Introduction

Installing rubber flooring is one of the most rewarding DIY flooring projects you can undertake. Unlike many flooring types that require specialised skills and expensive tools, rubber flooring—particularly interlocking tiles—can be installed by anyone with basic DIY competence and a few simple tools.

This comprehensive installation guide covers everything from initial planning through to finishing touches. Whether you're laying rubber flooring in a home gym, workshop, commercial facility, or any other space, the principles and techniques covered here will help you achieve a professional-quality result.

At Slip-Not, we've helped thousands of customers successfully install rubber flooring. This guide compiles the most important lessons from those projects—what works, what doesn't, and how to avoid common problems.

Before You Start

Planning Your Installation

Successful rubber flooring installation starts well before you pick up any tools. Proper planning prevents problems and waste.

1. Measure Accurately

Measure your space carefully, including all alcoves, doorways, and irregular areas. For rectangular rooms, multiply length by width. For irregular shapes, break the room into rectangles, calculate each, and add together.

Order extra material:

• Rectangular rooms: Add 5% for waste
• L-shaped or irregular rooms: Add 10% for waste
• Many obstacles or curves: Add 15% for waste

2. Choose the Right Product

Match your rubber flooring choice to your specific needs:

3. Check Your Subfloor

Before ordering materials, assess your existing subfloor:

• Concrete: Ideal substrate. Check for moisture issues and surface condition.
• Plywood/chipboard: Good if at least 18mm thick and securely fixed.
• Existing vinyl/lino: Can overlay if firmly bonded and level.
• Existing tiles: Can overlay if tiles are firmly bonded and reasonably level.
• Carpet: Must be removed—rubber should never be installed over carpet.

4. Plan Your Layout

Before installation, plan your tile or roll layout:

• Start from the most visible corner and work towards exits
• Aim for balanced cuts at edges (avoid very thin strips)
• Plan seam locations in rolls to minimise visibility
• Consider pattern direction for directional textures

Tools and Materials

Essential Tools

• Tape measure – Quality retractable tape, minimum 5m
• Chalk line – For marking straight guidelines
• Utility knife – Heavy-duty with retractable blade
• Spare blades – Essential; cutting rubber dulls blades quickly
• Straight edge – Metal ruler or purpose-made cutting guide (minimum 1m)
• Rubber mallet – For seating interlocking tiles
• Pencil or marker – For marking cut lines
• Knee pads – You'll thank yourself
• Safety glasses – Especially when cutting

Additional Tools for Roll Installation

• Notched trowel – For adhesive application (check tooth size requirements)
• Floor roller – Minimum 45kg, preferably 75-100kg
• Seam roller – For pressing down seam areas
• Adhesive spreader – For large areas

Materials

• Rubber flooring – Plus waste allowance
• Adhesive – If required (rubber-specific type)
• Primer – For porous substrates when gluing
• Edge strips – For transitions and perimeter finishing
• Levelling compound – If subfloor needs levelling
• DPM – If moisture issues present

Subfloor Preparation

This is the most important section of this guide. Poor subfloor preparation is responsible for the vast majority of rubber flooring failures. Invest time here to avoid problems later.

Concrete Subfloors

Step 1: Remove Existing Flooring (If Applicable)

If removing old flooring:

• Remove all adhesive residue (scraper, adhesive remover, or grinding)
• Remove any paint or coatings that could prevent adhesion
• Clear away all debris and dust

Step 2: Repair Damage

• Cracks: Open out slightly with a chisel, clean, fill with flexible filler
• Holes: Clean, prime, fill with rapid-set repair compound
• Flaking surface: Remove loose material, apply stabilising primer

Step 3: Check and Correct Levels

Use a 2m straight edge or spirit level to check for dips and high spots:

• Maximum acceptable variation: 3mm over 2 metres
• High spots: Grind down with concrete grinder
• Low spots: Fill with self-levelling compound
• Severely uneven: Apply full self-levelling screed

Step 4: Test Moisture Levels

Moisture is a common cause of adhesive failure and floor damage:

• Use a calibrated moisture meter
• Maximum acceptable level: 75% RH or 4% MC
• Test in multiple locations, especially near external walls
• If levels exceed limits, install surface DPM or address moisture source

According to BSRIA guidelines, new concrete requires minimum 1mm curing depth per day of drying—a 50mm slab needs at least 50 days drying before flooring installation.

Step 5: Clean Thoroughly

• Sweep or vacuum all dust and debris
• Remove any oil or grease with degreaser
• Allow to dry completely after wet cleaning
• Vacuum again immediately before installation

Wooden Subfloors

Wooden subfloors (plywood, chipboard, floorboards) require:

• Minimum 18mm thickness for rubber installation
• Secure fixing with no movement or bounce
• Re-fix any loose boards with screws (not nails)
• Fill gaps between boards with flexible filler
• Sand high spots and fill low spots
• Consider overlay with 6mm plywood for poor-condition floors

Existing Flooring Overlay

When overlaying existing hard flooring:

• Ensure existing floor is firmly bonded (tap test for hollow spots)
• Clean thoroughly with appropriate cleaner
• Lightly sand smooth surfaces to improve adhesion
• Fill any grout lines or damaged areas if they might show through

Installing Interlocking Rubber Tiles

Interlocking tiles are the easiest rubber flooring to install. Most systems require no adhesive and can be completed in hours.

Step 1: Acclimatise

Unbox tiles and spread them in the installation room 24-48 hours before fitting. Stack loosely or lean against walls—don't leave sealed in boxes.

Step 2: Plan Layout

Dry-lay a row of tiles along two perpendicular walls to check the layout:

• Measure the remaining gap at each wall
• If edge tiles would be less than half a tile width, adjust starting position
• Aim for balanced cuts at opposite edges

Step 3: Establish Starting Point

Options for starting position:

• Corner start: Begin at the most visible corner, work outward
• Centre start: For large rooms, snap chalk lines through centre, work outward in quadrants

For most home gym and workshop installations, corner start is simpler and works well.

Step 4: Install First Tile

• Position first tile with interlocking edges facing the directions you'll work towards
• Leave 5-10mm gap from walls (expansion gap)
• Ensure tile is square to the room

Step 5: Continue Installation

1. Place next tile adjacent to first, aligning interlocking edges
2. Press down firmly or tap with rubber mallet to engage the interlock
3. Continue row by row, checking alignment regularly
4. Use a straightedge to verify rows remain straight

Step 6: Cut Edge Tiles

For perimeter tiles requiring cutting:

1. Place full tile exactly on top of last full tile in row
2. Place another tile on top, pushed against wall
3. Mark cutting line using edge of top tile as guide
4. Cut along marked line using utility knife and straight edge
5. Fit cut piece with cut edge against wall

Step 7: Final Inspection

• Walk the entire floor checking for loose tiles
• Tap down any raised edges with rubber mallet
• Ensure consistent expansion gap around perimeter
• Install edge strips if required

Installing Rubber Rolls

Rubber rolls provide seamless coverage but require more skill to install. For large commercial installations, professional fitting is recommended.

Step 1: Acclimatise

Unroll rubber rolls in the installation room 24-48 hours before fitting. This is especially important for rolls that have been stored rolled—they need time to flatten.

Step 2: Plan Layout

Consider seam placement:

• Run rolls parallel to main light source to minimise seam visibility
• Avoid seams in high-traffic areas where possible
• Plan to work towards exits so you don't trap yourself

Step 3: Rough Cut to Size

1. Measure each drop length, adding 50-100mm excess each end
2. Cut rolls to length using utility knife with straight edge
3. Position cut pieces roughly in place
4. Allow to relax and flatten (may take several hours)

Step 4: Fit and Trim

For loose-lay installations:

1. Push one long edge against wall, allowing material to ride up slightly
2. Score along wall-floor junction with utility knife
3. Fold back, cut along score line, press into position
4. Repeat for opposite wall and ends
5. Butt seams tightly against adjacent pieces

For glued installations, see the adhesive installation section.

Step 5: Seaming

For basic installations, push seam edges tightly together. For watertight seams:

• Cold-weld seaming: Apply liquid seam sealer to both edges, press together
• Hot-weld seaming: Cut groove along seam, melt welding rod into groove with heat gun

Hot-weld seaming requires professional equipment and experience.

Adhesive Installation Methods

When to Use Adhesive

Adhesive installation is recommended for:

• Commercial and high-traffic areas
• Rubber rolls (almost always)
• Areas with rolling loads (trolleys, wheelchairs)
• Wet areas (prevents water ingress)
• Heavy equipment zones
• Large areas over 50m²

Choosing the Right Adhesive

Use adhesive specifically designed for rubber flooring. Types include:

• Contact adhesive: Applied to both surfaces, bonded when tacky. Good general-purpose option.
• Pressure-sensitive adhesive: Allows repositioning, suitable for tiles.
• Polyurethane adhesive: Maximum strength, recommended for heavy-duty commercial.

Always check manufacturer recommendations for your specific rubber product—incompatible adhesives can cause damage or failure.

Full Bond Installation Method

Step 1: Prime Substrate (If Required)

Porous concrete may require priming. Apply recommended primer evenly and allow to dry completely before adhesive application.

Step 2: Position Material

Position rubber flooring in final location and mark edges on the subfloor. For rolls, fold back half the length to expose subfloor.

Step 3: Apply Adhesive

1. Using notched trowel, spread adhesive on exposed subfloor
2. Maintain consistent tooth depth and angle
3. Work in sections appropriate to adhesive open time
4. Avoid applying adhesive beyond marks

Step 4: Allow Tack Time

Most adhesives require "open time" before rubber is laid:

• Check manufacturer instructions (typically 15-45 minutes)
• Adhesive should feel tacky but not transfer to finger
• In warm conditions, tack develops faster
• Don't exceed maximum open time or adhesive will skin over

Step 5: Lay Rubber

1. Carefully roll or fold rubber onto adhesive
2. Avoid trapping air—work progressively from one end
3. Press down firmly as you go
4. Do not slide rubber once contact is made

Step 6: Roll Thoroughly

Use a 75-100kg floor roller immediately after laying:

1. Roll from centre outward to expel trapped air
2. Roll in multiple directions
3. Pay special attention to edges and seams
4. Roll again after 30-60 minutes

Step 7: Repeat for Remaining Areas

Continue the process for remaining sections, butting seams tightly.

Perimeter Bond Method

For some tile installations, perimeter bonding offers a middle ground:

• Apply adhesive in 150-200mm band around room perimeter
• Apply adhesive strips at doorways and high-traffic areas
• Centre of floor remains loose-laid
• Provides stability while allowing easier future removal

Special Installation Situations

Installing Around Obstacles

For pipes, posts, and irregular obstacles:

1. Create a paper or cardboard template of the obstacle
2. Transfer template to rubber, adding 2-3mm for compression
3. Cut carefully with sharp blade
4. For circular pipes: make a straight cut from edge to pipe, cut hole, fit around pipe
5. Seal any cuts in wet areas

Doorway Transitions

Where rubber meets other flooring:

• Same height: Use flat transition strip
• Different heights: Use ramped transition or reducer strip
• Threshold: Cut rubber to fit under door with clearance

Always fit transitions securely—loose strips are trip hazards.

Stairs

Rubber flooring on stairs requires careful attention:

1. Measure each tread individually (stairs often vary)
2. Use stair nosing for safety and edge protection
3. Always glue rubber on stairs—never loose-lay
4. Apply to risers if desired for consistent appearance
5. Ensure full adhesion—bubbles or lifting on stairs are dangerous

Wet Areas

For bathrooms, changing rooms, and pool surrounds:

• Use full adhesive bond throughout
• Seal all seams with appropriate sealer
• Seal perimeter with silicone
• Choose rubber with appropriate slip resistance (R11+ recommended)
• Ensure adequate drainage falls in substrate

Underfloor Heating

Rubber is compatible with underfloor heating but requires:

• System commissioning before flooring installation
• Temperature cycling to stabilise substrate
• Maximum surface temperature of 27°C
• Heat-compatible adhesive
• Awareness of reduced heat transfer vs tiles

Finishing and Edge Treatment

Edge Finishing Options

Skirting Boards

Standard skirting neatly covers the expansion gap. Remove existing skirting before flooring installation, then refit after. Leave a small gap (2-3mm) between skirting base and rubber surface.

Metal Edge Strips

Aluminium or stainless edge strips provide durable transitions. Available in various profiles:

• Square edge (same height as rubber)
• Ramped (transition to lower surface)
• Cover strips (hide joints between materials)

Rubber Edge Pieces

Many interlocking tile systems include bevelled edge pieces that create a ramped edge where the floor meets bare substrate. Ideal for workshop and garage applications.

Silicone Sealing

For wet areas, seal the perimeter with silicone:

1. Apply masking tape above and below joint line
2. Apply silicone bead with steady pressure
3. Smooth with wet finger or tool
4. Remove tape immediately before silicone skins

Post-Installation Care

• Allow cure time: Don't rush to place heavy equipment
• Initial cleaning: Sweep and damp mop to remove any installation debris
• Protect from damage: Use furniture pads under heavy items
• Document installation: Keep product details for future reference

Common Mistakes to Avoid

Mistake 1: Skipping Subfloor Preparation

Problem: Floor bubbles, lifts, or wears unevenly.

Solution: Always clean, level, and dry the substrate properly before installation.

Mistake 2: Not Acclimatising Material

Problem: Floor expands after installation, causing buckling.

Solution: Allow 24-48 hours in installation room before fitting.

Mistake 3: No Expansion Gap

Problem: Floor buckles in warm weather.

Solution: Always leave 5-10mm gap around perimeter.

Mistake 4: Using Wrong Adhesive

Problem: Adhesive fails or damages rubber.

Solution: Use only adhesive specified for rubber flooring and your specific product.

Mistake 5: Insufficient Rolling

Problem: Air pockets and poor adhesion.

Solution: Roll thoroughly with heavy roller immediately after laying and again after 30-60 minutes.

Mistake 6: Cutting Towards Yourself

Problem: Injury from knife slipping.

Solution: Always cut away from your body, use proper straight edge, wear safety equipment.

Mistake 7: Installing Over Carpet

Problem: Unstable surface, equipment tips, floor moves.

Solution: Always remove carpet completely before rubber installation.

Mistake 8: Ignoring Moisture

Problem: Adhesive failure, mould growth, damage.

Solution: Test moisture levels, install DPM if needed.
