How Do You Stop Moisture Under Vinyl Flooring?
Despite vinyl flooring's waterproof qualities, water can still harm it.
Despite being waterproof, unforeseen water disasters like flooding,
leaks, and moisture accumulation can all cause delamination and fluid
retention. Act immediately if you notice any indications of water

damage beneath your vinyl flooring. You can avoid extra damage if you
can dry out vinyl flooring as soon as possible. Learn how to detect and
address water damage beneath vinyl floors by reading on.
What occurs if water seeps through vinyl flooring?
1. Buckled and warped planks:
Vinyl floor warping and buckling are two of the main effects of water
seepage. The flooring's core material may expand in the presence of
moisture, causing the individual planks to rise and deform. In addition
to degrading the floor's appearance, this presents a trip danger.
2. Delamination:
When water damage causes the flooring's layers to split, delamination
takes place. The layers' diminished ability to stick to one another
makes the flooring less stable and more susceptible to further
deterioration.
3. Growth of Mould and Mildew:

Mould and mildew thrive on the moisture that is trapped beneath the
floorboards. These microbes can lower indoor air quality since they
like moist conditions. Health problems can also result from the
presence of mould and mildew, particularly for those who have
respiratory disorders.
4. Stains and Discolourations:
Water seeping beneath waterproof vinyl flooring might eventually
discolour and ruin it. This might make the flooring less visually
appealing, and the stains might be difficult to get rid of in some
situations.
5. Bad Odours:
Odours in the afflicted region can result from standing water and the
formation of mould and mildew. This not only alters the atmosphere
of the room but also calls for more work to get rid of the odour.
How to Identify Water Under Vinyl Floors:

1. Deteriorating Adhesive: Do planks now move where they didn't
previously? Edges may lift and bubbles may appear as a result of
weakening adhesive bonding caused by moisture and water.
2. Deteriorating seams: Do you notice any seams opening in your vinyl
flooring when you inspect it? If so, there's probably water damage
underneath it.
3. Discolouration: Does your vinyl flooring seem to have a yellowish
tint in one or more places? Most likely, trapped moisture is to blame.
4. Bubbles or bumps: Do you notice any bumps or bubbles as you walk
across your vinyl flooring or feel it with your hands? These are
unmistakable indicators of subfloor water damage.
Pro-Tips:
-For improved moisture protection and noise reduction, always choose
high-quality underlayment.
-To reduce seepage, apply a water-resistant primer to concrete
subfloors.

-To avoid moisture buildup, keep indoor humidity levels between 30%
and 50%.
Ways to Remove Wetness from Under Vinyl Floors:
Either way, moisture beneath vinyl flooring presents issues. It might be
bonded to the subfloor or it can float on top of it. In addition to causing
the edges to lift and bubbles to form in the centre, moisture degrades
glue bonding. Additionally, it weakens and deteriorates vinyl and
encourages the formation of mould. You might be able to dry out the
floor from underneath if the subfloor is made of wood and moisture is
leaking up from the crawl area. However, you'll most likely need to
expose the concrete subfloor to let it dry out.
1. Examine the crawlspace beneath the floor for indications of
dampness on the joists. They could be darkened by mould, and you
might even notice water seeping through. Condensation is most likely
what caused the moisture.
2. For a few days, or possibly a week or two, use one or two fans to
ventilate the crawlspace in order to dry up the subfloor.

3. Deal with the moisture's obvious sources. Dig a trench outside to
redirect water that is draining through the crawlspace, for instance.
4. Examine the spaces beneath the second-story vinyl floors for any
sources of moisture. A dryer vent may be leaking humid air, or there
may be a faulty pipe that passes through the ceiling. Use fans to dry
out the ceiling after making any necessary repairs to stop the moisture.
5. Remove peeling flooring to give the subfloor's surface time to dry.
Two choices are available to you if the vinyl is glued. Either use a floor
scraper to remove it, or cover it with plastic, place 1/4-inch plywood
on top, then adhere fresh vinyl to the plywood. Scraping is challenging,
but if the flooring is spongy, you should do it. Without scraping, you
should be able to remove the vinyl from the wettest spots.
6. If moisture is causing damage to a concrete subfloor, pull or scrape
the flooring off. Uncovering the concrete is the only way to dry it out
because it has most likely not yet cured. Use a heat gun to soften the
glue if scraping vinyl is tough.

7. After removing the vinyl, dry out a concrete or wood subfloor by
running a heater and fan in the space for a day or two.
Remedial and preventative measures:
Water damage to your waterproof vinyl flooring can be avoided with
correct installation, routine maintenance, and quick response to spills
or leaks. During installation, it is essential to thoroughly seal seams
and prepare the subfloor. Using waterproof underlayment can also
add an additional degree of security.
FAQs:
1. Do all vinyl installs require a moisture barrier?
The type and position of the subfloor determine this. In order to stop
seepage and damage, moisture barriers are essential for concrete
subfloors and high-humidity locations.
2. If I find mould under my vinyl flooring, what should I do?

Before reinstalling the flooring with a moisture barrier, remove any
damaged vinyl, thoroughly clean the area with a mould remover or a
bleach-water solution, and allow it to dry fully if mould is present.
3. Can moisture issues under vinyl flooring be caused by high indoor
humidity?
Indeed, condensation and moisture retention beneath flooring can
result from high indoor humidity. To keep the humidity levels in your
home between 30% and 50%, use exhaust fans or a dehumidifier.
