Frequently Asked Questions

What installation materials do I need for a flooring project?
The materials required depend on the flooring type and installation method. Most floating floor installations require underlayment, spacers, and transition strips. Glue-down installations require the appropriate adhesive and a correctly notched trowel. Tile installations require thinset mortar, tile spacers, grout, and grout sealer. Hardwood nail-down installations require flooring cleats or staples. Regardless of format, most projects also need floor moldings to cover expansion gaps at walls and transitions between different flooring surfaces. Buying the right installation materials upfront prevents delays mid-project.
What is the difference between thinset and mastic adhesive for tile?
Thinset is a cement-based mortar mixed with water or a latex additive. It is suitable for most tile installations including floors, showers, and exterior applications, and is the correct choice for large-format tile, natural stone, and any wet area. Mastic is a premixed organic adhesive that is easier to work with but is not waterproof and is not suitable for wet areas, large tiles, or floors. For most floor tile installations, thinset is the correct product. Using mastic on a floor or in a wet area is a common mistake that leads to tile failure over time.
Do I always need underlayment?
Not always, but in most cases yes. Underlayment cushions the floor, reduces sound, provides a moisture barrier over concrete, and helps the floor feel more comfortable underfoot. Many LVP and laminate products come with underlayment pre-attached to the plank -- if yours does not, adding a compatible underlayment is strongly recommended. For tile installations, an uncoupling membrane or backer board is used instead of foam underlayment. Always check the product manufacturer requirements before purchasing underlayment, as using the wrong type or thickness can void the warranty.
How do I choose the right transition strip?
The right transition strip depends on the height difference and relationship between the two surfaces it connects. A T-molding connects two floors of equal height in a doorway. A reducer transitions from a higher floor down to a lower one. An end cap finishes a floor edge where it meets a vertical surface or stops at a threshold. A stair nosing finishes the exposed edge of a step. Matching the transition to the specific situation keeps the installation looking clean and protects exposed floor edges from damage and moisture.
How much adhesive do I need for my project?
Adhesive coverage rates are listed on the product label in square feet per gallon. Calculate your total square footage and divide by the coverage rate to determine the quantity needed. Always purchase slightly more than your calculation -- coverage rates assume ideal conditions and a consistent application technique. Factors like subfloor porosity, trowel wear, and application consistency can reduce real-world coverage. Running out of adhesive mid-project and needing to continue with a different lot can affect bond consistency across the floor.
What is an uncoupling membrane and when do I need it?
An uncoupling membrane is a thin, structured polyethylene mat installed between the subfloor and tile. It decouples the tile from the subfloor, meaning the two layers can move independently and stress from subfloor movement is not transferred up into the tile and grout. This prevents cracking in the tile and grout joints over time, particularly over wood subfloors that flex and expand. Uncoupling membranes also provide a moisture management layer over concrete. They are strongly recommended for tile installations over plywood subfloors and in any situation where subfloor movement is a concern.
