Sikadur®-41 IN

3-part thixotropic epoxy patching mortar

Sikadur®-41 IN is a solvent-free, 3 component thixotropic mortar based on a combination of epoxy resins and selected quartz aggregates. After mixing it becomes an easy to use multipurpose repair and adhesive mortar.

  • Easy to mix and apply
  • Very good adhesion to most construction materials
  • High strength mortar
  • Thixotropic: non-sag in vertical and overhead applications
  • Hardens without shrinkage
  • Different coloured components (for mixing control)
  • No primer needed
  • High initial and ultimate mechanical strength
  • Good abrasion resistance

Usage

Sikadur®-41 IN can be used in a number of varying applications :
  • As bonding mortar on stone, concrete, mortar, plaster work, etc.
  • For vertical and overhead filling of cavities
  • For damaged stair-nosings and spalled concrete
  • As abrasion resistant protective layer
  • Suitable for bearing pad for bridges and heavy machinery

Application

Application Information

Mixing Ratio

Part A : Part B : Part C = 2 : 1 : 3 (by weight)

Layer Thickness

30mm max.

When using multiple units, one after the other. Do not mix the following unit until the previous one has been used in order to avoid a reduction in handling time

Sag Flow

Non-sag upto 20mm layer thickness on vertical surface

(ASTM D 2730)

Ambient Air Temperature

+10°C min. / +40°C max.

Substrate Temperature

+10°C min. / +40°C max.

Substrate Moisture Content

When applied to mat moisture concrete, brush the adhesive well into substrate.

Pot Life

~30 minutes (100 g mass at +30°C)

(FIP 5.1)

The potlife begins when the resin and hardener are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the potlife. To obtain longer workability at high temperatures, the mixed adhesive may be divided into portions. Another method is to chill parts A+B and C before mixing them (not below +5°C).

Application steps

SUBSTRATE QUALITY

Mortar and concrete must be older than 28 days (depends on minimal requirement of strengths).

Verify the substrate strength (concrete, masonry, natural stone).

The substrate surface of concrete, mortar, rendering stone surfaces must be sound, clean, dry or mat damp (no standing water) and free from contaminants such as dirt, oil, grease, existing surface treatments and coatings, dust and other surface contaminants etc.

SUBSTRATE PREPARATION

Substrate preparation work may be done by sand-blasting or any other mechanical means.

Concrete, mortar, stone, bricks:

Substrates must be sound, dry or mat damp (no standing water) , clean and free from laitance, ice, grease, oils, old surface treatments or coatings and all loose or friable particles must be removed to achieve a laitance and contaminant free, open textured surface.

 

Non-absorbent surfaces:

Substrates must be sound, clean and de-rusted as required.

 

PRIMING

  

Sikadur®-41 IN does not generally require a primer. However, on damp or wet surfaces (no standing water), use Sikadur®-31 IN as primer for horizontal, vertical and overhead application. Coat the surface completely with the primer using a stiff brush. Work the primer well into the surfaces. Apply Sikadur®-41 IN while the primer is still tacky.

MIXING

Pre-batched units:
Mix components A+B together for at least 3 minutes with a mixing spindle attached to a slow speed electric drill (max. 300 rpm) until the material becomes smooth in consistency and a uniform grey colour. Then add part C and continue until mixture is homogeneous. Avoid aeration while mixing. Then, pour the whole mix into a clean container and stir again for approx. 1 more minute at low speed to keep air entrapment at a minimum. Mix only that quantity which can be used with in its pot life.

CLEANING OF TOOLS

Clean all tools and application equipment with Sika® Colma Cleaner immediately after use. Hardened / cured material can only be mechanically removed.
