Sika Sikafloor 125 Level Latex

Sika Sikafloor®-125 Level Latex is a ready to use (just add water) latex-modified smoothing and levelling compound for advanced flexibility and resilience. It is suitable for smoothing and levelling uneven rigid internal floors prior to applying final wearing coverings.

Best Uses

Sika Sikafloor 125 Level Latex is an ideal self levelling compound for use with Sika floor systems. Suitable for the leveling / smoothing of concrete, sand/cement screeds (not anhydrite), for under quarry tiles, terrazzo, and ceramic tiles. Also suitable for use under underfloor heating applications beneath heating cables/pipes or on top of heated screeds.

• Self-smoothing and highly fluid
• Easy to place by pump or manual application
• Low shrinkage
• Maintains good workability and joint healing throughout its pot life
• Fast setting and drying
• Good surface appearance and hardness
• Excellent freeze-thaw salt resistance
• Protein and formaldehyde free
• Underfloor heating applications beneath heating cables/pipes or on top of heated screeds

Sikafloor®-125 Level Latex can be applied from a maximum thickness of 6 mm (25 mm when filled) down to a featheredge.

System

Priming: Sika SikaBond® PVA+ (1 part PVA to 4 parts clean water)
Levelling: Apply to the required thickness up to 6 mm unfilled or 25 mm with added sharp sand

Application

SUBSTRATE QUALITY / PRE-TREATMENT

• Normal Absorbent Concrete/Screed: These substrates do not normally require priming. Damp down floor with clean water without leaving puddles and allow to surface dry. If water is absorbed immediately into substrate, treat as porous surface.
  Porous Concrete/Screed: Seal surface with Sika SikaBond® PVA+ (1 part PVA to 4 parts clean water) ensuring surface is well coated, then allow to dry. For highly porous substrates it may be necessary to apply more than one coat to prevent pinholes and cracking/debonding of Sikafloor®-125 Level Latex.
• Non Porous/Dense Substrates (quarry/ceramic tiles, terrazzo and smooth concrete etc): Mechanically roughen surfaces by grinding or scarifying to provide a mechanical key.Alternatively, apply a bonding coat of undiluted Sika-Bond® PVA+ and allow to become tacky before applying levelling compound.

MIXING
Mix thoroughly for a minimum of 3 minutes with an electric stirrer (< 500 rpm). Unfilled (up to 6 mm thick) Mix Sikafloor®-125 Level Latex with clean water only. Slowly add 5 parts powder to 1 part water (25 kg powder will require 5 L / 5 kg of water). Mix in a suitable clean container using a mechanical mixer with a spiral mixing paddle at slow speed until fully mixed and a smooth consistency achieved. Occasionally during hot weather the product may require remixing during the 15 - 20 minute pot life to reactivate the self-levelling characteristics. DO NOT add extra water. Discard any unused material after 20 minutes from initial mixing.

Filled (up to 25 mm thick): Mix Sikafloor®-125 Level Latex at a 1:1 ratio with sharp sand then with clean water only. Slowly add 10 parts powder to 1 part water (25 kg powder plus 25 kg sharp sand will require 5 L / 5 kg of water). Mix in a suitable clean container using a mechanical mixer with a spiral mixing paddle at slow speed until fully mixed and a smooth consistency achieved. Occasionally during hot weather the product may require remixing during the 15 - 20 minute pot life to reactivate the self-levelling characteristics. DO NOT add extra water. Discard any unused material after 20 minutes from initial mixing.

Sikafloor®-125 Level Latex can be applied from a maximum thickness of 6 mm (25 mm when filled) down to a featheredge. Pour the mixed product onto the floor and spread evenly with a steel trowel to form a thin, tight scrape coat within working time. Immediately add further quantities of mixed product to give the desired thickness. Trowel marks should flow out of the product to leave a smooth finish (if not, trowel again when the surface is still damp but firm to the touch). If required use a spiked roller, within working time, in unfilled product to provide a more uniform surface appearance.
