Silox Anti-Dust Formulation
Online store for the sale of the “Silox Adobe and Rammed Earth Water Repellents” is temporarily closed to new customers. We are sorry for any inconvenience this may cause.
This water-based, environmentally friendly product was formulated to solve the annoying and damaging effects that the “shedding” of adobe and rammed earth can have on the expensive flooring on the interior of your home. Many people enjoy the look of untreated, raw adobe and rammed earth on not only the exterior, but also the interior, of their homes. Yet one of the problems homeowners oftentimes face is that both adobe (natural, cement and asphalt stabilized) and rammed earth “shed,” leaving particles of dirt and sand that fall on their flooring.
Adobe homeowners with expensive wood flooring, carpet and tile need to be concerned with this aspect of adobe and rammed earth so they can minimize the potential damage that can occur when these earth particles get ground underfoot. Antique furniture, heirlooms, paintings, household appliances, electronic equipment and clothing must also be protected from particles falling on them and becoming the cause of scratches, malfunction, or ruin.
Babies and toddlers, notorious for putting things in their mouths, may also be at risk from the sand particles and tiny stones that make up much of the adobe and rammed earth mixtures that fall to the floor or which can be easily picked or rubbed off from untreated earthen walls. Solve this problem with this special “anti-dust” formulation.
For interior use only.

SILOX ADOBE WATER REPELLENTS (Anti-dust)
Formulated for the particular needs of all adobe bricks, rammed earth, and earth type plasters for interior use.
Technical Data and General Information Sheet
SILOX Adobe Water Repellent (SAWR) (Interior Use) Anti-Dust Formulation (SAWR) is a small particle acrylic latex polymer specially formulated to help solve the problems of adobe homeowners experiencing the annoyance of their adobe walls “shedding,” and possibly damaging, their hardwood floors, carpets, tiles or other flooring products. SAWR is not only a penetrating product which helps to repel interior water but also preserves the surface by causing a chemical reaction that solidifies all component products into one solid mass.
Milky white water-based water repellent, easily sprayed with airless or pump-up sprayers.
If kept in a closed container and stored at an ambient temperature of 75 degrees F at 50% relative humidity, products shelf life is at least two years.
Most of the interior of new adobe homes need little surface preparation if the general rules of good workmanship have been followed. No special prep work need be done on the adobes themselves except the removal of any loose particles and “adobe dust.” If your adobes are dusty due to the adobes themselves, it is recommended you remove as much of this loose, dusty material as possible if possible. A wet/dry vac is excellent for either vacuuming up the loose particles or gently blowing the loose particles and dust free. It is preferable inside one’s home to vacuum up the dust on the adobes rather than blowing the dust free, for obvious reasons: you don’t want to fill your home with dust by blowing the dust free, which is why vacuuming the dust is better.
In new construction, the best time to treat the inside of your adobe walls with the Anti-Dust is when there is no furniture in the room, windows and doors are not installed, and the final, finish flooring has yet to be laid down. This job is then a breeze because you are not yet living in the home and you do not have to be concerned with the Anti-Dust getting on furniture or other possessions, nor do you have to be concerned with masking the windows/frames.
Living in the home while you are applying the Anti-Dust dramatically increases the complexity of the project. Now, everything must be either moved out of the room or covered with plastic. Windows have to be masked and your finish flooring needs to be protected. It can be done, of course, but requires far more work, planning and hassles.
Pro-tip: when applying the Anti-Dust when you are living in the home, use multiple “mist coats” to prevent the product from running down the walls and pooling at the base of the walls. Make certain when you apply all other subsequent mist coats after the first mist coat that you apply them “wet on damp” and never “wet on dry.” In other words, do not allow the first mist coat to thoroughly dry before putting on any subsequent mist coats; apply any and all additional coats over “damp” coats, or coats that are have thoroughly absorbed the first coat but are still damp and wet to the touch.
You don’t have to be concerned about removing each and every small particle of dust or loose material from your adobe walls: the Anti-Dust will bind up these loose particles and solve the dusting problem. But removing as much of the dust as you possibly can before you apply the Silox is always the best practice.
Air and substrate temperatures should be at least 55° F and rising. Spraying the Anti-Dust when temperatures are below 55° and falling should not be attempted. Thoroughly mask all windows with plastic masking and remove and/or mask any wall hangings, furniture, fixtures, etc. that could receive any overspray. If new home with no carpets yet installed, have water available at hand to dampen concrete floors and dilute sealer if and when it runs on them. Excess Silox on your raw, new concrete will not hurt it as long as you dilute it to a thin, 1% milk consistency and will act as an excellent primer for tile.
SAWR Anti-Dust will not harm your concrete floors if you simply dilute sealer which gets on the floor before it has a chance to thoroughly dry. Use plastic or canvas drop cloths to completely protect any carpeting. Caution: New earth adobes mixed with some asphalt emulsions may not react well with SAWR due to the reaction characteristics between oil type products (asphalt emulsions) and the water-based SAWR. These problems diminish as the new adobes are allowed to weather in the sun and elements.
We recommend doing a test area first to determine compatibility, and also that the SAWR be applied to these type adobes near the end of the construction process.
For best results, use low pressure airless spray equipment, backpack sprayers, or pump-up garden sprayers. Brushing and rolling this product is not recommended. When pouring the Anti-dust into the mouth or opening of your manual sprayer, use a one gallon strainer bag carefully fitted into the mouth or opening of the sprayer and pour the anti-dust through this to filter out any particles common in the formulation of the product. This will help to insure you will not experience any clogging of your spray equipment. These one gallon strainer bags are found in any Home Depot or similar home improvement stores. I have used them in my backpack sprayers for many years with excellent results.
The Anti-Dust product may have small particles floating around in the five gallon bucket or which may have settled to the bottom. As you pour the Anti-Dust into your sprayer, you may notice these particles. This is normal for this product and is nothing to worry about. Pouring the Anti-Dust through the gallon strainer bag will capture these small particles and prevent them from clogging your sprayer.
When using spray equipment, hold spray tip approximately 12-18 inches from surface and apply enough material so that the Anti-Dust floods the surface by using this method of application for the first coat. Use a gentle, drenching spray pattern in a fan spray and not a direct, pinpoint spray. Always work from top to bottom of wall in three to four foot sections at a time. Complete and total saturation of the substrate is needed to insure adequate anti-dust, protective properties.
Pro tip: Test SAWR in a small, inconspicuous area first prior to doing complete job. This will insure proper results and determine proper coverage and application. Allow this test patch to throughly dry so that you are satisfied with the amount of sheen left now on the area and that there is an adequate amount of anti-dust properties on the test area. Once the SAWR dries, you may not be able to apply additional coats to this area because the initial coat may repel any subsequent ones.
When first applied, SAWR emulsified resins appear milky white with a somewhat purplish hue. However, depending on the temperature and humidity of the air and also the substrate, these resins soon coalesce (fuse together) and dry clear and colorless. The milky appearance in hot, dry weather should last no longer than fifteen minutes. Strike out or roll out any obvious drips, runs or puddles after this time. Excess sealer must not be allowed to remain on surface after this time.
An application of a second, third or more light (or mist) coats is recommended for maximum protection. Apply this second coat just after the milky white appearance of the first coat has disappeared but before the first coat has a chance to dry. If the first coat dries, any subsequent coats may not penetrate through this. Open windows to allow drafts to blow through home to help dry and cure sealer. Sealer should dry within 1/2 – 2 hours of time, depending on ambient air temperature and humidity. Full cure in 24 hours.
Cold weather warning:
Cold and cool weather (beginning at approximately 50° F. and falling) can prevent the Silox from completely absorbing into your walls with the danger that some of the acrylic resins (the milky white, purplish hue) will not adequately penetrate into the adobe or rammed earth. This can allow those resins to remain on the surface and never disappear, even when the temps rise. This is why it is critical you spray the Silox on your walls when temps are 55° and rising—not falling.
Never attempt to apply the Anti-Dust with the temperatures near freezing nor when it approaches freezing. Remember: the general rule is only apply the Silox with the temps 55° and rising.
For most sun-dried earth and straw type bricks, expect approximately 40-50 square feet per gallon. Sun-dried asphalt emulsion type adobes: 50-70 s/f per gallon. Smooth troweled earth type plasters and rammed earth, expect no more than 60-90 s/f per gallon.
SAWR products are not recommended for below grade application or where water pressure is from the interior of the wall. It will not prevent water penetration through unsound or cracked surfaces.
