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.
Most of us look to save where we can, especially in this day and economic conditions. House painting is no different, when it comes to saving money. A home exterior weathers from harsh elements of heat, cold, sun, and snow, and exterior paint ages over time needing repainting. Exterior trim, being that of solid wood is normally the first to show signs of painting maintenance. Many times a homeowner happens to call, asking for only painting the trim. Trim paint jobs sound good at first, but have some underlying thoughts may have not been considered. Below are things to consider when considering painting trim only.
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.
You can put it around a room and probably follow immediately with the finish coat. It can be applied with brush or roller.
The perspective. Do you feel the distance between you and the painting? Are you an observer or a participant? The way you feel is dictated by the artistic choice - it's never a coincidence. An artist thoroughly selected the angle: you may look upwards, or downwards, or be at the same level with the objects depicted. If the horizon is at your eye level, the impression you will get is calm, stable. The high horizon will reveal more space, in landscapes it provides a majestic view. Paintings with the low horizon, so common with Dali, are monumental, highlighting the size of the objects and figures. The unusual views of Paris by Pissarro appeared as he painted from the hotel rooms.
Miniature paintings are executed on a very small scale on perishable material such as paper and cloth. The Palas of Bengal were the pioneers of miniature painting in India. The art of miniature painting reached its glory during the Mughal period. The tradition of miniature paintings was carried forward by the painters of different Rajasthani schools of painting like the Bundi, Kishangarh, Jaipur, Marwar and Mewar. The Ragamala paintings also belong to this school.
