterior door. It is not cheap but, its practically bullet proof. That being said, if you cannot be convinced not to do this, I would remove the door, remove the handle, and put it on something solid. If it is not real hot do it out in the sun. Clean the door throughly with an all purpose cleaner. Scuff sand the areas you want to paint with 500 grit sand paper, or a grey Scotch Brite pad. Aggressive sanding with coarse paper is not necessary, and not recommended. You need only to dull the surface. Use care to avoid sanding through. Clean the surface with wax and grease remover, (bug and tar remover will work in a pinch). Use 2 rags, 1 to apply the cleaner and 1 to remove it. repeat until all the dust is gone and the door is clean. The door is ready to be wiped with a tack rag and painted. No primer is necessary, steel doors are shipped in primer. leave it in the sun to bake as long as possible, move to shade and allow to cool before reinstalling.

Can be better than ordinary tops a little bit. Finally, the general top of the top is not necessarily thick on the seal is good, hair loss, then do not have half a year into a bald. If you are the family for the top of the bar, then pay attention to the bottom of the width and top the height of.

Do what stores do hang a bell up so the door hits it when it is opened. Or you can get a door alarm. We got one from a place like Home depo it stuck to the our cabinet door inside the cabinet. When opened a very loud alarm would sound. It can easily work for any kind of door too since it sticks on not needed in nails or screws. We used it when our youngest two kids would sneak candy at night. We put the alarm on late one night we heard little foot steps down the hall. My husband I actually laughed knowing it would startle them. We heard a chair drag across the floor hit the cabinet. We then heard the alarm go off, a startled yell feet running fast back to bed. We didn't say anything to them but later that day my son said That scared me so bad, mommy. I won't do that again. lol They never did.
