Surface preparation

Concrete Substrates

The surface of the concrete to be repaired shall be sound, clean and uncontaminated.

This preparation shall be such as to leave a sound exposed concrete surface free from dust, loose particles and any deleterious matter. If the concrete surface is defective or has laitance, it must be cut back to a sound base. Excess laitance deposits are best removed by light mechanical scrabbling, grinding or grit/captive blasting followed by vacuum cleaning to remove dust debris.

Any blowholes, chipping or similar surface imperfections shall be repaired using EPOFINISH C, a solvent free epoxy resin repair mortar.  Allow the repair material to harden.

Expansion joints shall be repaired using EPOMORT HS,   a High strength solvent free epoxy mortar.

New concrete or cementitious surfaces should be allowed to cure and have moisture content not exceeding 5%. Old or existing floor should be refurbished mechanically to ensure clear sound substrate.

Priming

The surfaces treated with EPOFLOOR SLE25 should be primed with PRIMER POXY FF, a solvent-free high performance Epoxy primer.

Add the contents of the primer in the Hardener can (Part B) into the Base can (Part A) and mix for two minutes until a homogenous mixture is achieved.

Apply one coat of PRIMER POXY FF onto the dry surface, at a consumption rate of 5-6 m²/Liter.
Allow the primer to dry before proceeding with the self levelling application. Do not apply EPOFLOOR SLE25 while the primer is tacky as this will lead to unsightly marks in the finished surface. Highly Porous substrates may require a second primer coat.

Mixing

EPOFLOOR SLE25 is supplied in two pre-weighed packs (Component A – Base and Component B – Hardener) which are ready for immediate in-situ use. Stir in both components before use.

Transfer the entire contents of component B (Hardener) into the component A (Base) can and mix with low speed drill and paddle (200 – 300 rpm) for 2 – 3 minutes till obtaining a mix with uniform consistency. Scrape the sides and bottom of the can during mixing to ensure homogeneity.

Application

Pour the mixed material onto the primed surface in pools or as a long strip. Using a trowel, pin screed, or notched trowel, spread EPOFLOOR SLE25 to the required thickness. To release entrapped air and assist with the smoothing operation, roll the material within 5 minutes after it is leveled, using spiked roller.

Allow to cure for minimum 18 hours at 25°C for light traffic.

Cleaning

Tools and equipment should be cleaned with SOLVENTE 10 immediately after use. Hardened material should be removed mechanically.

Spillages should be absorbed with sand or sawdust and disposed of in accordance with local regulations.

Recommendations

• EPOFLOOR SLE25 should not be applied at temperatures below +5°C and above +35°C.
• EPOFLOOR SLE25 should not be applied to asphalt, weak or friable concrete, PVC tiles or sheet substrates.
• EPOFLOOR SLE25 should not be applied if the surface relative humidity is more than 75%.
• All existing expansion or movement joints should be followed through the new floor surface.
• It is strongly recommended to apply EPOFLOOR SLE25 by specialist contractor or experienced applicator who must follow the procedures laid down in the product Method Application.
