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.
Fortunately, you can always get your primer tinted for free. Getting your primer colored the same as your paint will save you a coat of paint. Of course, I always recommend doing a minimum of 2 coats of paint so that your finish sheen looks consistent.
You can put it around a room and probably follow immediately with the finish coat. It can be applied with brush or roller.
Solvent or oil-based paints are used where a tough, durable finish is required for interior and exterior timber, masonry and furniture - although, as mentioned above, the new generation of acrylics and multi-surface paints offers viable alternatives. In general, brushes need to be cleaned with turpentine or white spirit.
Complementary colors are opposites, and if you look at a color wheel, they are directly across from each other. While complementary ones may seem kind of mysterious to a novice, you just have to bring to mind Christmas to find a great example that is familiar to everyone, red and green.By simply making these colors a little paler, you can make this color palette work really well. Color tones are important, because rust and moss, while still being red and green, do not scream 'Christmas'. If your choice of tones is bold, you will create an eye popping design. However, it is common to get off course.
Better still, you don't have to spend hours getting ready and hours cleaning up afterward. Premixed paints, electric-drill attachments and self-dispensing calking guns make short work of preparation. Cleaning up is a soap-and-water job for the rubber paints, or a quick dip in special cleaners for the oils. Disposable dropcloths and paper paint pails are used once and thrown away.
