The salt and alum should be dis-solved in 4 gallons of hot water, after which the molasses may be added to the mixture. The resulting clear solution is then added to the lime paste, stirred vigorously, and thinned with water to the desired consistency. This whitewash has a yellow tinge when first applied, but the color disappears in a few days leaving a white film.
Airless Tip: If you have somebody who can start masking off the trim, have them start on that while you convert the airless to a new color. When changing colors with an airless paint sprayer it is a good idea to have a second bucket filled half way with clean water. Place the intake hose in the clean water gently without getting the old color everywhere in the water. Take the tip out of the airless and spray all of the old paint out of the hose and back into its original paint bucket. Be careful when doing this that you recognize when the paint starts turning watery. When it does point the gun into the first bucket and spray until it looks pretty clean. It doesn't need to be perfectly clean. When it looks good, clean off the intake line in the clean bucket and get the old color off the intake line. Now place the intake line inside of your new trim paint.
Take your time there is no rush. There is nothing wrong with having your project take a couple of weeks.
After the siding of your home is painted you can now start on painting the trim. There are a couple different ways you can go about painting the trim of your house. The first way is to mask off all of the trim so that you can merely spray the trim color on to your house, and the second way is to roll the trim by hand. If you are the only person painting the house I would recommend rolling the trim by hand. The reason being is because it takes a long time to mask off all of the trim on your home compared to just rolling the face of the trim boards. If you have multiple people, it would be faster to have the helpers mask everything off while you start spraying the trim color.
Types of Paint. Water-based paints are usually referred to as emulsions and were traditionally used only for interior walls and ceilings. But recently tremendous advances in paint technology mean that water-based formulas, especially the high-performing acrylics, are available for all surfaces, from woodwork to metal, and for interior and exterior use. The advantages of these paints over oil-based ones is that they are cleaner, have less odour and are more environmentally sound. Brushes can be rinsed clean with water.
Treat yourself to a good lunch and forget the diet. It is amazing what some pizza or a good burger will do for the afternoon painting push.
