KLINGSTONE PATHS
FAQ’S | BEST APPLICATION PRACTICES
WHAT IS IT?
Klingstone Paths is a liquid polyurethane resin that cures to a solid polymer when it reacts with moisture. For our purpose, humidity in the air is sufficient to cause this reaction without causing the resin to expand and foam.
WHAT DOES KLINGSTONE PATHS DO?
Klingstone Paths is drizzled over aggregate and coats the stones with a thin film that then cures to a solid polymer and binds the stones at their contact points. The resulting composite is very strong, yet permeable, since the void spaces between the stones are not filled.
WHAT ARE THE BENEFITS OF KLINGSTONE PATHS?
- Creates a very strong surface that can be used for ADA compliant applications
- Creates a permeable surface that helps prevent erosion caused by run-off by slowing the flow of water and aiding penetration into ground soil
- Provides an attractive, natural looking alternative to concrete or asphalt that is particularly desirable for historic sites.
ARE THERE DIFFERENT VERSIONS OF KLINGSTONE PATHS?
Yes, Klingstone Paths comes in an Amber formula and a Klear formula.
While both versions will initially make your stone look wet, the Amber version will lose this glossy appearance within a season or two. Exposure to sunlight causes the exposed coating to return to the natural appearance of the stone. This exposure on the surface doesn’t weaken the bond between the stones below. During this transition period, some amber coloration can be visible. We do not recommend its use on white stone.
Klear has some UV stability that makes the glossy appearance last quite a bit longer than Amber. Klear doesn’t take on any coloration and is therefore suitable for white stones.
IS THERE A TYPE OF AGGREGATE RECOMMENDED FOR USE WITH KLINGSTONE PATHS?
There are certain qualities that we recommend for the aggregate. The stones should be between
¼” and ¾” in size. The aggregate needs to be free of fines and debris. Most importantly, the aggregate must be completely dry!
Both, angular or rounded shaped stones are acceptable. A hard, porous stone is best. Glass beads don’t have enough texture to provide a strong bond between contact points. Recycled asphalt doesn’t have the structural integrity of real stone. Do not use on decomposed granite!
DO CHEMICALS DEGRADE KLINGSTONE PATHS?
Possibly but Klingstone Paths is resistant to leaking gasoline, oil, anti-freeze, transmission fluid, salt and other common ice melting agents.
IS KLINGSTONE PATHS ECO-FRIENDLY?
Yes. Cured Klingstone Paths resin is chemically inert and non-toxic. Both formulas of Klingstone Paths ship as non-hazardous material.
Because water can pass through a properly installed pathway, there is an environmental advantage to helping limit water run-off. Many communities and new construction sites have a limit to the amount of impervious surfaces because of the damage done by excessive run-off of rainwater.
CAN KLINGSTONE PATHS BE USED AROUND TREE ROOTS?
As long as there is enough depth of aggregate on top of the tree roots, the application of Klingstone Paths resin won’t coat the roots themselves. Since Klingstone Paths is permeable, the consolidated aggregate will still allow the tree roots to get the water and air exchange they require to be healthy.
CAN KLINGSTONE PATHS BE USED FOR DRIVEWAYS?
Yes, if certain conditions are met. For a driving surface, we recommend Klingstone Paths only be used on relatively flat surfaces. Klingstone Paths holds up well to compressive forces but lateral force could cause the driveway to shear.
For vehicular traffic, we recommend a higher application rate of one gallon per ten square feet, over a six inch or more layer of gravel. This sixth inch depth should be placed on a strong, compacted base.
WHAT KIND OF MAINTENANCE IS REQUIRED?
Within six weeks of the Klingstone Paths application, a careful inspection of the pathway should be made. Look for any loose aggregate or crumbling edges that could indicate either a missed area or an insufficient application rate of Klingstone Paths resin. This inspection should be repeated on an annual basis. If loose aggregate, or weak areas are found, they should be repaired as soon as possible.
For loose areas with unconsolidated aggregate down to the base, there are two acceptable repair techniques. One is to simply apply more Klingstone Paths resin to the loose aggregate and pack it tightly with a trowel or tamper. The second option is to remove the loose aggregate and place it in an open-top pail, add sufficient Klingstone Paths resin to coat the aggregate, mix thoroughly, then place the mix into the void with a trowel and pack it tightly.
For loose surface aggregate, and to minimize the appearance of spot repairs, use a thick nap paint roller and apply Klingstone Paths resin liberally to the whole surface.
CAN KLINGSTONE PATHS BE USED ON STEEP SLOPES?
We don’t recommend it. The issue with steep slopes is the problem of effective application. Since Klingstone Paths is a liquid resin, gravity will carry much of the resin to the bottom of the slope before it has a chance to cure in place. This results in too little resin on the slope and too much accumulation at the base of the slope.
HOW DO YOU APPLY KLINGSTONE PATHS?
Small jobs can be accomplished with a plastic watering can. Larger jobs benefit from the use of our application pump. Please review the instructional document and “how to” video and reach out to us with any questions.
HOW LONG DOES KLINGSTONE PATHS LAST?
We can’t say for sure. This depends on environmental conditions and the installation practices. The quality and cleanliness of the stone are also factors.
When installed correctly, recoating is advisable after 7 to 10 years.
HOW MUCH DOES KLINGSTONE PATHS COST?
Due to the ever-changing costs of raw materials, the price for Klingstone Paths can change unpredictably. Please call us for current pricing.
WHAT PRESSURE SHOULD I USE TO APPLY KLINGSTONE PATHS WITH A PUMP? HOW BIG OF A COMPRESSOR DO I NEED?
A portable compressor that can generate 8 to 10 CFM and/or has a capacity of 18 gallons or more should be used. When you first turn on the compressor, start at a low pressure of ~50 psi, then steadily increase the pressure until there are thin streams of resin flowing from every hole on the T-head of the applicator wand. Do not exceed pressures of ~90 psi.
WHAT IS THE EFFECT OF KLINGSTONE PATHS ON DRAINAGE?
Klingstone Paths creates a permeable layer of aggregate over your base material. This permeable layer helps to slow run-off on the surface. In most circumstances this helps the water percolate into the soil below. In instances of heavy rain, the more compacted base material may still have trouble handling the volume of water. It’s important to consider how the slope of the base will direct the flow of water in these heavy rain events.
UNDER WHAT CONDITIONS SHOULD KLINGSTONE PATHS NOT BE APPLIED?
- If your aggregate is wet, or even just a little damp
- If your aggregate is too dirty. Dirt and debris should be removed for the best outcome
- If precipitation is expected within 24 hours
- If the temperature is too low. 70°F and rising is ideal. Lower temperatures will slow the cure time and thicken the resin making it more difficult to pump
CAN KLINGSTONE PATHS BE REMOVED?
Yes, it can be broken up with a hammer drill with a chisel bit and disposed of as non-hazardous material. Cutting the path with a circular saw with a masonry blade is a really effective method of cleanly dividing the path into sections.
HOW IS KLINGSTONE PATHS REMOVED FROM OTHER SURFACES?
The same quality that makes Klingstone Paths such an effective binding agent also makes it very difficult to remove from other surfaces.
While Klingstone Paths is still in liquid form, acetone can help remove it from tools. However, porous surfaces are nearly impossible to clean. Surrounding surfaces (like concrete, flagstones, landscape timbers, etc.) should be covered with plastic to avoid staining. Stains on clothing are permanent.
Rubber gloves and eye protection should be worn during the entire duration of the installation. If you get Klingstone Paths resin on your skin, a soap with pumice can help some but ultimately time is the only effective remover.
Once Klingstone Paths is cured, there are no chemical means of removal. Since Klear is UV stable and Amber is not, Amber stains will diminish much quicker than Klear stains.
WHAT SAFETY PRECAUTIONS SHOULD BE TAKEN WHEN INSTALLING KLINGSTONE PATHS?
-Always wear eye protection!
-Wear old clothing that can be permanently stained
-Wear rubber gloves
-If using the application pump, do not exceed 100 psi on the air compressor
-Do not reseal container if it becomes contaminated with moisture
-If using Klingstone Paths Klear, have a NIOSH approved air-purifying respirator equipped with organic vapor cartridges on hand if needed
-Some people have an allergic reaction in the presence of uncured Klingstone Paths Klear resin. Take extra precautions when using in public spaces. Cordon off additional work space.
-Please refer to the SDS for all appropriate health and safety information.
