Rubber-base paints, which dry to a hard semi-gloss finish, may be used on concrete floors below grade, providing the floor is not continually damp from seepage and condensation.
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.
Now that you have the airless paint sprayer and your extension ladders it's time to paint your home. I would highly recommend painting the siding of your home first before painting the trim. The reason being is so you can just spray the house as fast as you can without worrying about painting a section of trim that you already painted. So paint the siding and soffit first followed by painting the trim. Painting the siding using an airless paint sprayer should go pretty fast.
Special Surfaces. WHITEWASH. Whitewashes and lime paints must be thin when applied. In fact, best results will be obtained if the application is so thin that the surface to which it is applied may easily be seen through the film while it is wet. The coating will dry opaque, but two thin Coats will give better results than one thick coat.
OK, let's get started. Step one...supplies. You need a flat brush, a fan, a small detail brush and a couple of Filberts. A filbert is a rounded edge brush that lets you maneuver the paint easily without going outside the edges. Ultimately buy brushes that you like though, and make them work. Fans allow you to blend, for example. I use fans a lot and it's how I graduate color throughout my images. Everything I paint is by hand....no airbrushing or assistants. I want it to be an expression of me and nobody else. You also need an oil painting medium to mix with the oil paint to make it more fluid, and to speed or slow the drying process. Whichever you prefer. Go to the art store and don't be afraid to ask for help....they'll love helping you! A medium is merely an additive liquid which increases gloss, makes it flow easily, preserves the finish over time, keeps it from yellowing. I personally love Galkyd and Galkyd Lite. If that isn't available, buy a medium that looks like liquid amber and is kind of thick. Don't buy watery looking mediums....too hard to work with.
TEMPERATURE OF COLOR. Colors have temperature, referred to as warm or cool. In painting, reds, yellows and oranges are referred to as warm colors and blues, violets and greens are referred to as cool colors. One of the biggest lessons you will ever learn about color temperature though, is that the appearance of color can change drastically depending on its surroundings. For instance, a certain yellow would appear much hotter if it were surrounded by a violet then say an orange. Another important lesson in color temperature: Warm colors will advance in a painting and cool colors recede.
Did you know when you walk in a room others size you up in just seven seconds? And, believe it or not, that's before you have said anything. Color is a big part of what makes up your appearance. The right colors will make you look younger, more confident, taller, healthier and bring out your natural beauty. The wrong colors will make you look tired, frazzled and can add extra years.
