How to Waterproof Outdoor Lights

Step 1 – Clean

Just like the coatings and paints, caulk has a similar effect on the surface when you use it for cleaning. In fact, the effect of caulk for this particular work is greater than other materials. So, it will be better if you apply a thick coating of caulk on your outdoor lighting. For this, you have to use a damp cloth and then wipe the entire light properly. Make sure to pay proper attention to the places where you are going to apply the caulk.

Prepare Everything for Waterproof Outdoor Lights

Nothing will be as ideal as the paper towels to remove the unsightly caulk blobs. So, you can also use them for this task. In order to steer the residual caulk, you will need the utility knife, so make sure to keep that near you too.

 Step 3 – Start Caulking

The caulk is needed to be opened first. Once you have done that, follow this process carefully. You have to first identify the place where you are going to caulk. It is recommended not to hurry during this application because it can ruin all things.

Make sure to pay proper attention to the gaps where the backplate and the mounting boards usually meet. Water can go through this gap and damage your electrical connection. So, you have to pay special attention to this point.

It will be better if you can apply the chalk in a steady stream. If you have applied more than the required amount, use the utility knife to remove them. Continue the process from top to bottom and make sure to follow this technique with every lighting fixture.

 Step 4 – Smoothing Out

Once you have set the caulk perfectly, you have to now perform something interesting. Take your fingers from there and press them down inside the bowl of water that I have suggested keeping near you earlier. After that, move your finger smoothly around the area where you have applied caulk.

I know this might sound a bit crazy, but trust me, this process will help you to identify if there is any leakage along the applied area and the caulk dries in a watertight way. It will also help you to acquire a smooth look too.

 Step 5 – Clean Up

If there is any spilled caulk or any caulk residue, clean it up with the damp cloths or anything that you prefer. Do it gently so that the newly applied do not get damaged.
