How to Effectively Protect Door Thresholds During Construction Projects

During construction or renovation projects, door thresholds are often destroyed by dirt, mud, paint splatters and sloppy spills. To avoid replacing or finishing thresholds, it is recommended that contractors use temporary threshold protection. The following is a brief description of the advantages and disadvantages of each type of threshold protection.

UV protective tape is the best adhesive threshold protection. It is 9 million thick white tape that won’t peel even when exposed to bright sunlight. UV protection tape contains chemicals in both the tape and the glue that block UV rays and make the tape resistant to both sunlight and heat. It can be used in both hot and cold climates without the worry of adhesive transfer, resulting in quick and clean removal after the project is complete. Although UV protection tape is more expensive than other tapes, it is very cost-effective when considering the cost of cleaning or repainting entrance thresholds.

Blue masking tape and blue threshold tapes are the most common tapes for protecting thresholds. These inexpensive tapes work as short-term protection only in areas with low heat or sunlight. They are known to flake and chip when exposed to sunlight and are often claimed to cause more work than the protection provided. These low-quality 2 or 3 million the tapes often leave a sticky glue residue on the thresholds, because the glue used in the tapes softens in warm temperatures.

Another option is to use a threshold guard made of molded plastic. Molded plastic threshold guards are designed to protect the most common types of thresholds in residential or commercial construction. They are the most durable threshold protection and can be used for many projects. Several threshold manufacturers offer plastic threshold protections that are specific to the threshold models they sell. Unfortunately, sturdy plastic guards are not available for every type of entrance threshold, so getting protection is not easy. There is one surface protection company on the West Coast that stocks plastic threshold protections for the two most common threshold profiles.

There are two types of threshold protection to protect sliding door rails. The first is a hinged plastic guard that flips over the sliding door tracks to keep them clear of debris. This guard attaches to the wood floor to hold it in place, so it cannot be used on sliding doors installed over cement tiles, which are commonly used on the west coast. Another option that works for protecting sliding doors installed on cement slabs is impact-resistant U-plate protection. It is a thick, heavy pressed paper protector made from recycled material and is completely reusable. The U-plate is placed over the rails when the door is open and protects the sliding door rails from dirt and grime. Like the plastic protection, Sill Pro also keeps the sliding rails clean and protects the door rails from damage that can interfere with the operation of the door.
