Resistant to many chemicals. Contact Sika Technical Services for additional information.

Short-term moist/wet heat* up to +80 °C where exposure is only temporary (steam cleaning etc.)
* No simultaneous chemical and mechanical exposure and only in combination with Sikafloor®-13 / -16 / -17 Pronto as a broadcast system with ~3 - 4 mm thickness.

Part A: Part C: Pigment = 12,5 : 25 : 1 parts by weight (pbw)

The amount of hardener required to be added to 12,5 kg of Part A: (Sikafloor® Pronto Resin) is dependent on the substrate temperature.

The hardener powder can also be ordered under the product name „Perkadox CH 50 X“ by Akzo Nobel, www.akzonobel.com, “Interox BP-50 FT” by Degussa, www.degussa.com or “BP 50 W+” by Pergan GmbH, www.pergan.com.

Beware of condensation.
The substrate and uncured applied floor material must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the floor finish.

The following test methods can be used: Sika®-Tramex meter, CM-measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet).

Select the most appropriate equipment required for the project:

Substrate preparation

• Abrasive blasting cleaning equipment
• Planing machine
• Scarifying machine
• High pressure water blasting equipment

For other types of preparation equipment, contact Sika Technical Services

Mixing

• Electric single or double paddle mixer (300–400 rpm)
• Electric single or double paddle mixer (300–400 rpm) with spark free induction motor for indoor mixing
• Scraper
• Clean mixing containers

For other types of mixing equipment, contact Sika Technical Services

Application

• Mixed material carrier
• Trowels including serrated
• Spiked roller
• Squeegee
• Fleece rollers
• Flat spatula

Prior to mixing all parts, mix separately Part A (resin) thoroughly using an electric single paddle mixer or other similar equipment. Add Sikafloor® Pronto Filler and if required, Sika®-Pronto Pigment to Part A and mix these parts for at least 1,0 minute until a uniform mix has been achieved. If the coloured pigment has been added, mixing must ensure a consistent colour has been achieved. When Parts A, filler and pigment have been mixed, add Part B (hardener) and mix for at least another 1,0 minute, until a uniform mix has been achieved. To ensure thorough mixing, pour materials into another container and mix again to achieve a smooth consistent mix. Excessive mixing must be avoided to minimise air entrainment. During the final mixing stage, scrape down the sides and bottom of the mixing container with a flat or straight edge trowel at least once to ensure complete mixing. Mix full units only. Mixing time for Part A + Filler + Pigment + Part B = ~3,0 minutes.

For ease of handling and mixing, 25 kg units may be divided (2 × 12,5 kg) (refer to Mixing table). Always weigh each product part.

Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

Prior to application, confirm substrate moisture content, relative air humidity, dew point, substrate, air and product temperatures. If moisture content > 4% parts by weight, Sikafloor® EpoCem® may be applied as a Temporary Moisture Barrier (T.M.B.) system. For external applications, apply on a falling temperature. If applied during rising temperatures “pin holing” may occur from rising air.

Levelling
Rough surfaces must be levelled first using Sikafloor®-32 Pronto (with or without Sika® Pronto Pigment) or using Sikadur®-12 Pronto levelling mortar. Apply by squeegee / trowel to the required thickness. Confirm waiting /overcoating time has been achieved before applying subsequent products. Refer to individual Product Data Sheet.

Reinforced layer
Pour mixed Part A: Sikafloor® Pronto Resin and Part B: Sikafloor® Pronto Hardener onto prepared levelled substrate and spread evenly using a serrated trowel. Spike roller immediately in one direction to ensure an even thickness and to remove any entrapped air. Roll out the Sika® Reemat Premium (weight ~225g/m²) reinforcement fleece into the wet resin. Overlap all the reinforcement fleece joints by a minimum 50 mm. Remove any entrapped air bubbles using a lamb's wool fleece roller. Apply wet on wet, an encapsulation layer of Part A: Sikafloor® Pronto Resin and Part B: Sikafloor® Pronto Hardener, filled with Sikafloor®-Pronto Filler. Use a lamb's wool fleece roller or flat spatula to ensure full saturation of the reinforcement fleece with the mixed resin.

Slip-resistant broadcast layer

Pour mixed Sikafloor®-32 Pronto onto prepared substrate and spread evenly using a serrated trowel to the required thickness.
Spike roller immediately in two directions at right angles to each other to aid air release and ensure an even thickness. Immediately broadcast with quartz sand or silicon carbide, at first lightly and then to excess to produce an even distribution surface profile. Allow Sikafloor®-32 Pronto to initially cure and remove all loose sand by vacuum extraction equipment. A multi coloured surface can be obtained by broadcasting with coloured-quartz.

Seal / Top coat

After waiting the required overcoating time / curing, pour the mixed Sikafloor®-18 Pronto onto the slip resistant broadcast layer and spread evenly using a squeegee or short-pile nylon roller at the required consumption rate to completely encapsulate the sand. Then using a short-piled roller, back roller in two directions at right angles to each other. A seamless finish can be achieved if a ‘wet’ edge is maintained during application.

Self - smoothing wearing layer
Pour mixed Sikafloor®-32 Pronto onto prepared substrate and spread evenly using a suitable serrated trowel to the required thickness.
Spike roller immediately in two directions at right angles to each other to remove trowel marks, aid air release, ensure an even thickness and obtain the required surface finish.  A seamless finish can be achieved if a ‘wet’ edge is maintained during application.

Clean all tools and application equipment with Thinner C immediately after use. Hardened material can only be removed mechanically.
