Surface Preparation

Resin and hardener must be kept in 77°F (25°C) for 24 hours before application. All surfaces must be clear of any grease, dust, hardeners, and other contaminants and should also be clean and dry before applying epoxy adhesives. The surface of any product to be adhered must be prepared to access the pure hard surface underneath which is to be covered with the adhesive completely. The surface must first be sanded with an abrasive roller with a diamond blade, the resulting dust should be removed with a fiber brush. After that, the remaining dust can be removed from the surface with a damp sponge to ensure complete contact. Finally, dry the surface completely with a piece of cloth, then start using the adhesive.

Mixing Megatite S Epoxy Adhesive

Use the spatula to mix thoroughly by 1:1 ratio (1 parts resin, 1 part hardener). Mix for minimum 2 minutes until a homogeneous mix is obtained.

Processing

The strength and durability of a bonded joint are dependent on proper treatment of the surfaces to be bonded. At the very least, joint surfaces should be cleaned with a good degreasing agent such as acetone, to remove all traces of oil, grease and dirt.

In concrete surfaces must be completely solid with no loose pieces. Iron surfaces must be cleaned of rust.

Tile size Adhesive spot diameter
300*300 mm
50 mm
600*600 mm 100 mm
900*900 mm 150 mm

 

In addition, the amount of Megatite S adhesive used depends on the weight of the stone or tile to be attached to the wall. The following table is set to cover 10% of the surface of each tile with adhesive:

The amount of inclination of the wall Thickness of adhesive layer Coverage with 10kg of adhesive
Completely vertical wall 3mm thickness 16-17 m2
6mm inclined wall 6mm thickness 8-9 m2
12mm inclined wall 12mm thickness 4-4.4 m2

After the tile was set in place, necessary settings for regulation and leveling of the adhesive can be performed.
For larger stones and tiles, place spots with approximately 60g in 30cm distances from one another (horizontally and vertically) as shown in the following pattern.

Equipment Maintenance

After applying adhesive, tools and surfaces can be cleaned with warm water. Adding soap would easy the process. Megatite S can be cleaned with thinners before it is fully cured.

Packaging

Each product comes with two parts (resin and hardener), two spatulas and elastic gloves in the following packages:

2 Kilograms
10 Kilograms
20 Kilograms

Storage and Shelf Life

Maximum storage life for sealed products is 24 months if stored at 32-95 °F (0-35°C) with no change in adhesion nor appearance

Precautionary Information

  • Keep out of reach of children
  • Megatite adhesives are non-toxic and have low odor
  • In cold temperatures, avoid crossing over the work site until the adhesive is completely hardened
  • Resin is harmful to eyes and skin. Prolonged contact with it must be avoided. In case of contact, rinse immediately with plenty of water. Use suitable gloves when applying.
