Can SPC flooring be installed over existing flooring?

If you’re renovating your home and wondering whether SPC flooring¹ can be installed over your existing flooring, you’re not alone. Many homeowners prefer the convenience of avoiding a full floor demolition, but is it possible and safe to install SPC over your current floor? Let’s explore this question, as well as other important considerations when laying down SPC flooring.

Yes, SPC flooring can generally be installed over existing flooring as long as the surface is clean, level, and in good condition. It’s a great way to save time and effort during your renovation project, but there are certain factors you should keep in mind to ensure a successful installation.

Let’s dive deeper into the process of installing SPC flooring over your old floors, and the pros and cons that come with it.

Is it OK to lay new flooring over old flooring?

It’s often tempting to lay new flooring over old surfaces, but it’s important to check the condition of the existing floor before doing so. If the old flooring is damaged, uneven, or not securely fastened, it may cause issues with your new SPC flooring installation.

Laying new flooring over old flooring is OK in many cases, but the surface needs to be clean, dry, and level. If your old floor is stable and flat, you can lay SPC flooring directly on top. Just ensure there are no bumps, loose tiles, or seams that could affect the new floor’s integrity.

Before laying SPC over your old floor, it’s essential to check the existing surface. Start by cleaning the old floor thoroughly to remove dirt, dust, or debris. Next, inspect for any areas that are damaged or uneven, such as cracked tiles or warped boards. If there are large gaps or high spots, you may need to use a leveling compound² to create a smooth, even surface. After ensuring the old floor is in good condition, you can proceed with the installation of SPC flooring.

What do you put under SPC flooring?

While SPC flooring is highly durable and can often be installed over existing floors, it still requires an underlayment³ in some cases. The underlayment provides a moisture barrier, soundproofing, and additional cushioning, all of which enhance the overall performance of your floor.

Underlayment is essential for most types of flooring, including SPC. The type of underlayment you need depends on the subfloor and the specific needs of your room. A foam or cork underlayment is often recommended for SPC flooring, but it’s crucial to check with the manufacturer for the most suitable option.

Different underlayment materials serve different purposes. Foam underlayment is a common choice because it provides moisture resistance, noise reduction, and comfort underfoot. However, for areas with higher moisture levels, such as basements or bathrooms, a vapor barrier⁴ underlayment may be necessary to prevent water damage. Some SPC flooring products come with an attached underlayment, which can simplify the installation process.

Is it OK to put flooring on top of flooring?

Installing new flooring over an existing floor can be a convenient solution, but it’s important to understand the potential drawbacks. For example, if the existing floor is too thick or uneven, it may interfere with the proper installation of your new SPC floor.

It’s generally okay to install flooring on top of existing flooring as long as the old floor is smooth and level. However, if the existing flooring is excessively thick, this could affect the height of the new floor, potentially causing doors to not open or close properly or creating uneven transitions between rooms.

Dive Deeper: Potential Problems with Layering Flooring

One of the risks of layering flooring is that moisture may become trapped between the old and new floors, which could lead to mold or mildew growth. This is especially true in areas with high humidity. Additionally, the increased height of the new floor can cause issues with door clearance or cause problems with transitions between different types of flooring. It’s essential to account for these potential complications when deciding whether to install SPC flooring over an existing surface.

What are the downsides of SPC flooring?

While SPC flooring is durable, water-resistant, and easy to install, it does come with some disadvantages. One of the primary downsides is its susceptibility to impact damage. Dropping heavy objects or dragging furniture can lead to scratches, dents, or cracks.

The main downsides of SPC flooring include vulnerability to scratches, impact damage, and potential cracking over time. Additionally, although SPC is water-resistant, it’s not entirely waterproof, so prolonged exposure to water could cause damage.

To mitigate these issues, consider using furniture pads to prevent scratches, avoid dropping heavy items, and clean up spills immediately. You can also use area rugs or mats in high-traffic areas to protect your SPC floor from damage. Additionally, regular maintenance, such as sweeping or vacuuming to remove debris, can help maintain the appearance of your floor.

Do you have to remove old vinyl flooring before installing new vinyl flooring?

In most cases, you do not need to remove old vinyl flooring before installing new vinyl flooring. However, you must ensure that the old vinyl is in good condition—free from tears, warping, or lifting. If the old vinyl is damaged or peeling, it’s best to remove it before proceeding with the installation.

You don’t have to remove old vinyl flooring unless it’s damaged or uneven. As long as the old vinyl is flat and intact, you can lay new vinyl flooring over it, including SPC options.

Dive Deeper: When to Remove Old Flooring

While it's not always necessary to remove old vinyl flooring, there are instances where it might be better to do so. If the old vinyl is glued down and not properly adhered, it could create bumps or uneven surfaces under the new SPC floor. If there’s significant moisture damage or mold growth, removal is necessary to ensure the integrity of the new floor.

How do you cover old flooring?

If you don’t want to remove old flooring but need to cover it, there are a few options. For example, you can use a leveling compound² to smooth out any imperfections, and then lay a fresh underlayment before installing SPC flooring. This will provide a flat surface and prevent moisture from seeping through.

To cover old flooring, you can use a leveling compound or underlayment to create a smooth surface. Once the old floor is level and clean, you can install your new SPC flooring with ease.

Dive Deeper: Best Methods for Covering Old Flooring

Using a leveling compound is one of the most effective methods for covering old flooring. However, ensure that the surface is clean and dry before applying the compound. You can also use a moisture barrier underlayment if you’re concerned about water damage or moisture buildup. Once the floor is prepped, you can install SPC flooring over the covered surface.

Can SPC flooring be installed over tile?

Yes, SPC flooring can be installed over tile. In fact, this is a common application because it’s often easier and less expensive than removing the old tile. However, before installing SPC flooring over tile, you must ensure that the tile surface is clean, level, and free from debris. Any grout lines or uneven spots may need to be filled or leveled before installation.

SPC flooring can be installed over tile, provided the surface is clean and level. It’s a great option when you don’t want to remove old tile but want the benefits of SPC flooring.

Dive Deeper: Preparing Tile for SPC Installation

If you’re installing SPC flooring over tile, be sure to check for any cracks or damage in the tile surface. You may need to fill in the grout lines or level out the floor with a compound. Ensure that the tile is firmly adhered to the subfloor to prevent any shifting after the new flooring is installed.

How do you mop SPC flooring?

Mopping SPC flooring is simple, but it’s essential to follow the right steps to ensure the floor stays in good condition. Use a microfiber mop and a damp cloth with a gentle cleaning solution to avoid damaging the surface. Avoid using excessive water, as it can seep into the seams and potentially damage the floor.

For best results, mop your SPC floors with a mild, pH-neutral cleaner. Avoid harsh chemicals that could cause discoloration or damage. Regularly sweep or vacuum to remove dust and dirt, and immediately clean up spills to avoid moisture damage.

Conclusion

SPC flooring can be installed over existing flooring, but it’s crucial to ensure that the old surface is clean, level, and in good condition.
