Resilient Flooring Installation (Sheet and Tile)

Installation of Resilient Flooring (Sheet and Tile)

Chapter Introduction

This chapter covers the installation of resilient flooring, both sheet and tile, in accordance with the Red Seal requirements for the floor covering installer trade. You will learn the fundamental principles, installation procedures, quantity calculations, Canadian standards requirements, and common pitfalls to avoid on the exam.

The term resilient refers to a material that returns to its original shape after deformation. In the context of flooring, this includes vinyl (PVC), linoleum, rubber, and cork. Mastering these materials is essential to passing the interprovincial exam.

1. Types of Resilient Flooring

1.1 Sheet Flooring (Rolls)

Sheet flooring is manufactured in rolls of standard widths: 1.83 m (6 ft), 2.74 m (9 ft), 3.66 m (12 ft), and sometimes 4.57 m (15 ft). They are classified into three main categories:

Type	Typical Thickness	Application	Characteristics
Thin sheet (rotogravure)	1.5 to 2.0 mm	Light residential	Printed pattern, thin wear layer
Medium sheet (calendered)	2.0 to 3.0 mm	Medium residential, light commercial	Better durability, thicker wear layer
Thick sheet (with backing)	3.0 to 5.0 mm	Heavy commercial	Integrated backing, excellent impact resistance

Typical composition of a vinyl sheet:

Wear layer (top coat) made of polyurethane or pure PVC

Print layer (decor)

Foam or felt layer (backing)

Base layer (stabilizing)

1.2 Vinyl Composition Tile (VCT)

VCT is the most common resilient tile. Its standard dimensions are 30.48 cm × 30.48 cm (12 in × 12 in) and sometimes 25.4 cm × 25.4 cm (10 in × 10 in). Thickness ranges from 2.0 mm to 3.2 mm.

VCT composition:

Binder (vinyl resin)

Mineral fillers (limestone, clay) – approximately 80% of the weight

Plasticizers

Color pigments

Stabilizers

Important characteristics:

VCT is permeable to moisture – it must be sealed after installation

It is susceptible to indentations – heavy furniture can leave permanent marks

It requires regular maintenance with specific products (acrylic-based finishes)

1.3 Luxury Vinyl Tile (LVT)

LVT is a thicker multilayer product (3.0 to 6.5 mm) that mimics wood, stone, or concrete. It is available in tile, plank, or slab formats. Two types of installation:

Type	Installation Method	Advantages
Glue-down LVT	Adhesive applied to the substrate	Maximum stability, ideal for high-traffic areas
Floating LVT	Click-lock system	Fast installation, no glue, reversible

1.4 Linoleum

Linoleum is a natural product composed of:

Oxidized linseed oil

Wood flour

Cork powder

Natural resins

Mineral pigments

Jute backing

It is often confused with vinyl, but they are two distinct products. Linoleum is biodegradable, antistatic, and has natural antibacterial properties. It is available in sheets (2 m wide) and tiles.

2. Substrate Preparation

2.1 General Substrate Requirements

The golden rule: the substrate must be dry, clean, flat, sound, and compatible. Acceptable tolerances are:

Parameter	Maximum Tolerance	Measurement Method
Flatness	3 mm under a 3 m straightedge	3 m straightedge
Local slope	1.5 mm under a 300 mm straightedge	300 mm straightedge
Concrete moisture	≤ 4.5% (pin-type moisture meter)	Calibrated moisture meter
Concrete moisture (ASTM F2170 method)	≤ 75% RH (relative humidity)	In-situ probe
Concrete pH	7 to 10	pH paper or pH meter

2.2 Concrete Substrates

Specific requirements:

Concrete must have a minimum 28 days of curing before installation

Moisture must be tested according to ASTM F2170 (in-situ relative humidity) or ASTM F1869 (calcium chloride test)

pH must be between 7 and 10 – a pH above 10 indicates excessive alkalinity that can destroy the adhesive

Cracks must be repaired with a flexible patching compound (polymer-modified cement-based)

Moisture testing procedure (ASTM F2170):

50.Drill holes 50 mm deep into the concrete (minimum 3 holes per room)

51.Insert the relative humidity probes

52.Seal the holes with mastic

53.Wait a minimum of 72 hours for equilibration

54.Read the values – they must be ≤ 75% RH

2.3 Wood Substrates

Specific requirements:

The subfloor must be exterior-grade plywood (APA Exposure 1 or Exterior) with a minimum thickness of 15.9 mm (5/8 in)

Panel spacing must be 2 mm (to allow for expansion)

Screw or nail heads must be countersunk 1 mm below the surface

The subfloor must be dry – moisture ≤ 12% (pin-type moisture meter)

Special case of oriented strand board (OSB):

OSB is acceptable for resilient flooring, but it must be Exposure 1 grade or higher

Edges must be sanded to remove any raised areas

A felt underlayment (15 lb) or self-leveling compound is recommended to smooth the surface

2.4 Existing Substrates

Existing Substrate	Acceptable?	Conditions
Existing concrete	Yes	Must be clean, dry, free of paint or sealer
Hardwood floor	Yes	Must be sanded, free of finish, nails countersunk
Existing vinyl	Yes (with precautions)	Must be well-bonded, no multiple layers
Ceramic tile	Yes	Must be clean, free of glossy glaze (sand)
Existing linoleum	Yes	Same conditions as vinyl
Carpet	No	Must be completely removed

Important rule: Never install more than two layers of resilient flooring on top of each other. The third layer must be removed.

3. Tools and Equipment

3.1 Measuring and Marking Tools

Measuring tape (8 m minimum)

Carpenter's square (large 600 mm square)

Chalk line (blue or red chalk)

Carpenter's pencil

3 m straightedge

Tracing compass (for irregular contours)

3.2 Cutting Tools

Retractable utility knife (cutter) with hook blades for vinyl

3.4 Safety Equipment

Safety glasses

Gloves (nitrile for adhesives)

Respiratory protection (N95 mask minimum)

Knee pads

Hearing protection (if necessary)

4. Vinyl Composition Tile (VCT) Installation Procedures

4.1 Quantity Calculations

Basic formula:

Number of tiles = (Room area in m²) ÷ (Area of one tile in m²) + 5% waste

Example: Room of 4.5 m × 6 m with 30.48 cm × 30.48 cm tiles

Room area = 4.5 × 6 = 27 m²

Area of one tile = 0.3048 × 0.3048 = 0.0929 m²

Number of tiles = 27 ÷ 0.0929 = 290.6 → 291 tiles

With 5% waste: 291 × 1.05 = 306 tiles

4.2 Installation Method

Step 1: Determining the starting point

For a straight (grid) installation:

108.Find the center of the room by snapping diagonal lines

109.Snap a reference line parallel to the longest wall

110.Snap a perpendicular line to the first (use the 3-4-5 method)

3-4-5 method:

Measure 3 m on the reference line

Measure 4 m on the perpendicular line

The distance between the two points must be 5 m (3² + 4² = 5²)

Step 2: Dry lay

Lay out the tiles without adhesive to check alignment

Adjust the position of the lines so that cuts at the walls are ≥ 5 cm (avoid thin slivers)

Verify that the tiles are square to each other

Step 3: Adhesive application

Use a notched trowel suited to the adhesive (see table below)

Apply adhesive to an area of 1.5 to 2 m² at a time (limited open time)

Allow the adhesive to become translucent (open time) before laying the tiles

Adhesive Type	Recommended Trowel	Open Time
Acrylic adhesive	1.5 mm V-notches	15 to 30 minutes
Solvent-based adhesive	2 mm U-notches	10 to 20 minutes
Pressure-sensitive adhesive	1 mm V-notches	5 to 15 minutes

Step 4: Laying the tiles

Lay the tiles starting from the center toward the walls

Press firmly with the rubber mallet to ensure contact

Use 1.5 mm joint spacers between tiles if specified (some VCT is installed edge-to-edge)

Regularly check alignment with a chalk line

Step 5: Cutting and finishing

Measure each cut individually (walls are never perfectly straight)

Use the hook blade knife to cut VCT (cut from the printed side)

For pipe holes: use the hole punch or cut in two pieces

Install baseboards after installation (they must cover the 3 mm expansion joint)

Step 6: Sealing

Wait 24 hours after installation before sealing

Apply 2 to 3 coats of acrylic sealer (finish) with a foam applicator

Allow 30 to 45 minutes drying time between each coat

4.3 Diagonal Installation (at 45°)

Diagonal installation is more complex but provides an interesting visual effect. Additional steps:

140.Snap the reference line at 45° to the walls

141.Wall cuts are triangular – allow for 10 to 15% additional waste

142.Use an angle finder for irregular cuts

5. Sheet Flooring Installation Procedures

5.1 Quantity Calculations

Basic formula:

Required sheet length = Room length + 10 cm (overlap) + 5 cm (trim)

Sheet width = Room width (choose the narrowest roll that covers the width)

Example: Room of 4.2 m × 5.8 m

Available roll width: 3.66 m (12 ft) – insufficient (4.2 m > 3.66 m)

Must use a 4.57 m (15 ft) roll or create a welded seam

Required length = 5.8 + 0.10 + 0.05 = 5.95 m

Purchased area = 4.57 × 5.95 = 27.2 m²

5.2 Installation Method (Template Method)

Step 1: Preparing the template

Unroll the sheet in an adjacent room (clean and flat)

Cut the sheet to approximate size (5 cm surplus on each edge)

Roll the sheet (printed face outward) for transport

Step 2: Positioning and fitting

Unroll the sheet in the room with a 5 cm surplus against each wall

Align the pattern with the main walls (or the center of the room)

Use the tracing compass to transfer wall contours onto the sheet

Trim the excess with the hook blade knife

Step 3: Complex cuts

Situation	Technique
Straight wall	Straight cut with aluminum straightedge
Irregular wall	Tracing compass set to 5 cm
Inside corner	V-cut (relief) to allow folding
Outside corner	45° miter cut
Pipe	Hole punch or two-piece cut with overlap
Doorway	Inverted T-cut (relief)

Step 4: Adhesive application

Two main methods:

Method 1: Full spread

Apply adhesive to the entire surface with a notched trowel

Allow the appropriate open time

Unroll the sheet gradually while avoiding air bubbles

Method 2: Perimeter bonding

Apply adhesive only to the edges (15 to 20 cm) and at seams

Use a pressure-sensitive adhesive

This method is used for floating floors or when the substrate is non-absorbent

Step 5: Eliminating air bubbles

Use the heavy roller (45 kg) starting from the center toward the edges

For persistent bubbles: pierce with a fine needle and roll again

Bubbles must be eliminated before the adhesive sets

5.3 Welded Seams

When the room width exceeds the roll width, a welded seam is required:

Cold weld:

Used for short seams (less than 3 m)

Product: welding liquid (solvent) applied to the seam

Drying time: 2 to 4 hours

Hot weld:

Used for long seams (more than 3 m) or in commercial areas

Equipment: hot air gun (350 to 400 °C) and welding rod

Procedure:

189.Cut both edges with a groove cutter – 3 mm width

190.Insert the welding rod into the groove

191.Heat with the hot air gun

192.Smooth with a smoothing blade (Teflon spatula)

193.After cooling (15 minutes), trim the excess with a hook blade knife – cut in two passes (first pass at 90%, second at 100%)

6. Adhesives and Related Products

6.1 Adhesive Classification

Type	Solvent	Application	Open Time	Cleanup
Water-based acrylic	Water	VCT, LVT, sheets	15-30 min	Water

6.2 Safety Requirements for Adhesives

Consult the Safety Data Sheet (SDS) before use

Check the occupational exposure limits (OELs) – solvents have low OELs

Ensure adequate ventilation (minimum 6 air changes per hour)

Use appropriate respiratory protection (cartridge mask for solvents)

Store adhesives in a cool, dry place – temperature between 10 °C and 25 °C

6.3 Self-Leveling Underlayments

Self-leveling underlayment is used to flatten substrates:

Type	Maximum Thickness	Drying Time	Application
Cement-based (standard)	5 mm	4-6 hours	Trowel or pour
Cement-based (high performance)	20 mm	2-4 hours	Pour
Gypsum-based	10 mm	24 hours	Pour
Polymer (epoxy)	3 mm	12 hours	Trowel

Application procedure:

207.Clean the substrate (industrial vacuum)

208.Apply a primer if necessary

209.Mix the underlayment according to the manufacturer's instructions (respect the water/powder ratio)

210.Pour and spread with a notched squeegee

211.Allow to dry completely before installation (check residual moisture)

8. Professional Calculations

8.1 Area Calculation with Waste

Total area = Net area × (1 + waste rate)

Installation Type	Standard Waste Rate
Tiles, straight installation	5%
Tiles, diagonal installation	10-15%
Sheets (single piece)	3-5%
Sheets (with seams)	5-10%
LVT planks (floating)	7-10%

8.2 Adhesive Quantity Calculation

Adhesive quantity (L) = Area (m²) × Coverage rate (L/m²)

Adhesive Type	Coverage Rate (L/m²)
Acrylic (VCT)	0.25 to 0.35
Solvent-based (sheets)	0.30 to 0.40
Pressure-sensitive	0.15 to 0.20
Epoxy	0.40 to 0.50

Example: 27 m² room with VCT and acrylic adhesive

Quantity = 27 × 0.30 = 8.1 L → purchase 2 containers of 5 L (10 L)

8.3 Slope Calculation for Water Drainage

For bathrooms and laundry rooms, the minimum slope toward the drain is 1% (1 cm per meter).

Slope height = Length (m) × 0.01

10.3 Joint Problems

Symptom	Probable Cause	Solution
Joints opening up	Material shrinkage	Check temperature, use a flexible adhesive
Joints overlapping	Misaligned tiles	Reinstall the affected tiles
Weld peeling off	Incorrect gun temperature	Adjust the temperature (350-400 °C)
Dirty surface	Clean before welding

11. Environmental Considerations

11.1 Ventilation and VOCs

Volatile organic compounds (VOCs) are emitted by adhesives and flooring materials. Requirements:

Products must meet the VOC limits of the Construction Products Regulation (Canada)

Ventilation must be maintained during and after installation (minimum 72 hours)

Use low-VOC products whenever possible

11.2 Waste Management

Vinyl and VCT scraps should be recycled where possible (flooring recycling programs)

Empty adhesive containers must be emptied and dried before disposal

Used solvents are hazardous waste – never pour them down the drain

11.3 Radiant Heating and Resilient Flooring

Radiant Heating Type	Compatibility with Vinyl	Maximum Temperature
Electric (cables)	Yes (with precautions)	27 °C
Hydronic (hot water)	Yes (with precautions)	27 °C
Radiant (infrared)	Not recommended	—

Requirements for radiant heating:

The flooring must be certified for radiant heating

The surface temperature must never exceed 27 °C

The heating must be turned off 48 hours before installation

The heating can be turned back on 48 hours after installation (gradual increase of 5 °C per day)

12. Exams and Certification

12.1 Red Seal Exam Structure

The interprovincial exam for the floor covering installer trade consists of approximately 100 multiple-choice questions. Approximate distribution by domain:

Domain	Percentage of Questions
Site preparation	15%
Substrate preparation	20%
Resilient flooring installation	35%
Textile flooring (carpet) installation	20%
Finishing and inspection	10%

12.2 Exam Strategies

Read each question twice before answering

Eliminate obviously wrong answers first

Watch out for questions with "EXCEPT" – they are often tricky

Calculation questions require a calculator – check your units

Questions about standards refer to Canadian standards (CSA, ASTM, NBC)

Summary

Key points to remember:

298.Types of resilient flooring: sheets (vinyl, linoleum), tiles (VCT, LVT), each with specific characteristics and installation methods.

299.Substrate preparation: the golden rule is "dry, clean, flat, sound, and compatible." Tolerances are strict: 3 mm under a 3 m straightedge for flatness, ≤ 75% RH for concrete moisture.

300.Installation methods: VCT is installed starting from the center using the 3-4-5 method for perpendicular lines. Sheets require a template and precise cuts with the tracing compass.

301.Adhesives: choose the right type according to the flooring and substrate. Respect the open time and recommended notched trowel.

302.Standards: know the ASTM standards (F2170, F1869, F1066, F1303), the NBC (Articles 9.30.2.x), and the CE Code (Rules 8-200, 12-300, 62-118).

303.Calculations: area with waste (5% for straight installation, 10-15% for diagonal), adhesive quantity (0.25 to 0.50 L/m²), unit conversions.

304.Quality control: pre- and post-installation checks, service conditions (24 hours no traffic, 7 days no washing for VCT).

305.Safety: adequate ventilation, respiratory protection, respect OELs for solvents.

Pitfalls to Avoid

307.Confusing VCT and LVT: VCT is a thin tile (2-3 mm) that requires sealing; LVT is a thicker multilayer product that does not require sealing.

308.Forgetting acclimatization time: materials must be acclimatized in the room for 48 hours before installation – this is a frequent exam question.

309.Neglecting the moisture test: never install over a concrete substrate without performing the moisture test (ASTM F2170 or F1869). A rate > 75% RH is a cause of failure.

310.Confusing units: 1 in = 25.4 mm (not 25 mm). Conversion errors are common in calculation questions.

311.Ignoring the adhesive open time: if the adhesive has skinned over (open time exceeded), it must be removed and redone. Never install over dry adhesive.

312.Forgetting the expansion joint: allow 3 mm between the flooring and the walls. This joint is covered by the baseboards.

313.Installing more than two layers: the rule is a maximum of two layers of resilient flooring. The third must be removed.

314.Using the wrong trowel: each adhesive has a specific trowel. An unsuitable trowel gives incorrect coverage.

315.Neglecting temperature: the ambient temperature must be between 18 °C and 29 °C during installation. Temperatures that are too low affect adhesion.

316.Confusing the standards: the ASTM F2170 test measures in-situ relative humidity (≤ 75% RH), while the ASTM F1869 test measures the moisture vapor emission rate (MVER ≤ 3 lb/1000 ft²/24 h for most flooring).

317.Forgetting radiant heating protection: check compatibility and maximum temperature (27 °C) before installing.

318.Not checking the concrete pH: a pH > 10 indicates excessive alkalinity – a neutralizer or specific primer must be applied.

This chapter prepares you for Red Seal exam questions on resilient flooring. Review the tables, formulas, and standards – these are the most frequently tested elements.
