Sikafloor®-958 PG should be used full strength with out dilution. .
Dilution Rates
For second pass or maintenance applications can be diluted 1:1 with potable water.
Mixing
If diluted, mix until uniform.
Coverage
Coverage will depend upon method of application, surface porosity, age, moisture, absorption characteristics and the texture of the concrete. The application of two thin coats prior to burnishing is recommended.
Spread rate on flat finished concrete that has been ground, densified, and roughly polished with a 400 grit abrasive disk, is typically 1200-1500 ft2/gal (36.7 - 49.0 m2/L). Slabs ground to expose hard non absorptive aggregates will take less material. For all uses and applications, spread or scrub puddles of excess material into surfaces before it is allowed to dry. Puddled material allowed to dry can form unsightly salts that are difficult to polish.
Equipment
Apply Sikafloor®-958 PG by low pressure pump-spray application, followed by thorough spreading and distribution with a microfiber mop or floor wax applicator to work material into substrate pores.
High-speed burnishing equipment will be required along with coarse through super fine diamond impregnated polishing disks. Disks beginning with 400 grit, and progressively finer will be needed. Typical sequences of disks used include 400, 800, 1200, and 3000 grit. Final grit selection will determine final gloss.
Always wear protective clothing and personal protection equipment proper for the method of application and burnishing.
Spray Aplicaters Guidelines
Mask all areas not to be coated to safeguard against splashes, overspray, and runoff from application. Wear all required safety equipment. Take care not to allow tape adhesive to interfere with surfaces to be treated. Surfaces wet with material will be slippery until dry.
Distribute product with a pump garden sprayer to fully saturate the surface. Spread material with flat microfiber pad or floor wax applicator. If too much material has been applied, and it is puddled after 30 minutes, dilution and removal with a wet vacuum is recommended.
Recoat Time
Allow the material to dry to touch, and apply a second coat.
Take care not to create lap marks as they are difficult to remove once the product has dried.
When the second application is dry, high-speed burnishing and polishing with progressively finer grit abrasive pads can begin.
Dry times
will depend upon weather conditions. At 70°F (21°C) and 50% relative humidity surfaces should be dry and able to be polished in 1 hour. Sikafloor®-958 PG has a self-crosslinking component, best results will be achieved if the final high-gloss polishing is performed after an overnight dry.
