Caulk is a rubbery filling compound used to seal joints and seams against water and air leakages in various fixtures and structures. Caulk usually is waterproof, and its seal protects against moisture, insect, air, or dust intrusion. Caulking is a common top-priority home improvement task that should not be ignored.
Although many DIYers are unsure of themselves when it comes to caulking, applying caulk to a tub, toilet, or counter is easy and all about confidence. Below we will take you through a simple step-by-step process to make sure you can apply your caulk evenly.
Preparations Before You Begin Caulking
To successfully apply caulk right, you must first consider preparing everything needed for the caulking activity. If you need to remove caulk before applying new caulk, the easiest way is with a utility or putty knife.
When applying caulk, avoid caulking the entire base at once. It does not matter if you are applying caulk around the toilet, tub, or bathroom counter.
Most caulk takes 1-2 days to fully dry, but it will begin solidifying within 30 seconds. Instead, break the work up into small sections, so you make sure the caulk is smooth and does not have wrinkles.
Understand that caulk may not come out of the tube evenly, but you can even it out by smoothing or sanding it after it is applied.
Use Your Finger to Smooth Out Caulk Initially
If you are a DIYer and just starting out, you do not need to use tools to smooth caulk. You can use your finger. If you want, you can use disposable gloves to keep the caulk from getting under your nails.
Spray the area with a soapy water mix to help the caulk apply smooth and not stick to your fingers as much. Smoothing with your finger should be a firm quick motion; do not stop in the middle of smoothing. If you also press down too hard, you will break the line of caulk.
Do not smooth caulk in multiple directions. The direction you apply it should be the direction you smooth it. Otherwise, you risk tearing or creating bubbles in the caulk.

Professional Smoothing Tools
A thin Jointing spatula can be used to smooth out caulk; it is a professional caulking tool for removing dried sealant and smoothing caulk. A good jointing spatula should cost around $10.
If you are not satisfied with your finger but do not have access to a jointing spatula, you can use a butter knife, damp rag, or popsicle stick to smooth the caulk.
No matter what you use, make sure to wet it first. This will reduce the chances of ripping or tearing the caulk.
Use Masking Tape to Caulk
Using masking tape is a proactive measure and won’t achieve perfect results by itself. However, this does ensure your caulk will not smear into multiple areas. Use a ruler to make sure the tape is lined up straight; otherwise, the caulk line will look uneven.

Finishing Caulk
Your caulking job does not have to be perfect when you smooth it with your finger or another object. You need to make sure the line is straight and there are no bubbles. You can now sand your caulk down after applying it and letting it dry for a day or two.
Sanding caulk involves taking sandpaper or a sanding sponge and scrubbing the caulk with the grain. Rubbing sandpaper against the grain gives caulk a smooth appearance and feel you would similarly see in a professionally caulked bathroom.
