Like the dishes in your sink, hot water "melts" grease and grime; cold water only pushes it around. On the other hand, if you're simply blasting away sand, caked-on mud, or even stripping paint, a cold water pressure washer will work just fine.

PSI (Pounds per Square Inch) refers to the amount of cleaning pressure the machine can produce. GPM (Gallons per Minute) is the amount of water that is coming from the machine.

In our opinion, both are important, but GPM is underrated. Too much pressure can ruin surfaces, so it must be used in the right places, usually with the right chemicals and cleansers to be most effective.  High GPM machines can efficiently move the most soil and dirt and allow larger areas to be cleaned economically.

If your parking lot is concrete, you can pressure wash it to clean it without necessarily stripping it.  Striping will be needed when the paint is chipping or fading.  Like most, if your lot is asphalt, you will not want to pressure wash it because it will dig up the asphalt.  In this case, you can clean it with low pressure and cleansers/degreasers.  Again, repairs to the asphalt and striping might be needed afterward.  Aside from making your parking lot look great, sealcoating is the most essential maintenance element of your asphalt parking lot. Sealcoat is applied over the asphalt to help protect against the daily destructive elements. Good line striping creates direction and provides a vital safety factor for your parking lot.

While asphalt speed bumps cost more to install, they're more resistant to damage than many plastic or rubber models.

The bottom of your sign must be placed at a minimum of sixty inches above the ground to ensure visibility. Signs for van spaces should be clearly marked "van accessible." Any further clarifications can be found in the ADA National Network's Factsheet on Accessible Parking Lot Signs.

The international symbol of accessibility should be posted on all accessible parking spaces marking the reserved spot.  ADA handicap parking signs (commonly known as Access Signs) posted must be visible from the drivers' seat of the vehicle and located right in view of parking spaces.

Yes, wheel stops can be added to any existing parking lot. Typical installation methods include epoxy, mechanical pinning, and gravity weighted. Wheel stops epoxied to the parking lot may be knocked loose and require routine inspections.

Typically, sealcoating is recommended every three years to provide adequate pavement protection as well as attractive curb appeal for your commercial property or home.

Typically, it's an excellent idea to restripe your parking lot every 18 to 24 months, depending on your location and climate, and you want the stripes and spaces in the lot to be clear and bright.

Sealcoating is not designed to be an asphalt crack filler. It is made to seal the surface and protect it from the elements such as UV light, salts, and oils. It is not flexible enough to fill a crack without re-cracking, and it does not have adhesion quality's that Asphalt Crack Filler has.

Curb striping or painting is used to clarify parking and other curb use rules. The color painted on curbs means: White (or no color): Parking allowed, unless restricted or limited by signs. Blue: Parking for the disabled only. Red: Fire/First Responders only.

This is based on the property owner's preference; either yellow or white can be used. A good time to change colors is when the asphalt is being seal coated.

The parking lines' configuration is usually dictated by local code or by the building engineer. Within those limits, we can scarify away old lines and "move" them.

Paint should be applied using an airless striping machine at a minimum of 13 mil thickness to ensure high-quality lot marking.

We ask that you please allow at least 48 hours of drying time, and out of those 48 hours, 12 hours be in the sunlight. Drying time may vary from day to day, so we ask that you use your best judgment. IF IT LOOKS WET, IT IS WET. You may walk on your asphalt as soon as it looks dry.

Typical drying time is 30 minutes; however, traffic should remain off the lot for at least one full hour.

Sealcoating is best applied when pavement and ambient temperatures are at least 50 degrees Fahrenheit. However, the temperature should not be any higher than 85 degrees Fahrenheit. The pavement should not be wet.

Line striping is best applied when pavement and ambient temperatures are at least 45 degrees Fahrenheit. The pavement must not be wet.

It is best to wait at least 24 hours before driving on the new surface. We often advise that you wait longer during hot weather. Following installation, be sure to follow a regular preventative maintenance plan, including sealcoating and crack filling, to keep your asphalt looking its best.

Typically, sealcoating is recommended every three years to provide adequate pavement protection as well as attractive curb appeal for your commercial property or home. New patches don't have to be seal coated until the next time you're going to be seal coating the whole lot.

For most concrete structures, the curing period at temperatures above 40º F should be a minimum of 7 days or until 70% of the specified compressive or flexural strength is attained. The period can be reduced to 3 days if high early strength concrete is used and the temperature is above 50º F. Fresh asphalt is laid at about 300º F, so it cools rapidly, even in hot ambient temperatures.

If the humidity is above 90%, sealer or paint should not be applied due to air saturation. Temperature: Temperature refers to both ambient and surface temperatures. ... The higher the temperature, the faster evaporation, and thus dry time.

The truth is that you should be using a hot mix to repair your potholes effectively. However, cold patches are usually used as a temporary fix until you can have the pothole repaired adequately. Hot-mix repairs are a much bigger process and may take time to perform.
