Everything you need to know when looking for underlayment for vinyl plank flooring

Choosing your underlayment carefully helps you avoid costly repairs and maintenance in the future. So, when shopping for one, these are the key insights to keep in mind:

What are the types of underlayment?

Underlayment comes in different types to suit a variety of purposes and usage. The following are the common types on the market today:

  • Rubber – This is a versatile material that provides ample moisture, mold, and mildew protection. Plus, it’s also a great insulator and sound absorber, which is beneficial if you like to maintain a quiet indoor with a comfortable temperature.
  • Cement Board – This material is well-loved for its mold-resistance and smooth texture. It’s also easy to cut.
  • Plywood – This underlayment type is known for its strength and water-resistant properties. However, it’s not so good at handling uneven weight. If you really want this material, make sure to opt for the marine-grade one, which is stronger than the normal plywood.
  • Felt – This material is a perfect fit if you’re looking for an eco-friendly option. Made from recycled fiber, felt is known for its excellent insulation and sound absorption properties.
  • Cork – Got allergies? Cork is notable for its hypoallergenic properties. It keeps mildew and mold at bay. And like felt and rubber, it’s eco-friendly.
  • Foam – This goes well with plywood flooring and is known for its affordability.
  • Particleboard – Usually ½ inch thick, particleboard has a smooth surface and attaches well to adhesives. However, it’s a brittle material, which might need to be installed alongside a strong subfloor.

What are the qualities to look for when buying a flooring underlayment?

Vinyl flooring might be durable and elegant. But it also tends to be noisy, which calls the need to find the best underlayment for vinyl plank flooring. When shopping for one, choose a type or product with these qualities:

  • Heat insulation – It can be a nightmare to walk barefoot on a cold floor during the winter. But you can actually avoid this by choosing an underlayment with good heat insulation.
  • Vapor and moisture protection – This feature comes in handy if you’re living in a flood-prone area. This also provides ample protection against water soaking into the floor during the winter.
  • Feet cushioning – Underlayment makes the floor easier to walk on, especially for the elderly with mobility challenges and toddlers.
  • Sound insulation – In a gist, underlayment is the padding between the floor and subfloor. It minimizes the sound the two structural components make as a person walks on the floor.
  • Wear resistance – Constant friction between the subfloor, floor, and feet could lead to signs of structural wear and tear. However, an underlayment serves as padding that buffers the friction.
  • Anti-microbial properties – This feature ensures you won’t have to spend too much on maintenance and repair due to the presence of mildew and mold. You can also expect less odor and stain. Plus, this helps you prevent diseases and allergies due to microbes in the flooring.
  • Clean and safe for indoor air quality – This feature helps you keep yourself, your family, and pets from the headache-inducing smell of the underlayment. Remember, check the label of the product and see if it doesn’t give off a smelly off-gas.
  • Easy to install – You can save a lot on the labor cost for the installation if the underlayment material itself is easy to set up.
  • Thickness – Choose an underlayment that’s thick enough to cover the uneven areas of the subfloor. This gives the floor a seamless and smooth finish, which significantly improves the navigability of your interior.
  • Passed compression set testing – A compression testing lets you know the weight and pressure capacity of the underlayment. And this is important to help you manage foot traffic.
  • Minimize subfloor imperfections – Most subfloors don’t have a consistent level and smooth surface. And you could compensate this with a suitable underlayment material.
  • Cost – Before you even buy an underlayment, set your budget for the material. Consult a flooring expert to help you come up with a realistic price range.
  • Sound Ratings – This comes in two types – Sound Transmission Loss (STL) and Impact Sound Transmission Test (IIC). The former refers to how well it absorbs noise from TV and people, while the latter refers to its capacity in reducing the sound of footsteps and moving furniture.

Common causes of problems with underlayment for vinyl plank flooring

Installing underlayment for vinyl plank flooring could boost your quality of life at home. But it could also cause inconveniences if you’ve chosen a sub-standard material and if it’s installed properly.

  • Poor installation – Poorly installed underlayment causes floor cupping, wherein certain portions of the flooring absorb too much moisture than the other areas. This happens if the vinyl is installed when the subfloor or underlayment is still too wet. The uneven surface that it creates may cause slip and trip injuries. Dehumidifying and removing the moisture source could solve this problem. 
  • Poor quality – By installing an underlayment, you’re expecting to enjoy a quiet indoor environment. But that’s not going to happen if you choose a sub-par material. Instead, you’ll still hear annoying noises (e.g., heavy footsteps, the thud of falling objects).

How thick should an underlayment be for vinyl flooring?

Most experts would suggest that underlayments with 2 mm to 3 mm thickness is enough. It’s also highly advisable to choose a thicker material if you’d like to have a carpeted floor. Thinner flooring materials may also do better with thinner underlayment.

It’s also practical to think about more important factors first, especially the sound and moisture absorption properties, before deciding on the thickness. Some products might not be thick, but they have the best features you need.

How to install underlayment for vinyl plank floors?

Ready for the installation? Just follow these steps to get started to avoid making the common mistakes in setting up vinyl plank and underlayment:

  1. Prepare your tools. You’ll need a tape, utility knife, hammer, vacuum (or broom and dustpan), the underlayment material, and the vinyl flooring.
  2. Inspect the subfloor. Check the subfloor for any protrusions, moisture, cracks, holes, and moisture. These are major structural concerns that need to be resolved first before setting up the underlayment. Get rid of the debris and dust.
  3. Unroll the underlayment. Roll out the strip along the wall. Then, make sure that the edges don’t overlap. For materials with adhesive strips, set up the sticky edge along the wall.
  4. Take measurements, cut the material, and adhere. Set up the roll of underlayment one at a time. And start adhering the first one next to the wall. Make sure that the rows don’t overlap.
  5. Install. Refer to the manufacturer’s manual before setting up the vinyl flooring on top of the underlayment. Some makers recommend that it’s best to install two rows of underlayment first. Then, install the vinyl on the first row. Proceed to setting up the third underlayment row, which should be followed by another vinyl set up on the second underlayment row. But for best results, always refer to the manufacturer’s installation manual or hire a professional.

Yes, you could definitely do this project yourself. But remember that poor installation could mean costly repairs and frequent maintenance. Add to that the fact that it could make the floor uneven, making your loved ones prone to slip and trip injuries.
