When installing EPDM seals for building expansion joints, avoiding common mistakes is crucial to ensure the longevity and effectiveness of the seals. Here are some key pitfalls to watch out for:

1. Inadequate Surface Preparation

• Mistake: Not cleaning the surface properly before installation.
• Solution: Ensure the surface is clean, dry, and free from debris, dust, and grease. This helps in achieving a strong bond between the EPDM seal and the substrate1.

2. Incorrect Sizing and Cutting

• Mistake: Cutting the EPDM seal inaccurately, leading to improper fit.
• Solution: Measure the expansion joint accurately and cut the EPDM seal to the exact size needed. Use sharp tools to make clean, straight cuts 2.

3. Poor Adhesive Application

• Mistake: Using the wrong type or amount of adhesive, or applying it unevenly.
• Solution: Choose a compatible adhesive and apply it evenly on both the surface and the EPDM seal. Follow the manufacturer’s instructions for the correct amount and application method1.

4. Improper Seam Preparation and Sealing

• Mistake: Not properly preparing and sealing the seams, leading to leaks and premature failure.
• Solution: Ensure seams are properly overlapped, cleaned, and primed before applying adhesive or seam tape. Press the seam tape firmly to create a watertight seal3.

5. Neglecting Regular Maintenance

• Mistake: Failing to inspect and maintain the EPDM seals regularly.
• Solution: Conduct regular inspections to check for signs of wear and tear. Clean the seals to remove any debris that could affect their performance and address any damage promptly3.

6. Incorrect Installation of Flashings and Accessories

• Mistake: Improperly installing flashings and accessories, which can compromise the seal’s integrity.
• Solution: Securely fasten and seal flashings and accessories to prevent water intrusion. Use compatible materials and techniques to ensure a proper fit1.

7. Not Allowing Adhesive to Cure

• Mistake: Not allowing sufficient time for the adhesive to cure before subjecting the seal to stress.
• Solution: Follow the manufacturer’s guidelines for curing time to ensure the adhesive sets properly and forms a strong bond2.
