Silicone is a versatile, recyclable, and flexible compound that is water-resistant and heat-resistant. It is used in many arts and crafts projects and home improvement and repair plans. Because it is a durable, malleable, and non-toxic...

Using a Silicone Spray

  1. Picture 1 of How to Coat Something in Silicone
    Use a silicone spray on a variety of surfaces. A silicone spray in an aerosol container can help lubricate, protect, and waterproof a surface. It can be used on a wide variety of surfaces, including metal, glass, painted surfaces, and even fabrics.[2] In addition, it is safe to use on plastics, vinyl, and rubber.[3]
    1. Silicone sprays can be purchased at hardware stores and typically cost less than $10.[4]
    2. Consider using a silicone spray on a work surface in your home or garage to prevent objects from sticking to it.
    3. Spray the outside of a backpack to help create a water-resistant barrier.

    Allow it to dry for three days. The object will lose its stickiness in about an hour, but it will take at least 72 hours for it to dry completely.[9] Keep it in a safe place where it won't be disturbed or knocked over.
    1. If you are spraying an object with multiple sides like a tool handle or a pot handle, spray each side one at a time. Allow each side to dry for about an hour before moving on to the next.

Dipping a Light Bulb in Silicone

  1. Picture 10 of How to Coat Something in Silicone
    Select a light bulb size. Dipping a light bulb in silicone is a fun and creative project that allows you to spruce up a typical light bulb. Choose what type of light bulb you would like to use. If you would like to make a small votive light, select a 60-watt candelabra bulb. Select a 60-watt standard light bulb if you are using it in a desk lamp.
  2. Picture 11 of How to Coat Something in Silicone
    Wrap wire around the base of the bulb. Secure some craft or jewelry wire around the base of the bulb by tightly wrapping it around several times. Leave a string that is about 4 or 5 in (10 to 13 cm) long, or long enough for the bulb to be secured as it is hanging to dry.[10] Wire can be purchased online or at an arts and crafts shop and can cost between $3 to $8.[11]
    1. Use a pair of pliers to clip the wire.

    Cut the tip of the silicone caulk nozzle. Silicone caulk comes in a tube and can be purchased at a general store or a hardware store. It typically costs between $3 and $10.[12] To open, use a pair of scissors or a box cutter to carefully slice off the tip of the nozzle.[13]
    1. Be sure to use 100% silicone. You can use either white or clear silicone.
  4. Picture 13 of How to Coat Something in Silicone
    Squeeze the silicone into a plastic cup. Use a clear and disposable plastic cup to hold the silicone. Hold the nozzle above the cup and gently squeeze the contents into the container. Fill it up about half-way.[14]
    1. Add several drops of a scented oil like cinnamon or lavender into the silicone. The bulb will give off a pleasant aroma as it glows.
    2. To add some color, use a few drops of oil-based paint and mix it with the silicone.[15]
  5. Picture 14 of How to Coat Something in Silicone
    Dip the bulb into the silicone. Hold the cup securely with one hand. In the other, grip the base of the light bulb. Dip the bulb into the center of the cup into the silicone mixture.[16]
  6. Picture 15 of How to Coat Something in Silicone
    Coat the bulbs. Once you have dipped a bulb in the silicone, twirl the bulb a couple of times to evenly coat the surface. Be sure not to submerge the base of the light bulb.[17]
    1. Create an elongated, decorative tip by pulling the bulb out of the silicone quickly. You can dip the bulb into the mixture several times to achieve the look you desire.[18]
  7. Picture 16 of How to Coat Something in Silicone
    Hang the bulbs to dry. Use the metal wire to fasten the bulbs in a safe place to dry. Hang the bulbs on a coat hanger, but be sure that they do not touch. Suspend the hanger in a safe, dry, bright place to dry. Leave them to dry for several days. Silicone caulk can take 24 to 48 hours to dry completely.
  8. Picture 17 of How to Coat Something in Silicone
    Place the bulbs in a nightlight or lamp. Purchase a small nightlight or lamp at a home goods store or a general store. If the nightlight has a cover, gently slide it off to remove. Once the bulbs are dry, remove the wire. Secure the silicone-coated bulbs into the light sockets.[19] Be sure the lamps are not connected to a power source as you insert the bulbs.

    Turn on the lamps or nightlights. Plug in the lamps or nightlights to showcase your unique, quirky light-bulbs. The silicone coatings will add a warm, diffused glow to a bedroom or hallway.
    1. If you added drops of essential oil, you should be able to smell a hint of the aroma as the bulbs glow.[20]

Covering a Roof with Silicone

  1. Picture 19 of How to Coat Something in Silicone
    Purchase silicone roof coating. Visit your local hardware store and talk to an employee about adding a silicone coating to your roof. Coating your roof with silicone is an environmentally-friendly way to repair and restore your roof. The silicone coating can protect against water damage and ultraviolet light, and its reflective surface can help you cut back on energy costs.[21]
    1. A 5-gallon (19 L) bucket of silicone coating can cost between $80 and $200.[22]
    2. To cover an area of 100 sq ft (9.2 sq m), use about 1.5 gallons (5.6 L) of the silicone coating.[23]
  2. Picture 20 of How to Coat Something in Silicone
    Use this product on a flat or gently sloped roof. This product works best on flat roofs or roofs with a gentle slope. Do not coat a steep roof with an incline of 20° or greater. The coating could make the roof slippery and dangerous.[24]
  3. Picture 21 of How to Coat Something in Silicone
    Clean the roof. Before applying the product, clean the roof to remove dirt and debris. Be sure to clean the gutters and remove any plants that may be growing on the roof. Rinse the roof with water using a pressure washer or a hose. Allow it to dry completely.[25]
  4. Picture 22 of How to Coat Something in Silicone
    Repair any damage on the roof. After washing your roof, repair any cracks, splits, or blisters to make the roof water-tight before applying the silicone coating. Use a roof sealant and apply the product directly to the damaged spot with a paintbrush.[26] Cement, rubber, silicone, or fibered roof sealants can be purchased online or at hardware stores and range between $10 to $50.[27]
  5. Picture 23 of How to Coat Something in Silicone
    Seal seams on the roof. Use the sealant to secure any curbs, transition areas, or areas where different materials meet. Sealing these areas can help ensure that the roof is watertight.[28]
  6. Picture 24 of How to Coat Something in Silicone
    Mix the silicone coating thoroughly. Use a paint-mixing drill or a wooden paint stick to thoroughly mix the product.[29] This will blend the product and remove any clumps that may have formed. When you are not using the product, keep the container sealed.
  7. Picture 25 of How to Coat Something in Silicone
    Apply during a warm day. For the best results, apply the silicone coating to your roof on a warm day in the morning. The ideal temperature should be around 65° F (18° C) and no higher than 90° F (32° C).[30]
  8. Picture 26 of How to Coat Something in Silicone
    Use a paint roller to apply. Pour the product into a paint tray and use a paint roller to lift some of the product onto the roller. Opt for a 1 to 1.5 in (2.54 cm to 3.8 cm) lint-free paint roller. Try to work quickly as the product may dry or collect moisture.[31]
    1. On rubber surfaces, apply a primer coat to create a consistent thickness. [32]
  9. Picture 27 of How to Coat Something in Silicone
    Let it dry for two to six hours. If you apply multiple coats to the roof, allow it to dry for at least two to six hours between coats. The coat will fully cure in 48 hours. If you wait 48 hours to apply another coat, you may need to wash the roof again before application.[33]
