Consumption

Coverage

4.50 mixed gallons (approximate coverage) at: 16 mils = 450 ft2 (42 m2)
Sikafloor®-264 ECF should be applied at 15 - 18 mils.
Product will lose ESD properties if applied at excessive thickness. Do not exceed the recommended thickness.
Application steps

MIXING

Mix full units only
Premix each component separately. Stir Component A container with a long margin tool to ensure contents are evenly distributed scraping the sides, corners and bottom of the pail. A Jiffy-type mixing paddle with a variable speed mixing drill is used to premix the Component A, then add the Component B to the pigmented Component A and mix for 3 minutes at a moderate speed (300rpm), scraping the container sides, bottom, and corners with a flat or straight edge trowel at least once to ensure complete mixing. Do not strain material. Straining will remove conductive element.
Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature. Sikafloor 264 ECF must be placed and distributed on the application surface immediately after mixing.

 

APPLICATION

The Sikafloor 264 ECF should be applied with a notched squeegee over a smooth primed substrate. The notched squeegee should be 18 to 24 inches (45.6 to 60.1 cm) long with 1/16 (1.6 mm) notches at 1/4 inch (6.4 mm) intervals. This type of squeegee will apply sufficient material to achieve 15 - 18 wet mils when back rolled. Back rolling is typically done with a 9 inch (22.8 cm) or 18 in (45.6 cm) wide, 3/8 inch (9.5 mm) short nap, solvent resistant roller cover. Back roll the Sikafloor 264 ECF to level the material applied. Over-rolling and late back rolling may cause bubbling and leave roller marks. Divide the floor into sections that can be completed without stopping. When ending a section, tape it off to form a clean edge for an adjacent section.

The recommended application procedures are:
1.Take one 4.5 gallon pail of the mixed Sikafloor 264 ECF and start at one end of the section to be coated. Trim the walls and/or obstructions in the immediate area where the coating will be applied. Pour the Sikafloor 264 ECF in a line approximately 1 ft (0.3 m) from the wall or starting line along the entire width of the section to be coated.

 
2. The person using the squeegee can then make one pass along the wall or starting line, turn and come back making a second pass adjacent to the first pass. Next, use the rollers to level the Sikafloor 264 ECF squeegee applied material. One person can roll apply a 15 to 20 ft (4.6 - 6.1 m) wide section. Do this as quickly as possible.
3. Pour another line of Sikafloor 264 ECF approximately 1 ft (0.3 m) from the rolled area and repeat step 2. The rolling personnel should make sure they are not leaving puddles or thick sections of Sikafloor 264 ECF at the junction of the previously rolled and freshly applied Sikafloor 264 ECF
4.Follow these procedures until the section is completed. If the work must stop for any reason, use a tapeline as a breaking point.
