Surface Preparation

Remove all loose dirt, oil, dust, grease and other contaminants so as to expose a good, clean, sound surface. For wood floors ensure any loose flooring is tightly nailed down and support is sufficient, that there is no excessive deflection under normal loads. Apply E-Z Flow Primer 100 by using a roller or soft bristle brush on the surface area and allow to dry completely.

Mixing

Mix 4.5L (4.5 qts.) of clean water to 22.7 kg (50 lbs.) of E-Z Flow Concrete Floor Underlayment while mixing. A power mixer is recommended. Let stand for 2 to 3 minutes, remix and add more water if needed to obtain a lump-free flowable mixture. Do not over water; over watering will cause discoloring and bleeding. Do not over mix.

Application

For small installations, mix E-Z Flow powder and water in a five-gallon pail using a 1/2" heavy duty drill with a Turbine Mixer or similar mixing paddle. Place the liquid E-Z Flow Floor Underlayment by pouring directly from the mixing container. If needed, spread material in place with a spreader. E-Z Flow Floor Underlayment will continue to be flowable during the first 15 minutes after mixing. For larger installations, mix 2 bags at a time in a mechanical mixer. E-Z Flow Floor Underlayment can be pumped to installation area. (Contact manufacturer for pump recommendations). E-Z Flow Floor Underlayment can be installed from featheredge to a thickness of 2.5 cm (1") in one operation. For areas of greater thickness, it is recommended to mix the E-Z Flow Floor Underlayment with washed peagravel 6mm (1/4") in size. Mix E-Z Flow Floor Underlayment with water first, then add peagravel. Use 10 kg (22 lbs.) of peagravel per bag. If aggregate is wet, reduce the amount of water to avoid overwatering. If peagravel is not available, then E-Z Flow Floor Underlayment can be applied in a series of 2.5 cm (1") pours until the desired thickness is obtained.

Clean Up

Clean with water as soon as possible after application.

Tips

  • If substrate is moist or wet due to hydrostatic pressure, Stone Mason® Waterproof cement should be applied to seal out moisture prior to application of primer.
  • Porous surfaces will require 2 coats of primer to avoid pinholes, bubbles and improve flow properties of E-Z Flow Underlayment.
  • A 1/4" minimum thickness of material is recommended with the exception of feather edged areas.
