SUBSTRATE QUALITY / PRE-TREATMENT

Concrete

The concrete shall be free from dust, loose material, surface contamination and materials which reduce bond or prevent suction or wetting by repair materials.


Steel reinforcement

Rust, scale, mortar, concrete, dust and other loose and deleterious material which reduces bond or contrib- utes to corrosion shall be removed to a minimum standard of SA2½.


Reference should also be made to BS EN1504-10:2003 for specific requirements.

Substrate Preparation/Bonding Primer/Reinforce- ment Coating

Concrete:

Delaminated, weak, damaged and deteriorated con- crete and where necessary sound concrete shall be re- moved by suitable mechanical or very high pressure waterblasting [up to 110 mPa (16500 psi)] techniques. Tying wire fragments, nails and other metal debris em- bedded in the concrete should be removed where pos- sible.

The edges where concrete is removed should be cut at a minimum angle of 90o to avoid undercutting and a maximum angle of 135o to reduce the possibility of de- bonding with the top surface of the adjacent sound concrete and should be roughened sufficiently to provide a mechanical key between the original materi- al and Tasir®-MT05.

Ensure sufficient concrete is removed from around re- inforcement to allow coating and compaction of the repair material.


Steel reinforcement:

Surfaces should be prepared using abrasive blast cleaning techniques or high pressure waterblasting [up to 60 mPa (9000 psi)] techniques.

Where exposed reinforcement is contaminated with chloride or other material which may cause corrosion, the reinforcement shall be cleaned by low pressure waterblasting [up to 18 mPa (2700 psi)].


Bonding primer:

On a well prepared and roughened substrate a bond- ing primer is generally not required.

When a bonding primer is not required pre-wet the surface. The surface should not be allowed to dry be- fore application of the concrete repair mortar. The sur- face should achieve a dark matt appearance without glistening and surface pores and pits should not con-tain water.

When a bonding primer is necessary apply Tasir®-MT01 (Refer to the relevant Product Data Sheet).

Site adhesion values - Structural Repair 1.2-1.5 mPa Non Structural repairs minimum value 0.7 mPa


Reinforcement coating:

Where a reinforcement coating is required as a barrier apply to the whole exposed circumference two coats of Tasir®-MT01 or Tasir®- EpoCemment  if chlorides are present.(Refer to the relevant Product Data Sheet).

Reference should also be made to BS EN1504-10:2003 for specific requirements.


MIXING

Tasir®-MT05 can be mixed with a slow speed (< 500 rpm) electric drill mixer.

In small quantities only, product can also be mixed by hand.

Pour the water in the correct proportion into a suit- able mixing container. While stirring slowly, add the powder to the water. Mix thoroughly for at least 3 minutes to the required consistency.


APPLICATION

Hand Applied

If a bonding primer has been used apply repair mortar “wet on wet”. The repair mortar shall be worked into the prepared pre-wetted substrate between the min- imum and maximum layer thicknesses and shall be compacted without inclusion of entrapped air pockets using a trowel or gloved hand.

Where layers are to be built up to prevent sagging or slumping, each layer should be allowed to stiffen be- fore applying subsequent layers “wet on wet”. When layers cannot be applied “wet on wet”, or if more than 24 hours between layers apply a bonding primer of Tasir®-MT01 and apply repair mortar “wet on wet”.

Finishing should be done to the required surface tex- ture as soon as mortar has started to stiffen.

Reference shall be made to BS EN1504-10:2003 for specific requirements.


CURING TREATMENT

It is essential to cure the repair mortar immediately after application for a minimum of 3 days to ensure full cement hydration and to minimise cracking. Use polythene sheeting taped down at the edges or other approved method.

Curing compounds shall not be used when they ad- versely affect subsequently applied products and sys- tems.

Reference shall also be made to BS EN1504-10:2003 for specific requirements.


CLEANING OF TOOLS

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


LIMITATIONS

▪ Refer to recommendations provided in BS EN 1504- 10.

▪ Avoid application in direct sun and/or strong wind and/or rain.

▪ Do not add water over recommended dosage.

▪ Apply only to sound, prepared substrates.

▪ Do not add additional water during the surface finish- ing as this will cause discoloration and cracking.

▪ Protect freshly applied material from freezing.
