- Before use ensure that the surface or plywood and laminates is clean, dry, leveled and free of oils, excess moisture or other contaminants, such as dust, synthetic particles etc.
- The adhesive should always be stirred before use. Sufficient adhesive should be applied on either or both of the surfaces to be bonded. Don’t add water into adhesive; it makes the bonding weak.
- Once the adhesive is applied, time is crucial and it gets a bit tricky so act fast(usually requires 5-10 minutes, depending on atmospheric conditions) Ensure that the laminate is placed on the surface accurately aligned.
- Sufficient bonding procedure should be followed to ensure intimate contact which is necessary for an adequate bond to take place. It should be applied over the entire area keeping the procedure in mind without damaging the assembly. Pinch rollers(rotary press) and heavy weighted rollers are ideal. Hand rolling should be done from the center to edges to ensure the removal of all air bubbles. The edges should be rolled twice.
- For satisfactory bonding, the area in question should be kept under pressure for a period of 12-18 hours (depending on atmospheric conditions)
- In the rainy season or when humidity is too high, moisture may-condense on the surface during drying (known as “blushing”) and will prevent an acceptable bond. Hot spray or forced air drying may be used to help prevent this condition.
- It is recommended that the maximum sheet size used for vertical field application be limited to 640×2440 mm (2×8 ft.) for best outcome.
- When laminate is pasted vertically, maintain uniform pressure on all sides till adhesive is dried.
- To avoid stress cracking, avoid making cut outs having sharp corners and rough edges.
- A gap of minimum 2mm should be maintained between two laminates while pasting side by side.
