AGG Sealer Formula 888

AGG Sealer 888 is a heavy duty, high solids, solvent based acrylic sealer. AGG 888 enhances the natural colors of stone, while producing a durable, stain resistant barrier. AGG 888 is specially formulated to efficiently seal rough or porous surfaces such as Mexican Saltillo, deep wire-cut brick pavers, exposed aggregate, or any other rough or porous cementitious tiles or materials.

Surfaces treated with AGG 888 with have an enhanced look with a glossy finish. AGG 888 will help stone surfaces resist fading or discoloring from UV rays and will maintain gloss for long periods of time when applied to exterior surfaces. The level of gloss will increase as additional coats are added. For interior or exterior use.


AGG Sealer Formula 888



  • Mexican Saltillo

  • Pavers

  • Brick

  • Exposed Aggregate

  • Rough Stone

  • Concrete Pavers

  • Concrete Driveways


Always be sure the surface is clean, dry, and free from any dirt, grease, oil, wax, or other contaminants. Read the entire label before using. Use only as directed. Always test on a small piece of material or a small inconspicuous area to determine suitability. Ensure the area is well ventilated. Ideal surface temperature should be between 60°F and 80°F. Product works best when it is the first substance applied to the surface, insuring proper penetration.


For very porous surfaces: 1st coat: 75-150 sq. ft./gallon. 2nd coat 250-400 sq. ft./gallon. 3rd coat 500+ sq. ft./gallon.

For average density surfaces: 1st coat: 200-300 sq. ft./gallon. 2nd coat 400-500 sq. ft./gallon.

For very dense surfaces: 1000 sq. ft./gallon. Allow 24 hours between coats.


PAVERS: Apply with a solvent resistant paint roller having a 1/4 to 3/8-inch nap. Saturate paint roller and remove excess to prevent dripping. Roll sealer liberally, evenly, smoothly, and uniformly. Allow 12 hours to dry. One medium/heavy coat may be sufficient. Additional coats can be applied to increase gloss or even appearance.


NEW INSTALLATIONS- BEFORE & AFTER GROUTING: Apply with a solvent resistant paint roller having a 1/4 to 3/8-inch nap. Saturate paint roller and remove excess to prevent dripping. Apply one medium/heavy coat before grouting after tiles have been laid in place and set firmly. Roll on sealer liberally, evenly, smoothly, and uniformly. Do not leave voids and puddles. Work in small areas at a time. Let the sealer dry 12-24 hours before grouting. Clean grout and let surface dry 3-4 days to make sure the grout joints are dry before applying a second coat of sealer. Allow second coat to dry a minimum of 12 hours before applying a third coat if necessary. Gloss will increase as additional coats are added.

RE-APPLICATION: Remove any floor finish on the surface, and clean thoroughly. Allow 12 hours to dry before sealing. Apply with a solvent resistant paint roller having a 1/4 to 3/8-inch nap. Saturate paint roller and remove excess to prevent dripping. Apply one light coat and allow 12 hours to dry. Additional coats can be added if necessary, to add gloss or even appearance. After the sealer is dry, Top Kote Floor Finish can be added to give the floor a glossy finish and protect the sealer.

WIRE CUT BRICK PAVERS: Before grouting, apply a medium coat of sealer with a paint roller having a ¼ inch nap to help protect the tiles from sticking grout. Roll on sealer liberally, evenly, smoothly, and uniformly. Do not leave voids and puddles. Work in small areas at a time. Let the sealer dry 8-24 hours before grouting. Clean grout and let surface dry thoroughly(2-3 days) before applying a second coat in order to seal grout joint.

EXPOSED AGGREGATE: Apply one heavy coat with a ½ to ¾ inch nap paint roller. Let dry. Usually one heavy coat applied properly is sufficient.

STONE: For best results apply with hair bristle paint brush


Xylene or similar solvent can be used to clean tools.

Seal RX Enhance Stone Sealer is a heavy duty, solvent based, silane-siloxane designed to enhance color, impart water repellency and stain resistance to a wide variety of natural stone, concrete and aggregate surfaces.  The silanes react chemically and bond with the substrate to form an insoluble water-resistant treatment within 24-72 hours after application.




For properly prepared, unsealed natural stone, concrete walls, foundations, pre-cast concrete, block, brick and most aggregate surfaces.



Dirt, grease, grime and any foreign material must be removed before application of SEAL Rx ENHANCE.  Treat surface for mildew.  Oil and grease should be scrubbed with a solution of TSP and water.



Apply with brush, roller, airless sprayer or pump sprayer.  When spraying, use a tip designed for gloss coatings.  Apply when surface and air temperatures are above 32 Deg. F and rising.  Do not apply if the threat of rain exists.  Do not over apply or allow product to puddle.


  • Always apply a test sample to insure compatibility
  • Do not apply to a surface that was previously treated with another product
  • Take care to cover nearby vegetation, glass, plastic and metals. Seal RX 580 may damage them.
  • May be applied to damp surface, however, do not apply when standing water is present


SEAL Rx ENHANCE requires different application methods for smooth and porous/rough surfaces.


Smooth surfaces:

  1. Apply with brush, roller or spray
  2. Allow to sit for 30-45 minutes
  3. Wipe off excess material with a t-shirt type material. The excess should be removed similar to removing wax from a car.


Porous/Rough surfaces: No wiping is necessary as long as product penetrated and no puddles or excess material is visible.




SEAL Rx ENHANCE does not require thinning and should be used as is, directly from the container.




  • Enhances color of substrate.
  • Reduces water absorption into the substrate, thus reducing spalling due to freeze thaw and efflorescence, thereby increasing the life of the substrate.
  • Resists staining
  • Colorless and non-yellowing protection preserves the appearance of the substrate.
  • Penetrating & breathable
  • Low VOC
  • May be applied to damp surfaces
  • UV Resistant
  • Reduces mildew growth on surface




Finish: Enhanced look                                                          

Pigment Type:  None

Solvent Type: Solvent

Density:  8.50 lbs./Gal.

Viscosity @ 75 deg. F (24 deg. C):  Waterlike

Coating VOC: <50 g/l


Clean Up: Clean up drips and spills immediately using any type of solvent.  Clean tools and equipment with any type of solvent.


Coverage (Theoretical): Coverage will depend on porosity and contour of the surface being coated.  Coverage typically averages 600-800 square feet per gallon.


Storage:  After use, make sure to seal lid tightly.  SEAL Rx ENHANCE will gel if left open.


Environmental & Safety Information:

Improper handling or use may be hazardous.  Recommended safety precautions for storage, handling and application must be observed.




Contains flammable solvents.  Causes eye burns.  Vapor is harmful.  May cause allergic skin reaction.  Do not get in eyes, on skin or on clothing.  Wear eye and skin protective equipment when handling.  Wear appropriate, properly fitted respirator (NIOSH.MSHA approved) during and after application unless air monitoring demonstrates vapor/mist levels are below applicable levels.  Follow respirator manufacturer’s recommendations for use.  Keep containers closed when not in use.

First Aid:  In case of eye contact, flush eyes immediately with plenty of fresh water for at least 15 minutes.  Call a physician.  If inhaled, remove to fresh air.  If not breathing, give artificial respiration, preferably mouth to mouth and seek immediate medical assistance.  In case of skin contact, wash immediately with soap and fresh water.  Remove contaminated clothing and launder before use.  Discard shoes if material has penetrated inside surface.

Notice:  Reports have associated repeated and prolonged occupational overexposure to solvent with permanent brain and nervous system damage.  Intentional misuse by deliberately concentrating and inhaling the contents may be harmful or fatal.


WARNING! If you scrape, sand or remove old paint, you may release lead dust.  LEAD IS TOXIC.  EXPOSURE CAN CAUSE SERIOUS ILLNESS, SUCH AS BRAIN DAMAGE, ESPECIALLY IN CHILDREN.  PREGNANT WOMEN SHOULD ALSO AVOID EXPOSURE.  Wear an NIOSH-approved respirator to control lead exposure.  Carefully clean up with a HEPA vacuum and a wet mop.  Before you start, find out how to protect yourself and your family by contacting the National Lead Information Hotline at 1-800-424-LEAD or log on to
