Sika Sikafloor 10 Pronto N

Sika Sikafloor 10 Pronto N is a two part, solvent free, medium viscosity, methacrylic resin primer.

Best Uses

Sikafloor 10 Pronto N is best used to ensure good adhesion for Sikafloor® Pronto Modular Systems on absorbent and non-absorbent substrates. It is very fast curing - even at low temperatures, and provides improved adhesion on very critical substrates.

Suitable for use on the following surfaces:

• Concrete
• Cementitious screeds
• Asphalt
• Glazed ceramic tiles
• Stainless steel
• Galvanised steel
• Mild steel

Please note: Sikafloor®-10 Pronto N may only be used by experienced professionals.

Substrate Quality / Pre-Treatment

• The concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm2) with a minimum pull off strength of 1.5 N/mm2.
• The substrate must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc.
• Concrete substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and achieve an open textured surface.
• Weak concrete must be removed and surface defects such as blow holes and voids must be fully exposed.
• Repairs to the substrate, filling of blowholes/voids and surface levelling must be carried out using appropriate products from the Sikafloor®, Sikadur® and Sikagard® range of materials.
• All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush or vacuum. 

Application

Confirm substrate moisture content, relative air humidity and dew point prior to application. For external applications, apply on a falling temperature. If applied during rising temperatures “pin holing” may occur from rising air.

Mixing

Mix part A thoroughly. Then add Sika®-Pronto Hardener in the correct quantity and mix for a further 1 minute. Over mixing must be avoided to minimize air entrainment. For ease of handling, units may be split (refer to Mixing Table). Always weigh out components.

Mixing Tools
For indoor work, spark free mixing equipment must be used (explosion-proof)! Sikafloor®-10 Pronto N must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment.

Priming

Normal non-porous surfaces: Apply one coat of Sikafloor®-10 Pronto N. Make sure that a continuous, pore free coat covers the substrate, i.e. minimum 0.4 kg/mm². If in doubt, apply another priming coat.

Absorbent surfaces: Apply two coats wet on wet of Sikafloor®-10 Pronto N until saturation of the substrate is achieved. For waiting time before overcoating see table “Waiting Time / Overcoatability”. Apply Sikafloor®-10 Pronto N using a “non-fuzzing”, short-pile nylon roller. The freshly applied priming coat can be blinded slightly with quartz sand 0.6 - 1.2 mm, consumption approx. 0.2 - 0.5 kg/m². If the subsequent layer is Sikafloor ®-32 Pronto applied as a scratch coat, lightly blinding is mandatory.

Difficult surfaces: The application of a trial area is mandatory, when using Sikafloor®-10 Pronto N as a primer for difficult surfaces, such as tiles, asphalt, steel etc.
