Sikafloor® Pronto 1817 PC

Always refer to the best-before date of the individual packaging

For best performance, keep material stored indoors in a cool (below 80°F), dry environment, protected from damage and moisture, out of direct sunlight. Do not store near food, open flame or ignition source. Read and understand all product labels and Safety Data Sheets prior to use.

All coverage rates are approximate. Coverage rates will vary with the desired texture and porosity of substrate along with application/extension of Sikafloor® Pronto 1817 PC. Please refer to the Sikafloor® Pronto Mixing Chart for further information.

HOW TO APPLY  
Every Sikafloor® Pronto flooring system is a multiple component system that utilizes a methyl-methacrylate (MMA) resin. It is critical that the Material Safety Data Sheet for every component of the system is read and understood. MMA resins are flammable liquids in their uncured state. Smoking, open flames, or sparks should not be permitted while handling the product. Explosion safe ventilation must be used during the application to minimize vapor collection in the installation area and to improve overall air quality for the crew. All foodstuffs must be removed during installation of the flooring system. Sikafloor® Pronto systems are installed by approved contracting firms. The following is only a summary of the installation techniques used by Sikafloor® Pronto approved contractors.

SURFACE PREPARATION

1. Floors must be structurally sound and fully cured a minimum of 28 days. Conduct quantitative moisture testing in accordance with ASTM F2659-10 utilizing Tramex type impedance moisture meter. Please contact Sika Flooring Technical Support if the Tramex reading is over 4%.

2. Use a commercial degreaser to clean floors of oil, grease, and other bond-inhibiting materials.

3. Remove curing and parting compounds and other surface hardeners and floor coatings in accordance with manufacturer's instructions.

4. Mechanical surface profiling is the method of surface preparation for both new and existing floors. Mechanically profile the floor to CSP-4 or greater as described by the International Concrete Repair Institute. Do not use acid etching for surface preparation. Do not use any method that will fracture the concrete.

5. Bond tests should be performed once a small area has been mechanically profiled, so any adjustments can be made to the surface preparation process. Bond tests should be repeated every 500-1,000 ft² (46.5 - 93 m²). Please refer to Bond Test Instruction Guide for further information.

6. Cracks wider than 1/16" (1.6 mm) should be "chased out" and opened during surface preparation. Any existing joints should be treated according to project specifications. Please refer to Joint Repair Guide for further information.

7. Areas around drains and other floor fixtures need to be ground and/or chipped to a depth between 1/2" - 3/4" (12.7 - 19 mm) and tapered back 3" - 6" (7.6 - 15.2 cm) away from drain (Refer to Sikafloor® Pronto Detail Drawing CB-27.3).

8. Termination points should be saw cut to a depth of 1/4" (6.4 mm) and tapered back (Refer to Sikafloor® Pronto Detail Drawing CB-27.2).

SIKAFLOOR®-41 P PRONTO PRIMER
Measure resin and Sikafloor®-103 IN Pronto into pail and add proper amount of Sikafloor®-100 HD Pronto. Mix with drill mixer for 15-30 seconds or until the Sikafloor®-100 HD Pronto is completely dissolved. Please contact Sika Flooring Technical Support if Sikafloor®-51 P Pronto Primer is required.

Every Sikafloor® Pronto flooring system is a multiple component system that utilizes a methyl-methacrylate (MMA) resin. It is critical that the instructions listed in the Safety Data Sheet and on the product label for every component of the system be read, understood and followed. MMA resins are flammable liquids in their uncured state. Smoking, open flames or sparks should not be permitted during the handling of the product. Explosion safe ventilation must be used during the application to minimize vapor collection in the installation area and to improve overall air quality for the crew. All foodstuffs must be removed during installation of the flooring system.

PRIMER
Apply the properly mixed Sikafloor®-41 P Pronto resin to the properly repaired concrete or properly prepared aged coating at approximately 100 ft² (9.3 m²) per gallon. Allow primer to cure tack-free to an even, satin-like gloss. Re-prime any dry spots.

POLYMER CONCRETE

Please refer to polymer concrete mixing and extension guideline on the back of the Sikafloor® Pronto Mixing Chart. Measure Sikafloor®-17 RS Pronto Part A into a 5 gallon pail. Add 1 bag of Sikafloor®-17 RS Pronto Part B powder and mix using a spiral mixing blade for 30 - 45 seconds or until a homogenous mixture is obtained. 

NOTE: If you need to extend the batch, add the clean, dry, approved aggregate in the proper amount to the Part A resin prior to adding the Part B powder.

Sikafloor® Pronto 1817 PC must be re-primed prior to installing a Sikafloor® Pronto MMA system over it.

DRYING TIME
All components of the Sikafloor® Pronto 1817 PC flooring system fully cure within one hour when properly installed.

Clean tools as needed with Sikafloor®-100 CLN Pronto. Collect and dispose of all site wastes according to appropriate regulations.
