Fiberglass Doors: Maintenance Tips

Fiberglass doors offer widespread appeal due to their beauty, strength and customization with paint and hardware. Like any door, fiberglass doors need to be maintained. The elements can wear down the fiberglass, paint or fixtures. You need to be proactive with the maintenance of fiberglass doors. The article that follows will give you some tips to help you stay on top of maintaining fiberglass doors.

Staining and Finishing Fiberglass Doors

One of the simplest maintenance tasks you can take to make fiberglass doors not only look great but last longer is to refinish it. You can stain fiberglass doors just like you would stain a wooden door. When you purchase fiberglass doors you will usually get a warranty of up to five years with it. Check the warranty and, if the fiberglass door is still under it, you may not have to pay to have it refinished. If you happened to paint the door and you want to now stain it you will have to strip the paint off the fiberglass door.

Clean Fiberglass Doors Regularly

Since fiberglass doors are used as entry doors they will come in contact with many harsh elements from rain and snow to high winds and debris. Certain elements can cause the fiberglass to erode and the finish to wear off the fiberglass doors. Regularly cleaning of fiberglass doors, both of the front facade and the inside, will help keep the door in pristine condition throughout its life. You can use mild soap mixed in water to clean the door unless you are planning on refinishing it within a couple days of cleaning it. The oily residue that some soaps leave behind can hinder the staining process.

Fixture Updating and Maintaining

Front entry doors get a lot of action over the course of a year. Hinges, door knobs and other pieces of hardware and fixtures will wear out over time. Replacing these items is simple to do and is also fairly inexpensive as well. Changing out the hinges for new ones will not only keep the door swinging freely but can add more appeal to the door. If the hinges or door knob are sticking or give resistance but are still in good shape you can oil them instead of replacing them. A few squirts of oil in the hinge pins and inside the door knob will add longevity to fiberglass doors.

Door Guards

For very little money you can install metal or rubber door guards to the top, bottom and door knob side of fiberglass doors. They are easily installed with a few screws but protect the door against dings, scratches, scuffs and general wear from daily use. An added bonus to using door guards on fiberglass doors is that you can be adding insulation to your home so you can save some money on your utility bills.

Caring for an Exterior Fiberglass Door

An exterior fiberglass door combines the appealing qualities of a wood door with none of the warping problems that can result from water seeping into the wood. Fiberglass exterior doors do need periodic maintenance to keep up their protective finishes. Following some basic cleaning tips will go a long way towards preserving the life of your door.

Door Stain and Clear Coats

Fiberglass doors are initially stained with oil based colored pigments that can range from light blonde to deep mahogany and are meant to give them the appearance of genuine wood. They are then sealed with a clear coat that is similar to the protective urethane coats used on wood. Once the gloss on the fiberglass has started to become dull, this is a good indication it is time for a new coat.

While the difference from wood is that fiberglass will not lose its shape from wear and tear, its clear protective finish can eventually be worn away by direct sunlight, rain, wind, and other elements of nature. Some fiberglass door manufacturers offer a warranty on their door's clear coats for a certain amount of time, so it is advised to check if this is an option when purchasing.

Correct Fiberglass Cleaning

When the time comes to reapply a new coat of stain and clear finish to your fiberglass door, the first step is to make sure you are working with a clean surface. It is recommended to use a fiberglass staining and finishing kit, available at major hardware retailers. These kits should include a fiberglass safe cleaner; if not, check the manufacturer's specifications for an approved cleaning compound. Do not clean fiberglass with soap or any other type of household cleanser; doing so can leave film and residue behind that will not allow the stain and clear coating to work correctly.

Some fiberglass staining and refinishing kits come with a small sample piece of unsealed fiberglass; this is meant to give you a guideline to help determine how much the clear coating on your fiberglass door has worn down. Apply a clear coating to the piece of fiberglass according to instructions and keep it indoors in a cool, dry place. Each year, compare the finish of this piece with that of your exterior door; this will give you an idea of whether the door itself needs a new coating.

Optimal Temperature

How hot or cold the surrounding air is can have an impact on fiberglass doors when reapplying stain and finish. Most door manufacturers recommend working out of direct sunlight and only in temperatures between 50 and 90 degrees. One option is to refinish your door inside your garage; just make sure to leave the garage door up for ventilation. Also try to avoid doing this project on windy days to prevent the new coats of stain from drying too quickly.

Light Vs. Dark Stains

Some fiberglass staining and refinishing kits specify different drying times between coats for light and dark colored stains. Follow these instructions carefully, since waiting too long or too short a time can result in a blotchy appearance on your door. Most fiberglass door stains have a minimum drying time of several days once you apply all coats of stain. After this, apply your final thin coats of clear finish.
