Question 1

Is this really 16 mil? It feels thinner than other vapor barriers I've used.**

Accepted Answer

We understand the concern—several buyers have noted that this liner feels lighter than some other 16 mil materials. It is manufactured to a 16 mil spec, but it's a general-purpose grade rather than a heavy-duty, puncture-resistant liner. If you’re on rocky ground or expect foot traffic during installation, many DIYers on TikTok suggest stepping up to a 20 mil product for peace of mind.

Question 2

How do I handle the strong chemical smell after installation?**

Accepted Answer

A small number of users have reported a noticeable odor, especially in tight, unventilated spaces. We recommend unrolling the liner and letting it air out for 24–48 hours before final installation, or using a fan to circulate air. The smell typically dissipates within a few days. If you’re sensitive to fumes, consider wearing a mask during install and ventilating the area well.

Question 3

Will this tear easily if I drag it over gravel or sharp edges?**

Accepted Answer

Yes, this is one of the most common feedback points. The 16 mil liner can puncture or tear if pulled over rocks, staples, or other debris. Many customers recommend laying down a layer of foam board or sweeping the subfloor clean first. For heavy-duty encapsulation over rough surfaces, several Reddit users recommend going with a 20 mil or fiber-reinforced liner instead.

Question 4

I got a roll that seemed short of 100 feet. Is that common?**

Accepted Answer

While the vast majority of rolls are manufactured to length, a few buyers have reported minor shortages. If you suspect your roll is missing length, please measure it carefully and contact our customer support team. We stand behind our product and will help resolve any fulfillment issues. To be safe, we suggest ordering a bit extra if your crawl space requires a precise fit.

Question 5

Is this the right choice for a high-moisture crawl space with standing water?**

Accepted Answer

This liner is best suited for moderate moisture levels and standard crawl space encapsulation. For high water tables, sump pump areas, or constant standing water, professionals often advise a thicker, more puncture-resistant vapor barrier (20 mil or above). Many homeowners on YouTube have shown this film working well for dry-to-damp spaces, but it may not hold up long-term in extreme wet conditions.
