Buying Guide Of Caulk For Baseboards:

We believe that you have read all the product reviews above. You have already known that either acrylic latex or siliconized baseboards are what is needed for baseboards. Still making a choice might be difficult for you. This is why we are here with the buyer’s guide which will help you in making the right decision.

Caulk type:

The most basic thing you have to consider before making a purchase is the formula of the caulk. As mentioned earlier the caulks are made of either acrylic latex or silicone or both combined together. The products are different from each other when the formulas are different. 

Generally, acrylic latex caulks are suitable for the surfaces where there is no exposure to water. They are called the painter’s caulk for their paintability and cheap pricing. 

On the other hand, the acrylic latex ones which have silicone mixed in them are the ones which can be applied on the humid areas, especially on bathroom baseboards. This type of caulk is capable of resisting mild water and does not melt away. 

Now, the silicone-based ones. They are the better ones than the acrylic ones at the point of being waterproof. If you are planning to work on the surfaces where there is a constant flow of water, then you should go for this type of caulk. The durability and water resistance feature makes them a top deal. Oh! One more thing, you can not paint over them. . 

Ultimately, you can use acrylic latex with a mixture of silicone, if you are working on baseboards. On the other hand, if you want waterproof caulking and are okay with the paintability then you must go for the siliconized ones. 

If anyone offers to sell you a paintable siliconized caulk, it is not the pure one and surely less effective.

Quality:

If a caulk does not last long, that is not a really great product. Do not compromise with caulk of good quality with anything else. 

Durability:

The acrylic latex ones offer at least 20 years of durability guaranteed and the silicon-based ones offer 35 years. If your seller does not offer you so, the suggestion would be not to purchase. You will easily find better ones in the market. 

Curing time:

By curing time it is meant the time by which the caulk settles down. This varies from product to product. It can be from one hour to 2 days. 

If you do not have much time for that then you should buy the ones which take less time to settle down. It is really hard to wait and watch caulks curing after application as you have to be careful that nobody touches it.

Resistance:

If you have faced problems previously of mold and mildew resistance, you are looking for a caulk which resists the two. 

These are a bit costly caulks but as I said earlier, make sure of a good quality over price. 

Elastomeric:

Elastomeric caulks are blessings if you are applying caulks on surfaces which can move. Elastomeric caulks can easily bend and stretch. Though you won’t be needing them if you work on baseboards, still I told it just to let you know. 

Price:

It is the most confusing part. This is where all the buyers get confused. There is only one rule to eradicate your confusion. “Look for the quality, not the price”. 

You already know the features of the silicone and acrylic latex caulks. If anyone offers you the same formula with even a single different feature and low price, that might not be the pure and effective caulk you have been looking for.

The reasonable price for the acrylic latex ones are less than one dollar per ounce and for the siliconized caulks it is under 2 dollars per ounce. Anything above is considered expensive. 

Conclusion:

We have discussed a complete guideline along with the best available product reviews. We hope you have gone through them and reached a conclusion. 

Ultimately you have to think about which caulk is the best one for baseboards of all types in any conditions. The siliconized ones are the ones which meet such purpose. We think this is why they deserve the crown. 

Still, your choice might vary according to your requirements. We tried to show you the caulks for all types of baseboards and hope that this hard work will help you realize and choose the best caulk which will work for you. Best of luck with your sealing!
