II. Choosing The Right
Type Of Glue

Using the appropriate type and amount of glue is crucial to ensuring lasting adhesion and a clean, professional finish. Consider the following factors when purchasing glue for your project:

A. Stone SizeGenerally, glues with higher shear strength (e.g. two-component epoxy glue) should be used for gluing smaller stones, whereas more elastic glues (e.g. modified silicones) should be used for larger sizes.

B. Carrier MaterialFind the type of component(s) you intended to glue listed above the tables below, and refer to the recommended types of glue for the specific carrier material. In general, "rapid" or "fast drying" epoxy glues are not recommended.

Carrier Material		Type Of Glue
		Two-component epoxides	Cyanoacrylate	Modified silicone	Dispersive
Hard materials	Glass
	Metal
	Ceramics
	Stone
Polymer materials (glueable)	Plastics: PPMA, PC,PS, ABS, PVC
	TPE (Thermoplastic elastomers)
	Casting resin
Porous materials	Textiles
	PU foams
	Wood
	Paper
	Cork

ApplicationWhen placing the stone onto the flat surface, press just enough so that glue spreads to the edge of the stone but does not spread out around it.

Correct Flat Surface Application

• Correct amount of glue.

Incorrect Flat Surface Application

• Too much glue.
• Too little glue.
• Uneven application of glue.

Gluing Onto a Flat Surface

• 1. Check the surface tension of the carrier material.
• 2. Clean and prepare the surface for application.
• 3. Use a syringe to fill the cavity with the appropriate amount of glue.
• 4. Use tweezers or a wax stick to apply the stone and press down gently.
• 5. Dip the cotton swab in acetone or rubbing alcohol and gently clean around the applied stone to prevent dirt settling while the glue is drying.
• 6. Allow the glue to dry for at least 12 hours or according to the producer‘s recommendation.
