Things to Consider When Buying Basement Waterproofing Paints

Before you decide to spend your precious money on one of these options, you need to consider a couple of important things. And they are:

Formula

There are basically two types of formula. One is water-based, and the other is solvent-based. Our recommendation would be to pick the water-based ones because they are usually environment-friendly. Additionally, they are easier to work with.

Curing Time

Not all of the formulas dry to the touch instantly. Some even require days. And the ones that do require days to cure will be hard to work with because you will need to wait for a reasonable amount of time before applying a second or third coat.

Water Pressure Resistance

It is pretty important to factor in the water pressure resistance rating. The higher the rating, the better. If you end up purchasing something that has a comparatively low water pressure rating, you might find the basement wall soaking up leaking water in about a couple of months.

Spread Rating

Another rating that is pretty important for these is the spread rating. You will need to use a couple of tubs for covering the entire basement if you get something that has a relatively low spread rate.

Lifespan

You should also prioritize the lifespan of the paints. It would not be a good decision to opt for something that has a relatively low lifespan. With those, you will find yourself repainting the entire basement quite often.

Odor

You do not want the basement to smell like a chemical mess, would you? For that reason, we recommend opting for something that has a low level of odor. Also, the ones that have low odor tend to have no harmful elements as well.

Application Process

Finally, consider the application process. The easier the application process, the less the number of hassles you would have to go through. Also, usually, the ones that are easier to apply will not require any mixing either.

Frequently Asked Question

How much waterproof seal do I need for my basement?

That will depend on the size of the basement and the spread rating of the formula. The smaller the size and higher the spread rating, the less amount of sealer you will need.

Are all waterproof sealers odor-free?

Not really. Even the ones that are environment-friendly will have a small amount of odor.

Do water-based sealers have VOC?

Usually, the water-based sealers will not contain VOC. Some will not even have any harmful elements.

How much time does waterproofing paint take to cure?

It will depend on the formula. Some will dry up within four hours, while some will take up to four to five days to properly cure.

Can I re-coat the waterproofing paint before it cures?

No! You should not apply a second coating before the previous coating cures or dries up completely. For best results, wait a little longer than the recommended time and apply the second coat.

Final Words

Getting one of the top-rated basement waterproofing paint options is not that easy, considering that there are way too many offerings out there. But we do hope that we were capable of making the choosing process a bit easier for you.
