Tasir®-Epoth is a thixotropic, 3-component patching and repair mortar, based on a combination of epoxy resins and special fillers, designed for use at temperatures between +10 °C and +30 °C.



As a repair and bonding mortar for:

▪ Concrete elements

▪ Hard natural stone

▪ Ceramics, fibre cement

▪ Mortar, Bricks, Masonry

▪ Steel, Iron, Aluminium

▪ Wood

▪ Polyester, Epoxy

▪ Glass

As a repair mortar:

▪ Filling of cavities and voids

▪ Vertical and overhead use

▪ Corners and edges

As an abrasion and impact resistant wearing course:

▪ Joint filling and crack sealing

▪ Joint and crack arris / edge repair



Tasir®-Epoth has the following advantages:

▪ Easy to mix and apply

▪ Very good adhesion to most construction materials

▪ High strength

▪ Thixotropic: Non-sag in vertical and overhead applic- ations

▪ Hardens without shrinkage

▪ Different coloured components (for mixing control)

▪ No primer needed

▪ High initial and ultimate mechanical strength

▪ Good abrasion resistance

▪ Good chemical resistance


Mortar for structural and non-structural repair, tested according to EN 1504-3, provided with the CE-mark











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

Verify the substrate strength (concrete, masonry, nat- ural stone).

The substrate surface (all types) must be clean, dry or mat damp (no standing water) and free from contam- inants such as dirt, oil, grease, existing surface treat- ments and coatings etc.

Steel substrates must be de-rusted similar to Sa 2.5 The substrate must be sound and all loose particles must be removed.


Concrete, mortar, stone, bricks:

Substrates must be sound, dry or mat damp (no stand- ing 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 lait- ance and contaminant free, open textured surface.


Must be cleaned and prepared thoroughly to an ac- ceptable quality i.e. by blast-cleaning and vacuum. Avoid dew point conditions.



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 min- imum. Mix only that quantity which can be used with- in its pot life.


Brush the adhesive well into the substrate. Tasir®-CP be used as primer to improve the bond.

When using a thin layer adhesive, apply the mixed ad- hesive to the prepared surface with a spatula, trowel, notched trowel, (or with hands protected by gloves). When applying as a repair mortar, use some form- work.

When using for bonding metal profiles onto vertical surfaces ,support and press uniformly using props for at least 12 hours, depending on the thickness applied (not more than 5 mm) and the room temperature.

Once hardened check the adhesion by tapping with a hammer.


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


Tasir® resins are formulated to have low creep un- der permanent loading. However due to the creep be- haviour of all polymer materials under load, the long term structural design load must account for creep.

Generally the long term structural design load must be lower than 20–25 % of the failure load.
