You scuff up existing paint for two reasons. First, you want to get rid of any oil, grease or dirt trapped in the top layer of paint. This is the stuff that cleaners and degreasers can't get off. The second reason to scuff is to set up a physical bond for the new primer and paint to adhere to. You want to give the old paint some tooth so the new sticks better.
Inside the house is where acrylic shines. It dries faster than other types, and it keeps its color better, without yellowing. One disadvantage: It costs more.
A good interior paint job is often 50% preparation and 50% painting. Do not rush in preparing the surfaces in your eagerness to get at the brush or roller. If you do not prepare the surfaces properly, you'll be back with the paint brush or roller in a few months.
Before you start painting, it is a good idea to keep an eye on the weather for rain or snow. You don't want to start painting only to stop abruptly because of the weather.
Emotional: I think every parent wants their child to be emotionally contented and stable, to have a strong sense of self worth and self esteem. Imaginative play gives children the opportunity to work through aspects of their lives they are struggling with. It allows them the space in which to examine and change and minimize consequences of their own actions and experiment with different end results to situations. This playing helps children "work through" difficult emotional situations and to develop positive coping strategies.
The principal ingredient in whitewash is lime paste. A satisfactory paste can be made with hydrated lime, but better results are obtained by using quicklime paste that has been slaked with enough water to make it moderately stiff. The lime paste should be kept in a loosely covered container for at least several days. Eight gallons of stiff lime paste can be made by slaking 25 lbs. of quicklime in 10 gallons of water, or by soaking 50 lbs. of hydrated lime in 6 gallons of water. After soaking, the paste should be strained through a fine screen to remove lumps or foreign matter.
Spend some time talking to the shop manager. He should have the time to thoroughly go over your options and explain their service and pricing. Be clear on what they're doing exactly. Will they scuff your existing paint? Will they be spraying primer? Are they OK painting any loose parts like bumper-ettes? If you're changing colors be sure to discuss the door jambs, trunk area and underside of the hood. Also, get instructions from the shop in writing for proper care of your fresh paint. It will include the number of paint curing days before you can wash it, wax it or let it sit out in the weather.
