Maintenance
The M-D Building Products 91810 weather stripping requires minimal maintenance to ensure continued performance.
- Cleaning: Periodically wipe the visible surfaces of the weather stripping with a damp cloth to remove dust and debris. Avoid harsh chemicals that could degrade the vinyl coating.
- Inspection: Annually inspect the weather stripping for signs of wear, cracking, or detachment from the door frame. If significant damage is observed, replacement may be necessary to maintain optimal sealing performance.
Troubleshooting
If you encounter issues with your weather stripping, consider the following common solutions:
- Seal Not Effective: Ensure the weather stripping is fully seated in the kerf/channel. If gaps persist, verify that the correct size of weather stripping was installed for your door's gap. The product is designed for gaps up to 1/2 inch.
- Difficulty Installing: If the weather stripping is hard to push into the channel, ensure the channel is clean and free of old adhesive or debris. A small amount of silicone lubricant can sometimes aid insertion, but ensure it does not compromise the seal.
- Product Appears Creased: As noted by the manufacturer, the product may appear creased when removed from its packaging. This typically does not affect its performance once installed and allowed to settle.
- Premature Wear: Ensure the door operates smoothly and does not drag or rub excessively against the weather stripping, which can cause premature wear. Adjust door hinges or strike plates if necessary.
