Estobond P

Acrylic Emulsion Bonding Agent



Estobond P is a single component white, milky emulsion based upon modified acrylic type resins.

It is formulated as a bonding agent for concrete repair and cement modifier for plastering purposes.



Estobond P is a bonding agent for Estopatch concrete repair system. It may also use as bonding agent for concrete and cement/ sand mortar.



  • Single
  • Long open times, designed for ease of use under site condition.
  • Excellent bond strength between polymers modified mortars and
  • Cost effective and economical in use
  • Can be used as curing membranes for Estopatch material.
  • Water resistant, can be used internally and externally with complete


Standards Compliance

  • ASTM C 190
  • BS 6319
  • BS 5350:Part C15:1990


Physical Properties


Estobond P is simply applied by brush ensuring the complete surface is wetted out. Use of a “stippling” action rather than a “painting” action is recommended. The Estopatch repair mortars  or concrete should be applied immediately.



Do not over apply Estobond P as slippage of the repair mortar may occur in high build applications.

In vertical and overhead applications, whilst laboratory tests show that bond strengths are not greatly affected even after Estobond P is allowed to dry for 24 hours, practical difficulties of maintaining compaction onto the dry primer layer will reduce the build which can be achieved with Estopatch material. It is recommended therefore that should Estobond P dry longer than 8 hours at 20°C, a fresh coat be applied.

(B)   As a cement modifier

Estobond P is used as cement modifier to improve the properties of patching mortars and renders.

The recommended mix designs OPC:             50 kg

Zone 2 sand:             150 kg

Estobond P:              10 – 15 litres

Water:                         add sufficiently to give required consistency

Application instructions

(A) As a bonding agent Preparation

It is recommended that all repair areas should be defined by a 10mm saw cut to avoid “feather edging” of the repair mortars. Finally pre-soak the repair zone with copious amounts of clean water preferably for a minimum of 1 hour prior to application of the Estobond P.  Remove excess surface water with a stiff brush.



Estobond P is supplied ready for use. Do not dilute with water or solvents of any kind. Pour milky liquid into suitable container ready for application onto previously prepared substrate.

Technical Support

Estop offers a technical support package to specifiers, end-users and contractors, as well as on-site technical assistance.


Store in dry & covered condition. Estobond P has a shelf life of 12 months in an unopened container.

If stored in extreme heat condition, the shelf life may be reduced.


Estobond P is non-toxic. It is slightly alkaline; therefore, skin contact shall be avoided. Wear gloves and protective clothing.
