Required tools & equipment:
Following tools or equipment’s shall be arranged:
- Seam sealer & Edge sealer
- Cushion back cutter or top cutter
- Notched trowel
- 50-75 lb. roller
- Mini or crab stretcher and power stretcher
- Knee kicker
- Straight edges
- Razor knives
- Hammer
- Stay nails, dry line
- Chalk line and tape measure
Procedure for the installation works:
Preparation
- Obtain necessary clearances and approvals from Engineers including MEP clearance for existing underground utilities
- Warning tape should be used around selected working area
- Ensure that area to receive the carpeting is leveled
- Ensure that the area to receive the carpeting is cleaned thoroughly from any dust, grease, and oil other contaminants. (Area should be dry)
Carpet Tile Installation
- Ensure that squareness of the room is checked
- Start point calculated by drawing using chalk line perpendicular to the room
- Ensure that the pile-lay runs in the same direction, check starting wall for squareness allowing for an off-square wall
- Align chalk line for the entire length of the area where the seam falls
- Align the seam edges with the chalk lines, ensuring that perfectly flat and tension free
- Apply adhesive and lay the carpet tiles
- Allow required time for the glue to have proper tackiness
- Using appropriate tools, set tiles properly aligned with adjacent tiles to minimize appearance of joints
Broadloom Carpet Installation
- Trowel notch size, shape and adhesive coverage rate must be maintained. Insufficient adhesive is the main cause for failure in all adhesive installation
- Proper open time must be allowed, temperature and relative humidity influence adhesive open time
- If patterned carpet is being installed, sequence must be determined based on pattern repeat size.
- If non- patterned loop pile carpet, row-cut one f the breadths to be seamed, overlap this edge over the second breadth and scribe cut to the row-cut edge. (Recommended to use hot melt seaming tape to achieve and secure pattern match on double stick installation
- Bead all edges with seam sealer on all carpets.
- Avoid air entrapment- lay carpet into adhesive working in both directions from centre.
- Roll using 75 lb. roller in both length and width directions or as directed by the cushion manufacturer in double stick application
General Pattern Procedure
- Group rolls and cuts from longest pattern to shortest
- Shift trimmed breadth to achieve a match near the mid point of the seam
- Insert hot melt tape under seam
- Melt together that portion of the seam that is visually acceptable
- Using a power stretcher or knee kicker, stretch along the short side in 3-5 feet section
- As each small section of the seam is matched, insert seaming iron and prepare the section. Leave stretcher locked in position until each section cools
- Once all seams are matched and complete, the entire installed area is stretched.
- IR to be submitted after completion of works and ensure its approval.
