The Top 8 Best Caulk For Exterior Windows And Doors in 2018

Caulks are materials that are used to fill in holes, gaps or cracks that develop on a surface probably due to age, weather or consistent use. The whole point of caulks or caulking is to achieve a smooth, uniform, level and consistent look and value. Your building or apartment may have developed some cracks over the years, or maybe you got those cracks when the building was under construction. You need to seriously caulk it up.

Exterior caulks are used to seal up holes and gaps on the exterior of your building. And this is a little more serious than it sounds because a little more attention needs to be paid to exterior caulking than interior caulking. This is because exterior caulks need to be strong enough to withstand and weather all the opposite extremities of nature (both hot and cold). Outdoor caulks should never fail because when they do, other stuff that should not are able to get in. This review will give you the best exterior caulks that are available for your use and for the integrity of your building.

Exterior Caulks Buying Guide

As discussed in the first lines of this article, it is very important that you buy the best caulks for both your interior and exterior works. Exterior caulks are used in all things caulking like filling gaps in your roofline, frames of your door, cracks in your window and window sills, and others. Quality and durable exterior caulk are necessary to fill up all the gaps and holes properly and permanently. Caulks are materials that you should never cut corners on or you may find yourself becoming homeless faster than you can imagine. Exterior caulks keep water and other elements outside where they belong so you need to get the best exterior caulks possible. The following is a list of things that you should consider when buying exterior caulks:

Caulk Material: Different caulks are made from different materials. Some caulks are made from acrylic, some are made of silicone, some are made of latex, some are made of polyurethane and some are made of a combination of some or all of these materials. The material considered best for exterior caulks is silicone. Silicone is highly resilient, elastic and can withstand and extreme weather conditions. However, a caulk that contains a combination of all the above materials in the correct proportion is always better than a caulk containing only silicone. The best caulk material is elastic. This means that when temperatures are high, it will stretch to accommodate the increase in temperature; and when temperatures are low, it will shrink down to its original dimensions to offset the decrease in temperature. A caulking material that is not elastic will not be able to expand to accommodate changes in temperature and it will crack or break. When it cracks, it allows an influx of water, and this is generally considered to be bad. The best caulk material is also water-resistant. Meaning that it does not let in so much as the least amount of water. A caulking material that lets in water is no caulk material at all.

Adhesion to Surface: Caulk should, as a rule of thumb, be able to stick to any surfaces, even the toughest ones. Caulk that does not stick to almost every surface or is selective in adhering to surfaces may not be of much use to you. You would need to buy a different exterior caulk for a different exterior surface. Not only does that waste a lot of resources, it completely makes no sense. So consider buying a caulk that will stick to every surface be it your walkway, driveway, vent, glass panes, window sill, door frames, eaves, wires, pipes, and pretty much every surface in your house. If it is an exterior surface, your caulk must adhere to it. Also, buy caulks that are insoluble in water. If a caulk is water-soluble, it will come off your wall in a heartbeat when rain or snow comes in contact with it.

Drying and Curing Time: Different caulks take a different amount of time to dry and cure. A caulk is dry when it is no longer wet to touch. But the fact that it is dry does not mean that it is raring to go or that it is cured. The caulk is cured when it is completely dry to touch and dry in all its components so that water and other elements do not affect it any longer. Try to buy caulks that dry and cure in as short a period of time as possible, especially during the rains or you may need several applications and re-applications of caulk before your exterior is completely protected.

Conclusion

exterior caulks are meant to protect your exteriors from recurrent repair work. So a caulk defeats its purpose if you need to reapply it over and over again. Buy caulks that are durable. Some are guaranteed to last for over thirty years. Caulks like that are good for you. Buy caulks that can be repainted to match the color of the exteriors you are caulking. And as always, we encourage you to please stay within your budget. Thank you for reading our review.
