Product FAQ's

  • How many square feet can be achieved with one gallon of Affinity?
    If applied over a non-porous substrate – 800 – 1000 sq. ft.
    If applied over a porous substrate – 250 – 500 sq. ft.
  • How long before it can be walked on?
    Affinity makes a covalent or molecular bond with the substrate it is applied to. It becomes a part of the substrate and is not to be compared to a sacrificial or mechanical coating/sealer that “sits” on top of the substrate.

Tips & Tricks
  1. Scan the QR Code on the bottle to quickly review a video of the mixing instructions.
  2. After cleaning the surface to be sealed, make sure it is completely dry including the grout on a tile floor/wall. You can use fans to expedite the drying process. For outdoor surfaces, such as natural stone, wait until the next day to apply the sealer as this then allows enough time for the power washed surface to be dry. Remember to make sure any outdoor sprinkler systems are turned off for 24-48 hours prior to application.
  3. If when applying Affinity to a surface, you begin to see the product pool or bead up, this is an indication that the product is rejecting the surface for some reason. When this happens, quickly spray 99% IPA onto the product on the surface and wipe it all up. You then need to readdress (clean) the surface as some sort of contaminant is still on the surface – for example, soap scum, wax, previous sealer, etc.
  4. Affinity can easily be removed if need be with 99% IPA up to 2 (TWO) days after application. After the 2 days, a stripper will be required to fully remove Affinity or you can profile the surface with a black pad and then reapply.
  5. Affinity is the most successful to adhering to the treated surface when the pH of the surface is neutral. Check the pH of the clean and dry surface prior to application.
  6. If you need to further neutralize the surface, mop the surface with white vinegar. This will help bring the surface to a neutral pH.
  7. It is recommended and best practice to work in a 2-person team. This allows one person to be spraying the product down and the other following and gently pulling the microfiber mop over the product. Also, be sure to have a slight overlap from the previous “lane”. Don’t forget to check for missed spots before getting too far away from the “lane”.
  8. When using a microfiber pad, be sure to spray the microfiber pad with the product and make it completely wet/soaked with the product. This will allow for a smoother application and less streaks.
  9. It is always recommended to add additional non-slip 220 grit to a surface wherever bare feet may come into contact with water on the floor. For example, always add non-slip to a shower floor.

Additional FAQ's

Ready-to-Use Affinity?
What type of sealer is Affinity – water-based, urethane based?
Affinity is a silane based, ceramic forming sealer, similar in chemical structure to glass that makes the treated substrate harder, impossible to stain and more scratch resistant.
How many components/parts make up Affinity?
Affinity only has two components, Part A and Part B. To mix Affinity, carefully pour the contents of Part B into the bottle labeled Part A. Replace the cap on the bottle labeled Part A and shake for 10-20 seconds. You are then ready to us Affinity.
What kind of bond does Affinity make to the substrate it is applied to?

Affinity makes a covalent or molecular bond with the substrate it is applied to. It becomes a part of the substrate and is not to be compared to a sacrificial or mechanical coating/sealer that “sits” on top of the substrate.

What kind of stains will be prevented by Affinity?
Affinity is extremely resistant to many types of stains such as balsamic vinegar, ketchup, wine and pickle juice to name just a few. There are very few substances that can break Affinity down or even stick to it such as the acidity in urine, gum, stickers or graffiti.

TIP: Affinity will even prevent hot tire marks on sealed driveways and garage floors.

What kind of chemicals will not break down Affinity?
Affinity stands up incredibly well against several chemicals. The following chemicals were tested after sitting on a sealed surface for 7 days with absolutely no penetration through Affinity – Acetone, Xylene, MEK, Tert-Butyl Acetate, Mineral Spirits, 50% Sodium Hydroxide, Ammonia, 1M Acetic Acid, 0.1M Sulfuric Acid, 1M Hydrochloric Acid, Motor Oil and Hydraulic Fluid.
What is the Pot Life for Affinity?
The pot life for Affinity is 7 days once you remove the foil liner from the capped bottles and you begin to mix Part B into Part A.
How long will Affinity be good if not used right away?
The shelf life of Affinity is one year as long as it is kept in a room that is no more than 80 degrees Fahrenheit.
Can I store Affinity in my garage or in the back of my truck?
Affinity should never be stored in an area where the temperature is more than 80 degrees Fahrenheit.
Can I take a gallon of Affinity and break it into my own half gallon kits, quart kits or smaller?
No, this is not recommended as each bottle of liquid material is placed under Argon prior to heat sealing the cap onto the bottle. Therefore, the second you expose the liquid to air, the 7-day pot life will begin, as the moisture in the air starts a low-grade reaction that if prolonged can damage the efficacy of the product. We currently offer Affinity in Gallons, Quarts & Pints.
Can I store any left-over fully mixed product in the refrigerator to use at a later date?
No, this absolutely is not recommended. The chemistry of our products is a precise and an exact science. If the product is placed in the refrigerator, there is a high probability that the product will fail, and RexPro does not warranty any product that is exposed to this type of climate.
How many square feet can be achieved with one gallon of Affinity?
  • If applied over a non-porous substrate – 800 – 1,000 sq. ft.
  • If applied over a porous substrate – 250 – 500 sq. ft.
What is the dry time of Affinity?
Dry to touch is approximately 2 – 4 hours, and dry through (to walk on) is approximately 4 – 6 hours – both at 70 degrees Fahrenheit and 50% Relative Humidity.

TIP: Fans can be used to expedite the dry time.

What is the full cure time for Affinity?
The full cure time is 7 days. However, the substrate can be used in general sense and furniture can be re-placed (not dragged) after approximately 6-8 hours. We recommend that the customer refrains from using any harsh chemicals on the surface until after the full 7-day cure time (for example, no Isopropyl Alcohol, bleach, acid, etc.).
What is the best way to clean a floor after it is sealed with Affinity?
The best way to clean is to use hot water and soap. It’s that simple and easy.

TIP: We recommend using our concentrated Safety Clean daily cleanser to not just clean the floor but to also increase the traction of the floor to prevent slips and falls.

How long will the Affinity last on a substrate?
In general, we estimate that Affinity will last approximately 3 – 5 years in a commercial setting and approximately 5–7 years in a residential setting.
Can I use Isopropyl Alcohol (IPA) from a local drug store or Denatured Alcohol to clean the treated surface right before applying Affinity?

We ONLY recommend using 99% Isopropyl Alcohol (which we carry) to quickly clean the surface to make sure there are no surfactants or soap residue right before applying Affinity as we cannot be certain what the “denatured” chemicals are or what the other %’s of IPA is. For example, with 70% IPA, the remaining 30% may be a lotion or liquid scent oil, etc. and those items may not be compatible with our product.

TIP: We always recommend having at least a gallon of 99% IPA on hand, not only to clean equipment, but also in case you need to quickly remove product that is pooling or rejecting on the sealed surface.

TIP: After cleaning the surface to be sealed, if the floor needs to be neutralized, mop the floor with white vinegar. The floor should be as close to a neutral pH as possible before sealing the surface.

How do you remove Affinity if you see it pooling or rejecting the surface it’s applied to?
As soon as you see any Affinity product pooling or rejecting, quickly spray 99% IPA on the product and wipe it up. You then need to readdress (clean) the substrate as something, such as a wax, is still on the surface and is preventing the Affinity product to properly adhere to the surface.
How do you remove the Affinity product after it has fully cured (7-days)?
If the Affinity has fully cured (which is 7-days), and the customer wants it completely removed, the only way to remove it is with our specially designed stripper for silane-based products.
Can Affinity be used over itself as a second coat?
Yes, but Affinity is designed to be a single coat In fact, it is designed to not stick to itself. However, that does not mean that a second application cannot be done.

TIP: A second coat would be required if the surface looks streaky or blotchy which is usually the result of not enough product being applied.

When can a second coat/application of Affinity be applied?
You can apply a second coat/application of Affinity after the product has fully cured for 7 days and with specific preparation techniques.
How do you reapply Affinity after it has been fully cured or has been several years since it was sealed but has now lost its gloss?
After Affinity is fully cured, you would want to use a black pad on a swing machine to break the tension of the sealed surface. You would then clean the surface, let it completely dry, wipe it down with 99% IPA, then Affinity.
How do you fix a small section that was either missed or did not have enough Affinity applied to it?

First you want to protect the good areas by taping them off. Then focus on the area that requires a touch-up or needs to be fixed by taking a green Scotch Brite pad to the surface and scuff the surface. Then clean the area, make sure it’s dry, and reapply the product.

TIP: You can use a black foam brush to fix small areas.

How do you add the non-slip 220 grit aluminum oxide to the surface Affinity?
You can add additional non-slip in a few ways. First, you can add it to the catalyzed product in the pump-up sprayer as it is thin enough to be sprayed out of the sprayer tip. Just keep shaking the sprayer so the non-slip does not settle to the bottom. Second, you can use a “puffer” gun or a gravity feed abrasive blaster gun (seen here) and “puff” the non-slip onto the surface immediately after you used the microfiber pad, then lightly mist the Affinity over the non-slip to secure.

TIP: Do not step on the already micro-fibered product. Apply the non-slip as you go. Do not walk back over the product to apply the non-slip.

How much non-slip 220 grit do you recommend to add to Affinity?
We recommend one to two ounces per gallon of Affinity.
