When using Vertical Instant Lock Adhesive, be sure to use our SRW Premium Caulking gun, or a caulking gun with at least 14:1 thrust ratio.

Yes. SRW Rapid-Set Polyurethane and Superior Strength Solvent-Based Adhesives can be used on wood, metal, natural stone and clay. On steel surfaces, make sure there are no oils which will deter the adhesive to stick. Not for use on plastic, rubber, fiberglass or materials designed for continuous submersion under water. Quick Tip: for faster set up on steel and aluminum, scratch the surface

SRW Vertical Instant Lock Adhesive can be used on a wide variety of surfaces including:

  • Metal & Wood
  • Natural Stone
  • Manufactured Stone
  • Brick, Block & Pavers
  • Glass & Ceramic Tile
  • Veneers
  • Dry Stack
  • Masonry

Do not use on materials designed for continuous submersion under water.

Yes. Be sure to use SRW Superior Strength Solvent-Based Adhesive. It can be used on wet or frozen surfaces. The adhesive extrudes from the tube all the way down to 10°F (-13°C).

SRW Rapid-Set Polyurethane Adhesive can be used on dry or damp surfaces. (Reference our application temperatures found on product)

Flash the adhesive by lifting the cap or block for a couple of seconds to shorten the curing time

If the adhesive doesn’t seem to be sticking upon initial application, the surface may be too wet. Remove excessive moisture, reapply and set. To set faster, flash the adhesive to be sure it is bonding to both cap and block.

Yes, SRW Adhesive can be used on vertical applications. Vertical Instant Lock Adhesive is the best SRW Adhesive to use for vertical applications.

If using our other adhesives, be sure to adequately brace the project until adhesive can cure. Permanent horizontal bracing and/or mortar in the joints is recommended for Rapid-Set Polyurethane and Superior Strength Solvent-Based Adhesives.

Yes, SRW Adhesive can be used on fire pits. Keep the bead as far away from the heat source as possible. Do not use the fire pit until the adhesive has fully cured.

None of the SRW Adhesive formulas will freeze or be damaged by low temperatures. It is best to store tubes in an upright position to avoid excess extrusion. Apply Vertical Instant Lock Adhesive when product is at least 60°F (15°C) for easier extrusion.

SRW Fabric & Geogrid


Call us at 1-800-752-9326; we will gladly help locate a dealer near you! View Fabric or Geogrid products.

SRW fabric allows air, moisture and nutrients to permeate which create a healthy landscape. Plastic creates an environment where moisture can build up; this leads to mold, fungus and possible rotting of mulch. View SRW Fabric.

As a general rule and assuming the weight of the fabric is the same, woven fabrics will be stronger at any given weight than a non-woven. Non-wovens will have better water flow and ability to stretch instead of tear. View SRW Fabric.

All fabrics allow water to flow through, but some are designed with water flow in mind. Highest waterflow to lowest are:

  • Spunbond non-woven
  • Needle punched non-woven
  • Polyspun non-woven
  • Pro Plus
  • Woven

View SRW Fabric.

Polyspun nonwoven is ideally suited for weed control. View SRW Fabric.

As a general rule, most applications would benefit by having the fuzzy side down.

Reason: the fuzzy side tends to mix with the surface in which it is touching.

This mixing helps to hold the fabric to the soil. In an application where you are placing mulch over the top of it we recommend putting the fuzzy side up and it will assist in holding the mulch in place. View SRW Fabric.

SRW Geogrid is composed of high strength polyester yarns that are coated with a PVC material. SRW Geogrids are inert to biological degradation and are resistant to naturally encountered chemicals, alkalis and acids. It is typically used for soil reinforcement applications such as retaining walls, steep slopes, soft soils under embankment, sub-grade stabilization and waste containment/landfill applications. View Geogrid products.

Bidirectional geogrid is geogrid that is the same strength in both directions. It can be installed by either rolling out parallel along the wall if the width matches the design requirements for geogrid depth/length back into the soil or rolling out perpendicular to the wall and cutting to the correct length when the roll width doesn’t match the design requirements for geogrid depth/length back into the soil. Bi-direction geogrid is, typically, the lower strength grids such as our SRW Universal and SRW 3 Series. View Geogrid products.

Uni-directional or uni-axial and have the strength in the roll direction and MUST be rolled out perpendicular to the wall facing. The reason that the stronger geogrids are not made bi-directional is that it would be cost prohibitive because of the additional material that would be required. The cross machine strands are just strong enough to hold the material into a grid. View Geogrid products.

Geogrid is installed at the design elevations/block courses that are obtained from engineered wall facing profiles, wall cross sections, or geogrid placement tables. It is installed with the strength perpendicular to the wall facing. The geogrid is placed on top of the block and as close to the front as possible without being visible and is extended back onto the compacted retaining wall fill. The compacted fill should be level and flat so that there are no voids beneath the geogrid. The geogrid should be tensioned and staked or stapled at the rear to hold it taught before backfilling. Backfill should be worked from the wall facing toward the back or tail of the geogrid. Driving directly on top of the geogrid should be avoided. At least a 6” layer of soil should be on the top before being driven upon. Geogrid must be placed so as to have 100% coverage, butted together, but should not be overlapped. If overlapping is required, as in a convex curve, there should be at least 3” of soil between the overlapped layers. View Geogrid products.

When geogrid is not necessary;

If the soil is very good (free draining gravel or sand/gravel mix), no slope at the top of wall, and there is no surcharge (such as a driveway) at the top of wall, the exposed height of the retaining wall can typically be three times the depth, from face to back, of the retaining wall unit (i.e., a 12” deep block = 36” exposed height). For soils that are less than optimum (silt/clay/clay mixes) and with the above site configuration the exposed height of the retaining wall can typically be two times, and sometimes only one and one half times, the depth, from face to back, of the retaining wall unit (i.e., a 12” deep block = 24” or only 18” exposed height).

In all other cases your retaining wall will need geogrid. The nominal extra cost of geogrid is great insurance for the stability of your retaining wall. View Geogrid products.

SRW Paver Clean/ Paver Seal 


Call us at 1-800-752-9326; we will gladly help locate a dealer near you! View all Paver Clean products.

Polyhaze occurs when polymers from polymeric joint sand rise from the joints. SRW Paver Clean PW (Paver Wash) is ideal for tackling polyhaze. View all Paver Clean products.

Efflorescence is a whitish residue that occurs naturally during the curing process of concrete. SRW Paver Clean EF (Efflorescence) works well for removing efflorescence before pavers are sealed. View all Paver Clean products.

No, SRW Paver Clean products are not harmful as long as you keep plants and vegetation wet throughout the cleaning process. If in doubt, thoroughly rinse any areas where residual cleaners may have migrated. View all Paver Clean products.

SRW Products recommends waiting 28 days. It’s ideal to check with your paver manufacturer to determine their recommended curing times. View all Paver Clean products.

Yes, SRW Paver Seal products can be used on many Natural Stones. To be sure, review the user tips section on the back of every label to determine if it is the right product for your stone. View all Paver Clean products.

We suggest following the paver manufacturers recommended time frame before sealing. As a general rule, paver manufacturers recommend waiting 60-90 days after manufacture before sealing. View all Paver Clean products.

Yes, you can use our Paver Seal products on pavers after polymeric sand has cured for 28 days. Click to view SRW Polymeric Sand products.

The final step in installing polymeric sand is activation with water. Water saturates the polymers in the sand and allows them to bond. If water is not introduced during installation, humidity in the air can slowly harden the polymers without bonding the sand. Click to view SRW Polymeric Sand products.

In the event that a polymer haze or sand is setup on the surface, clean the area using SRW Paver Clean PW (Paver Wash) following the label directions. Click to view SRW Polymeric Sand products.

Concrete & Masonry Cure & Seal


Call us at 1-800-752-9326; we will gladly help locate a dealer near you! View our Concrete Seal products.

A true “cure and seal” should be applied in two separate applications. The first is at the time of the placement (cure) of the concrete as soon as the concrete has been completely finished and can support the weight of person walking across the surface. It can be applied by low pressure spray, or rolled with a low nap, good quality paint roller. SRW Sprayers & Slit Foam Rollers make the job easy!

In order for the cure and seal to be the most effective, it should be applied the day of the concrete’s placement to allow for proper hydration of the concrete, and to assist the concrete to achieve its maximum strength. Typical coverage rate of the cure is 300-500 square feet per gallon, no less than 300 sfpg.

Generally, as a sealer, the best time to apply it would be 28 days after the original placement of the concrete. Once again, the rate of application should be in the 300-500 square feet per gallon range. Do not over apply as it can lead to a whitish, hazy appearance which can be difficult to correct. Resealing of a concrete surface will depend on how much traffic moves across the concrete. A good rule of thumb is 3-5 years. View our Concrete Seal products.

X-treme & Select: Best for giving a high gloss, wet look

Green: Ideal for curing green concrete

True Seal: Invisible barrier from weather, salt and staining on unsealed concrete

Finishing Seal: Extra level of protection applied over existing film-forming sealer

A product that is 25% solids material (generally an acrylic resin), can be both solvent and water based, has a maximum allowable moisture efficiency of .40 kg/m2, and a coverage rate of not less than 300 square feet per gallon. There are lower solids materials, but those must be water based, and will not meet the ASTM C-1315 specification. View our Concrete Seal products.

The general answer is yes, but that answer should be qualified. If the project is new, and an unoccupied building, then a solvent base would work fine. However, if the building is occupied, and solvent odors cannot be tolerated, then you should be using a water base product. Even your VOC/OTC products generally have a solvent approved, but those too can be quite harsh. View our Concrete Seal products.

Concrete Fibers


All of the acrylic fibers including Hiper-Lon can be finished using common finishing techniques: power and hand troweling, broom finish, and colored concrete. Acrylic fibers will not protrude which makes finishing much easier. Click to view SRW Fibers.

AC50 eliminates plastic shrinkage cracking. AC60 is a 2-in-1 fiber that provides both plastic shrinkage protection and secondary reinforcement. Hiper-Lon is a true rebar replacement for many applications.*

*Check the Rebar Replacement Conversion Chart on our website for specific recommendations. Click here to go to the chart.

Each of these fibers can be pumped or placed using conventional equipment. Click to view SRW Fibers.

Acrylic fibers offer superior performance for all applications including: slab-on-grade, precast concrete, shot-crete, stucco, decorative, paving, and specialty concrete applications. Click to view SRW Fibers.

The main difference between the two fibers is that Acrylic fiber provides a deep chemical bond with the concrete paste, while the Polypropylene fiber provides a contact bond. Test results have proven that a chemical bond outperforms a contact bond. Click to view SRW Fibers.
