Here we’ll discuss everything you need to know about the best exterior caulk – what they are, how they are used, what are the best exterior caulks you can get at a reasonable price, as well as what you should remember when buying exterior caulk.

What to Consider When Purchasing a Caulk

To invest the best caulk for trim, baseboards, and others, it would be best to consider the following factors:

  • Materials: A couple of caulks provide better adhesion to certain surfaces, so you need to consider carefully the surface applied before deciding.
  • Moisture: Is the caulked surface drier or wetter? In the wet conditions, you will need a caulk with the waterproof and mildew-resistant capacity.
  • Location: The exterior caulks are a prioritized option if you need to caulk outdoors.
  • Paintable: Not all caulks are paintable. If your demand is the best paintable caulk, the best plan would be to check the time before buying. Hitch Property Constructions has a wide range of caulking services
  • Application: Instead of choosing to purchase a caulk that requires you to use chemicals to clean, you can prioritize to select the caulks cleaned up with water. It is important that these caulks are non-odour and safe.

How to Apply Caulk Properly

  • When applying caulk for cracks and joints, remember to keep it up to ½ inch wide.
  • You should apply caulk on a painted surface without dust. It’s better to paint a primer coat before caulking.
  • You always need to paint the wood surface before caulking it.
  • Cutting the tip of the caulk tube decreases the amount of caulk flowing out of the tube in place of creating a big hole. Never do that.
  • You had better use a putty knife to widen the under ¼ inch joints and cracks before caulking.
  • Move the gun slowly while applying caulk.
  • To avoid causing a mess, you should use a damp cloth to clean the spout and your hands as well. After applying within 2-5 minutes, you are allowed to use a wet caulk-smoothing tool.
  • If you caulk around mouldings, make sure to fill the crack enough only. Moreover, you have to put enough pressure with the tip of your fingers as long as it is shaped into a clean corner joint. Pay attention that it’s hard to paint around joints.
  • Before caulking, you must also clean shower, bidets, sinks, lavatories, and tubs because applying it over mould, mildew, and the wet surface may not adhere properly.
  • Get rid of body oils, soap scum and other residues by swabbing the joint with rubbing alcohol.
  • It’s good to caulk your bathtub after you fill it with water because the weight of the water can produce strains which create the biggest possible joints between your bathtub and the wall.
  • Use low-tack tape for a sensitive and finished surface after each near finish. This makes the caulk dry faster.
  • Sometimes, caulk may shrink after drying. In this case, you need to caulk another layer to produce a neater surface in place of overfilling your crack.
  • Removing old caulk carefully before applying over previous and existing sealed joints. When it comes to masonry and concrete surfaces, it’s better to use a wire brush to remove the caulk.
  • Silicone caulk requires mineral spirits to clean the areas around the caulk. Meanwhile, you can use the combination of soap and water for others.
