If you peak into the truck of a professional painter, you will find a lot of products that he or she uses to “save the day” and will make them look good when painting difficult surfaces. Bonding primers are one product that you will likely find. You will also find paint additives for mildew, flow agents, driers, and another you will likely find is Emulsa Bond.
Oil based paint has some qualities that you simply can’t get with latex paint. One of oil paint’s best qualities is the ability to penetrate into a substrate and “wet” a surface. This ability is particularly useful with bare wood and chalky or dusty surfaces. Oil’s ability to penetrate, wet and lock down can be “borrowed” by exterior latex paints when using Emulsa Bond as an additive to the paint.
An oil / latex paint
Adding Emulsa Bond (“EB”), makes your exterior latex paint an oil modified latex paint. This used to be done years ago with most exterior latex paints because they lacked adequate adhesion. These days, latex paints have improved with better resins and finer resin particle size, all of which aid in penetration and adhesion. Regardless of the advances in latex technology, there is nothing that penetrates better, or wets the surface better than an oil.
Even after pressure washing (see Cleaning Aluminum Siding for Painting), you will still have some hard clinging paint chalk left on the surface. Emulsa Bond will wet out and lock down this paint chalk. The amount of Emulsa Bond needed is different depending on the amount of chalk or dust, but the general rule of thumb is one quart to a gallon of exterior latex paint.
Pentrates into bare raw wood
Being an oil, Emulsa Bond will penetrate into raw wood deeply, providing good mechanical adhesion. Latex paints, having larger resin particles, do not penetrate very well. Latex paints rely on molecular adhesion which is in fact a “surface” adhesion. By adding Emulsa Bond to a latex paint, you will enhance the paint with the ability to penetrate and mechanically lock into the wood. The Flood Co., makes a solid color deck stain that incorporates Emulsa Bond as a prime adhesion ingredient in the product. You can also take advantage of Emulsa Bond in the same way for your own exterior house paint.
Make your own self priming paint
Much is touted these days about the self priming exterior paints. These paints usually carry a premium price. You can make your own self priming paint from just about any exterior flat house paint by adding Emulsa Bond to the paint. See Self Priming Exterior Paints
Use with flat paint for one coat work
Emulsa Bond can cause uneven gloss when used with sheen paints. For this reason, if you want to use Emusla Bond with a paint on a one coat paint job, you need to stick with flat paint to avoid sheen problems. There is no sheen with flat paint and therefore no sheen problems. If you are doing a two coat job, you can use Emulsa Bond in the first coat, then on the second coat use the latex paint only without Emulsa Bond and you will have a nice uniform sheen.
Don’t use in a second coat - no place for penetration
Use Emulsa Bond when you need the extra penetration - over chalky, dusty or raw wood substrates. It works well when used on rough sawn lumber too. If you have a clean, soundly painted, un-weathered surface you should not use EB for one coat work or in any second coat of two coat work. When Emulsa Bond can’t penetrate into something , it winds up on the surface with the latex paint causing “shinners” particularly where you have overlaps or lapping of the paint. If you get any shinners (even in one coat work), you can fix them by re-rolling the area with straight latex paint (without Emulsa Bond). Do this kind of touch up from breaking point to breaking point wherever possible for best blending.
Tweaking the amount of EB to use
The standard Emulsa Bond mix is one quart EB to one gallon of exterior latex paint. You may need more for heavily chalked surfaces (do an adhesion test to determine if you need more), or less for light residual chalk. Read the manufacture’s guidelines for more detail on EB mixes and amounts.
** Note: Emulsa Bond contains exterior mildewcides and exterior concentrations of mildewcides. Use only on exterior surfaces.
Binds chalk and dust
Emulsa bond has been used for years on aluminum siding repaints. The older white colored siding had a chalking type of white pigment used for the purpose of making the siding “self cleaning”. The desire was to have a chalk face would develop and slowly erode and wash down, taking the dirt and pollution with it, leaving the siding with a clean white appearance. Any aluminum siding paint that has been exposed to the weather for a number of years will chalk to some degree regardless of color.

Cleaning out your rollers and brushes
Since Emulsa Bond is an oil (in an emulsion), it does not clean out of your brushes very well with soap and water. Use the following procedure with brushes and rollers used with EB for best results.
Clean up brushes and roller covers with soap and water in the usual latex clean up way first. Then dip the brush into clean mineral spirits and re-clean, spin dry in a 5 gallon bucket. Then re-clean in soap and water, and rinse clean.
