How to Weatherize a TV for Outdoor Use?

What steps should you take to weatherize a TV for outdoor use??

Use a Protective Outdoor TV Cover

One of the easiest and most affordable ways to protect your TV outdoors is to use a cover designed specifically for outdoor TVs. These covers completely surround the TV and secure to the unit with straps or ties. They are made of water-resistant and weatherproof materials like vinyl or polyester. When not in use, the cover shields the TV from rain, snow, dirt, and other elements.

Look for a cover that is breathable and vented to prevent moisture condensation. Make sure it is securely fitted to your specific TV model. Companies like Tiper, Peerless, and Garnetics offer excellent outdoor TV covers in a range of sizes. Using a cover when the TV is not in use adds a layer of protection from the harsh outdoor environment.

Invest in an Outdoor TV Enclosure

For the ultimate protection, consider investing in an outdoor TV enclosure or cabinet. These housings are made with weatherproof, insulated materials and designed specifically to shield TVs from outdoor conditions. They feature vents to prevent overheating, seals to block moisture, and locks to prevent theft.

Outdoor TV enclosures allow you to install a conventional TV outside. They range in price from $200 up to $1000+ depending on sizing and features. Companies like Silent Shield, SkyVue, and Storm Shell manufacture high-quality outdoor TV housing units. This solution provides 360-degree weatherproofing and secure protection.

Build a Protective Outdoor TV Cabinet

If you want a more customized solution, you can build your own protective TV cabinet for outdoor use. Use marine-grade plywood sealed with waterproof varnish or an all-weather polymer material. Design the cabinet with ventilation holes to prevent overheating and a sloped roof to drain rainwater.

Leave room at the back for cords and cables. Add a lockable door to keep the TV protected when not in use. Make sure all doors/openings have weather seals around them. Install the cabinet in an ideally covered location. This DIY option allows you to build an outdoor TV housing specific to your space.

Apply Weatherproofing Sealants

You can weatherproof your TV by applying special sealants around the edges and openings. Silicone or polyurethane caulk creates a waterproof barrier to prevent moisture ingress. Carefully apply the sealant around ventilation holes, cable inputs, control buttons, and other potential points of water entry.

Avoid getting any sealant on the screen itself. Let the sealant cure fully per the product instructions. This seals up gaps in the TV housing to protect inner electronics from rain and humidity. It provides an added layer of weatherproofing at low cost.

Use Weatherproof Cables and Connections

When setting up your outdoor TV, use cables and connections designed for outdoor use. Look for cables marketed as outdoor, weatherproof or waterproof. Tested materials like gold-plated connectors prevent corrosion. Use conduit or cable coating for extra protection.

For power, install an outdoor outlet with a weatherproof cover to plug in the TV. You can also use a weatherproof extension cord to the nearest indoor outlet. Having outdoor-rated cables and connections prevents moisture from entering through the wires and damaging your TV.

Ideal Placement for an Outdoor TV

Where you mount or position your outdoor TV impacts its weatherization. Look for placement under an eave, patio cover, pergola or other covered spot. This shields the TV from direct sun and rainfall. If no cover exists, build a canopy or overhang to protect it.

Angle the TV to prevent sun glare. Keep it out of low areas that can collect rain or irrigation water. Face the back of the TV away from prevailing winds and storms. Proper placement minimizes exposure to wet weather and sunlight, the two biggest threats to TVs outdoors.

Keep the Outdoor TV Screen Clean

Dirt, dust, pollen and other debris can accumulate quickly on an outdoor TV’s screen. Clean the screen regularly using a microfiber cloth and water or electronic-safe cleaner. Avoid harsh chemicals. Wipe dirt and water spots away to maintain optimal viewing quality.

You can also apply a water-repellant screen protector made for outdoor displays. This creates a hydrophobic barrier that prevents water spots on the screen. Keeping the outdoor TV screen free of grime enhances visibility and prevents particle damage to the display.

Monitor for Any Signs of Damage

When using a TV outdoors, be sure to periodically inspect it for any wear or damage issues. Look for cracks in the casing that need to be resealed. Check that cable connections are clean and dry. Note any pixels or screen anomalies indicating internal moisture damage.

Catching problems early allows you to address them before they worsen. It also alerts you if your weatherproofing methods need improvement. Monitoring your outdoor TV and making adjustments ensures maximum longevity.

What type of outdoor TV cover is best for protection?

Outdoor TV covers come in a few different materials, so consider which would work best for your climate:

  • Screen protector – Some enclosures have built-in acrylic shields to protect the TV screen itself from damage. These provide an extra layer of defense.
  • Dimensions – Check that the enclosure is appropriately sized for your TV model with sufficient ventilation space. Measure carefully for accuracy.
  • Outdoor rating – Verify the enclosure has a NEMA 3R or IP55 outdoor rating to withstand weather extremes. This ensures true all-season performance.

What precautions should be taken when building a DIY outdoor TV cabinet?

Building your own outdoor TV cabinet has lots of advantages, but requires some cautions as well:

  • Use marine-grade plywood or composite wood that can resist moisture, rot, and wood-boring insects. Regular plywood will quickly deteriorate outside.
  • Be sure to treat the wood with a water-sealer designed for outdoor use. Apply multiple coats for best protection. Reapply annually.
  • Design the cabinet with adequate ventilation, either through vents across the top/bottom or louvered sides. This prevents hot air and moisture build-up inside.
  • Sloping the cabinet roof allows rainfall to drain off and prevents water pooling. Overhangs also help keep rain off the enclosure.
  • Caulk around all joints and seams with a flexible waterproof sealant. This prevents water entry through any cracks or openings.
  • Only install a glass TV screen protector if needed for strength. Avoid solid glass doors to prevent heat buildup inside the cabinet.
  • Situation the cabinet in an ideally covered location, avoiding direct sun and rain exposure as much as possible.
  • Check your DIY cabinet frequently for any signs of weathering damage, cracks, or leaks. Make repairs immediately as needed.

What is the best way to apply sealant when weatherproofing a TV??

When applying weatherproofing sealant to a TV, follow these tips for best results:

  • Clean the surfaces thoroughly before applying any sealant. Remove any dirt, dust, oil, or debris that could impede adhesion.
  • Choose 100% silicone, polyurethane, or marine-grade polymer sealant designed for outdoor use. Avoid cheap,general-purpose caulk.
  • Lay the TV down flat to avoid excess sealant dripping. Seal all sides and back facing up. Let dry completely before rotating.
  • Apply using a caulk gun, filling any cracks and crevices around vents, buttons, etc. Smooth with a plastic spreader for a tidy finish.
  • Goop around cables and connections, but leave a bit of space for expansion and contraction to avoid cracking. Don’t seal cables tightly.
  • Put extra sealant near the base, as moisture entry is most likely here. Build up thicker application in vulnerable spots.
  • Cure the sealant fully before mounting the TV outside. This prevents drips or runs down the screen. Follow manufacturer curing times.
  • Take care to keep sealant off the screen itself during application. Use painter’s tape on the screen edges if needed.
