Description
Parex Maite G00 25kg
Parex Maite is a highly flexible multi-purpose, breathable and weatherproof mortar in powder form ready to mix with water. It can be used for a range of applications but is intended to be used in the Parextherm and Parexdirect render systems and the Parex brick slip solutions.
Suitable for:
- Adhering the insulations
- Creating a base coat with the 355 AVU mesh
- Creating decorative coloured finishes by hand or spray machine
- Using as a dash receiver with the Marbri dash aggregates
- Adhering Parex profiles
- Adhering brick slip panels and brick slips
Product intended for professional use.

Features & Benefits
Maite has the following uses:
- As an adhesive for bonding insulation, either with dabs or as a full adhesive notched layer
- Creating a reinforced base coat for the PAREXTHERM, PAREXDIRECT renders systems and PAREX brick slip systems or alternative brick slip systems when used
- For creating a decorative sprayed top coat finish, from a heavy wet cast appearance to a Tyrolean effect or as a bonding coat for the MARBRI dry or wet dash render systems
- Creating a reinforced, coloured base coat for the MARBRI dry or wet dash render systems
Suitable substrates:
- Parextherm external wall insulation systems
- Parexdirect render systems
- Parex brick slip systems
- Approved insulations of expanded polystyrene, mineral wool, phenolic, wood fibre and applications conforming to Technical Approvals
- Insulated concrete formwork systems (ICF)*
- Old EWI systems with thin coatings in need of renovation
- Siniat Weather Defence board - BBA approved systems with the PAREXTHERM render systems
- Parex approved render boards**
- Cast in-situ concrete - prepare with Micro Gobetis 3000
- Lightweight aircrete blockwork - prepare with Micro Gobetis 3000
- Concrete blockwork. n Durisol interlocking modular blocks
- Brickwork and stonework - May require the use of Micro Gobetis 3000 or 751 Lankolatex
- For bonding the Parex Profiles to masonry or render substrates
- As a base coat for the coating of phenolic, XPS and EPS foam shapes and decorative profiles
- As an adhesive and base coat for other insulations, e.g. cork, wood fibre etc.
*ICF is generally made from moulded / extruded EPS which has a shiny surface finish not suitable for receiving a render finish. Before applying the render, make sure the ICF receives a light sanding to create a roughened bonding surface.
**All Parex approved boards have an A1 fire rating. In addition, due to potential mould growth issues and possible associated health concerns Parex do not recommend for external applications the use of cement particle boards, boards that have wood particles or boards containing any form of wood fibre. These types of board are also prone to dimensional instability making them unsuitable for render applications.
Preparation
- The applications must conform with the specifications and instructions for the Parextherm and Parexdirect render systems and as detailed in the European Technical Approvals, the BBA and IAB certifications
- Equipment Required:
- Slow speed electric paddle mixer
- Stainless steel smoothing trowel and spatula
- Stainless steel notched plastering trowel (trapezoid notches of 8mm)
- Spray render machine - can also be used for applying the decorative Textured or Smooth Textured finish
- Clean tools in water after use
- Water dosage: about 4.2 litres of clean water per 25 kg bag
- Mixing: about 5 minutes to create a creamy smooth consistency
- Rest time: 5 minutes before use
- Mixture usage: 30 minutes depending on climatic conditions
Application
As an adhesive for the Parextherm Mineral, Parextherm Acrylic, Parextherm Marbri render systems and Parex brick slip systems:
- Notched - Suitable when applying to flat substrates or on render board applications - Apply a minimum 3 mm layer onto the back of the insulation board and using an 8mm notched plastering trowel create vertical strips in the adhesive. Immediately press the insulation board onto the substrate ensuring the notched effect runs vertically as this creates a natural drainage channel system. Ensure a good bond is achieved by applying a light side to side movement to the insulation
- Dabs – Apply a minimum of 5 large and even thickness dabs and a perimeter layer to the back of each insulation board to provide at least 50% coverage, then apply the board to the substrate. Ensure a good bond is achieved
Base coat with mesh - For the Parextherm Mineral, Acrylic & Marbri render systems, Parexdirect Mineral, Acrylic & Marbri render systems and Parex brick slip systems:
- Apply a minimum of 2 layers embedding the mesh near to the front face of the base coat and in compliance with the specifications, taking into account exposure to the elements
- Use the notched plastering trowel to ensure a regular thickness of 3 mm is created before the application of the mesh and that an even thickness is achieved after trowelling in the mesh to leave a smooth, regular, lined and level finish for DPR / Revlane+ finishes, 630 Cerastone, and 632 Spraystone finishes. For receiving the EHI GM / EHI GF applications leave a combed surface finish. Minimum thickness of base coat: Parextherm systems: 3 - 4mm, Parexdirect systems: 4 - 5mm.
Textured/Smooth Textured finish:
- Apply a base coat with mesh as detailed above
- Spray Maite with the help of a spray render machine
- The spraying is carried out in a ‘tyrolean’ style with a minimum of 2 coats to achieve the desired textured effect. The ‘Smooth Textured’ effect is obtained by passing a stainless steel smoothing trowel over the surface of the slightly hardened ‘Textured’ effect surface
MARBRI dash coat finishes
- Apply a base coat with mesh as detailed above
- Spray or hand apply a minimum 4 - 5 mm coat of Maite to suit the size of dash being applied. Level and line the surface
- While the Maite is still wet, apply the required dash finish, ensuring a full covering is achieved. If required, lightly press the dash finish into the Maite using a floating trowel. For a wet dash effect mix the dash into the Maite and apply as above
For use as an adhesive for the Parex Profiles:
- Mix to a heavy paste - like consistency. Apply an approximate 3 - 4mm toothed trowel layer to the back of the profile and press into place. (Maite has sufficient adhesion to hold most shapes in place. Larger shapes may require additional support)
- Allow a minimum cure period of 24 hours BEFORE performing any additional work on the adhered shape
Top coat finishes:
- All DPR / Revlane+ finishes, use with the DPR Primer or Revlane+ Regulateur
- 630 Cerastone - use with the 313 Primer
- 632 Spraystone - use with the 313 Primer
- EHI GM and EHI GF
Coverage:
These values are provided as guidance only and may vary subject to substrate conditions, thickness applied and system installed.
- As an insulation adhesive - 2.6 g/m2 (7.1- 9.6m2 per 25kg bag)
- For making the base coat with mesh - 4.5 kg/m2 (2.9 - 5.5m2 per 25kg bag)
- For making a top coat finish - 2.6 kg/m2 (7.1- 9.6m2 per 25kg bag)
Please note: on uneven substrates the consumption rate may significantly increase to gain a level and lined surface.
Limitations
- Product intended for professional use
- Do not apply to a frozen substrate or on thawing substrates. Do not use in freezing conditions. Take precautions during damp climatic conditions (Discolouration could occur)
- Do not apply on very wet substrates or where there are wet patches. (Discolouration could occur)
- Avoid applications on substrates exposed to direct sun or in hot drying winds
- Minimum application temperature: +5°C
