Features & Benefits
- Do not use Adesilex PG1 for sealing flexible joints or joints subject to movement (use products from Mapesil and Mapeflex ranges)
- Do not use Adesilex PG1 for shrinkage joints between fresh and hardened concrete (use Eporip)
- Do not use Adesilex PG1 on dirty or crumbling surfaces
- Do not use Adesilex PG1 for bonding and grouting anti-acid ceramic tiles (use Kerapoxy)
- Do not use Adesilex PG1 for levelling concrete surfaces before bonding carbon fibre fabrics (e.g. MapeWrap C UNI-AX and MapeWrap C QUADRI-AX), use MapeWrap 11 or MapeWrap 12
Technical Characteristics
Adesilex PG1 is a two-component product based on epoxy resins, selected one-grain aggregates and special additives according to a formula developed in MAPEI Research & Development laboratories.
After mixing Adesilex PG1 with hardener (part B), a thixotropic mix, easy to apply even on vertical structures in thicknesses up to 1 cm in a single layer, is obtained. Once prepared, Adesilex PG1 hardens by chemical reticulation alone in approx. 3 hours. Becomes compounds with exceptional bonding and mechanical strength.
Adesilex PG1 may also be applied on very damp surfaces as long as there is no standing water. Adesilex PG1 is especially suitable for applications in temperatures between +5°C and +23°C.
Adesilex PG1 meets the requirements designed by EN 1504-9 (“Products and systems for the protection and repair of concrete structures - Definitions, requirements, quality control and evaluation of conformity – General principles for the use of products”) and the minimum requirements claimed by EN 1504-4 (“Structural bonding”).
Application
Preparation of the substrate
To ensure good adhesion of Adesilex PG1, special care must be taken for the preparation of surfaces to be bonded.
The concrete, natural stone or brick substrate must be clean, sound and dry.
Sand-blasting is ideal to remove all loose and crumbling parts, efflorescence, cement laitance and traces of form-release oils. Then remove all dust with compressed air.
All traces of rust, paint and oil must be removed from metal surfaces, preferably by means of sand-blasting (SA 2½) down to bright metal.
With regards to fresh placed concrete, it is necessary that the concrete cures for at least 28 days before applying Adesilex PG1. This is to avoid tensions induced by hygrometric shrinkage of the concrete concentrated in the interface of the bonding.
The application temperature of Adesilex PG1 must not be below +5°C.
Preparing the mixes
The two parts of Adesilex PG1 must be mixed together. Pour part B (white) into part A (grey) and mix at a slow speed with a drill mixed with an agitator until a uniform paste is obtained (a uniform grey). The product is already pre-dosed. To avoid incomplete hardening of Adesilex PG1, do not use partial quantities. When partial quantities are necessary, use a precision electronic scale. The mixing ratio is:
- 3 parts by weight of component A
- 1 part by weight of component B
Applying the mixes
Adesilex PG1 can be applied on concrete, stone, brick or metal with a flat trowel or coat.
To obtain good bonding, it is recommended to spread the adhesive on both surfaces that need bonding and let the product penetrate well, especially on irregular surfaces.
After applying the adhesive, unite the two pieces that need bonding and keep warm until the adhesive has completely hardened. The sufficient thickness to obtain an excellent bonding strength is approximately 1-2 mm. Thanks to the excellent thixotropic property, Adesilex PG1 can also be applied vertically or on ceilings without slipping.
The surrounding temperature has an effect on the hardening time of the two products. At +23°C Adesilex PG1 remains workable for approximately 35 minutes. After this time, the products begin the hardening process.
Adesilex PG1 must be applied within the useful pot life time. It is therefore necessary to plan the work within the time limit mentioned above.
Precautions To Be Taken Before Preparation And Application
No particular precautions need to be taken with temperatures between +10°C and +30°C.
During winter, when outdoor applications at temperatures below +10°C are necessary, it is recommended to use Adesilex PG1. Heat the substrate at least 24 hours before bonding and use an appropriate insulating system to avoid freezing.
Thermal insulation must be maintained for at least the next 24 hours. Store the product in a heated environment before use.
Cleaning
Due to the high bonding strength of Adesilex PG1 even to metal, it is recommended to clean working tools with solvents (ethyl alcohol, toluol, etc.) before the product hardens.
