Installing Tile Over Vinyl Flooring: A Comprehensive Guide
Before You Begin
Before embarking on your tile installation project, it’s crucial to assess the condition of your vinyl flooring and the underlying subfloor. Ensure that the floor is solid and exhibits minimal flexing or deflection. This will prevent the tile from cracking under the weight of foot traffic and heavy objects.
Limitations of Installing Tile Over Vinyl
There are certain limitations to consider when installing tile over vinyl flooring:
- Floor Height: Adding an additional layer of flooring will increase the overall height, which may cause issues with transitions between rooms, baseboard trim, and door frames.
- Peeling Vinyl: If the vinyl flooring is extensively peeling, it may not provide a suitable base for tile installation.
- Cushioned Vinyl: Resilient flooring with a cushioned base is not suitable for tile installation.
- Floating Vinyl: Luxury vinyl planks that are laid as a floating floor, without adhesive, are not suitable for tiling over.
Safety Considerations
Asbestos: Vinyl flooring manufactured before 1975 may contain asbestos, which poses health risks if disturbed. If you suspect asbestos, do not sand, cut, or disturb the flooring. Send a sample to a testing lab for evaluation. If asbestos is present, cover the flooring with plywood underlayment before installing tile or hire an asbestos-removal company.
Step-by-Step Instructions
1. Assess the Floor
Inspect the subfloor, joists, and vinyl flooring for any signs of damage or weakness. If necessary, install a layer of new plywood subfloor over the resilient flooring to provide additional support.
2. Spot Repair Floor
Remove any protruding nails or tacks. Cut out and remove any areas of bulging vinyl or linoleum.
3. Level Out Areas
Use floor leveling compound to fill in any slopes or dips in the floor. For large areas, use a liquid leveling compound. For smaller areas, use a thicker compound applied with a trowel or putty knife.
4. Sand Flooring
Lightly sand the vinyl flooring with an oscillating sander to create texture for the thin-set adhesive to bond to. Wear breathing and eye protection during sanding.
5. Clean Floor
Thoroughly clean the vinyl floor with TSP cleaner to remove dirt, soap, and oil residue. Rinse with plain water and let dry completely.
6. Install the Tile
Apply thinset adhesive to the vinyl flooring using a notched trowel. Install the ceramic or porcelain tile directly onto the adhesive.
When to Call a Professional
Consider calling a professional if:
- You suspect the presence of asbestos.
- The vinyl flooring is extensively peeling or damaged.
- The subfloor or joists are weak or damaged.
- You are not comfortable performing the installation yourself.
