Q: Does HydraGUARD change the look of stone and grout?
Yes, color is enhanced (deepened) and enriched. If a natural appearance is desired do not use. Always test in an inconspicuous area before using.

Q: What types of stains and chemical does HydraGUARD protect against? 
• Typical household water-based and oil-based stains. Acidic products such as tomato juice, lemon juice, wine and coffee. Greases are more difficult to prevent staining. Immediate cleanup is recommended.

Q: What type of adhesive is recommended over the B-6000 Waterproof Membrane/Crack Isolation?
Only a modified tile setting mortar meeting ANSI 118.4 or better can be used. Using a mastic adhesive over the B-6000 will require a very long time to cure and in addition, is not recommended in wet areas.

Q: Which thin-sets can be used for underwater applications?
The PermaFlex 500 or 600 can be used for underwater applications once cured. Even better is the Permalastic and Permalastic Rapid.

Q: Do I need to use reinforcing lath in the mud bed before installing tile?
A: Currently the industry standard is any area greater than 65 sq ft does require lath. It is typically placed midway between the mud bed, dry pack half the total thickness of the mud, place the wire lath then finish it off to the required slope.

Q: What size trowel should I use when installing tile?
The proper trowel is one that will ensure a minimum bedding thickness of 3/32” (3/16” when using Medium Bed Mortar) between the tile and substrate and also will result in a minimum of 80% coverage for interior or dry areas and 95% coverage for exterior, wet areas or when placing natural stone.

Q: Can B-150 Epoxy Adhesive and B-7000 Epoxy Mortar be used for setting tile outdoors?
Yes, both the B-150 Epoxy Adhesive and B-7000 Epoxy Mortar can be used to set tile outdoors.


Q: What is the difference between an overlay and an underlayment?
Just as the term implies, an overlay is used over a substrate typically wood or concrete as the final floor surface. An underlayment is used under the final floor surface to help level or repair the floor prior to the final covering, which in many cases is tile, VCT or wood flooring.

Q: What primer do I use for Level Set self-leveling products?
Currently there are three primers that can be used with Level Set self-leveling products. They are the Level Set Primer, Level Set Primer Plus and Level Set Epoxy Primer. Level Set Primer is used for properly prepared porous concrete. Level Set Primer Plus is used when going over most non-porous subfloors, moisture mitigation coatings, steel, wood and properly prepared cutback adhesive. When doing decorative applications with the Level Set Wear Topping the Epoxy Primer is used as a sand broadcast priming system.

Q: When do I need to use the Moisture Guard Max?
Moisture Guard Max is designed to reduce the levels of water vapor transmission to acceptable levels for most adhesives, coatings and floor coverings. It can be applied to concrete with a relative humidity (RH) of 100% and can reduce 25 lbs of moisture vapor transmission to less than 3 lbs.

Q: Why must a primer be used for Level Set self-leveling products?
By using a primer it will assure bonding of the Level Set self-leveling product and help prevent the substrate from quickly absorbing the water that is in the Level Set self-leveling product.

Q: When using Level Set self-leveling products over a wood substrate is lath required?
Yes, when applying a Level Set self-leveling product over wood, metal lath is required. The lath required is 3.4 lb per sq yd fastened every 6 inches to the wood subfloor. Priming must be done prior to installing the lath to assure the wood does not absorb the water out of the self-leveling product.

Concrete Repair 

Q: What product is best to use for a spalled walkway or garage floor?
ProSpec Concrete Resurfacer is designed for applications ½” down to a featheredge and is polymer modified so it will bond well to old properly prepared concrete. It is fast drying and is walkable in 2 hours.

Q: What is SSD?
Saturated Surface Dry. Most portland cement based repair materials require the concrete to be in a saturated surface dry condition prior to the application of repair material to prevent a loss of water from the repair material and absorbed into the substrate. This is achieved when the concrete substrate is saturated with water and there is no standing water on the surface.

Q: What are the benefits of using an air entrained concrete mix like the Metro Mix 240AE?
When using an air entrained concrete mix you will notice an increase in the material’s workability and improved freeze/thaw resistance. When water freezes it expands and takes up more space than water. The air content in an air entrained mix will be higher than a traditional concrete. This higher air content will allow the freezing water to migrate into the intentional air voids without causing damage to the concrete.

Q: Which product is recommended for horizontal concrete repairs that require a quick turnaround time?
Products such as the Premium Patch 100 and 200 will achieve a high early strength and allow you to return to service quickly. Both are used for DOT roadway repairs where the highway/bridge must be repaired and open for traffic in a short period of time. When using these two products the repaired area can be opened to traffic within 1 hour.

Q: Can ProSpec Concrete Resurfacer be stained or pigmented?
Yes, you can add pigment to the CR to achieve a specific color or it can be stained once it has been allowed to cure the recommended amount of time. The cure time prior to staining will be determined by the manufacturer of the stain.
