Coverage
4.5 mixed gallons (approximate coverage) at: 16 mils = 450 ft2 (42 m2)
Sikafloor®-260 ESD should be applied at 15 - 18 mils.
Product will lose ESD properties if applied at excessive thickness. Do not exceed the recommended thickness.
MIXING
Mixing Ratio: 2 : 1 by volume (Mix full unit only)
Premix each component separately with a jiffy type blade with a variable speed drill. Use a long margin tool to ensure contents are evenly distributed scraping the sides, corners and bottom of the pail of both components. Add the premixed component B to the pigmented component A and mix for 3 minutes at a moderate speed (300rpm) with a jiffy type mixing blade and a variable speed drill, scraping the container sides, bottom, and corners with a flat or straight edge trowel at least once to ensure complete mixing.
Do not hand mix Sikafloor materials. Mechanically mix only.
Do not thin this product. Addition of thinners (e.g. water, solvent, etc.) will slow cure and reduce ultimate properties of this product. Use of thinners will void any applicable Sika warranty. Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature. Sikafloor®-260 ESD must be placed and distributed on the application surface immediately after mixing.
APPLICATION
The Sikafloor®-260 ESD 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 to 1/8 inch (1.6 - 3.2 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®-260 ESD 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 5 gallon (18.9 liter) pail of the mixed Sikafloor®-260 ESD 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®-260 ESD 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®-260 ESD squeegee applied material. One person can roll apply a 15 to 20 ft (4.6 - 6.1m) wide section. Do this as quickly as possible.
3. Pour another line of Sikafloor®-260 ESD 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®-260 ESD at the junction of the previously rolled and freshly applied Sikafloor®-260 ESD.
4.Follow these procedures until the section is completed. If the work must stop for any reason, use a tapeline as a breaking point.
