1. Check the slab
Concrete must be sound, clean and dry enough for the adhesive system. Dusting concrete, dampness, oil, flaking paint, curing compounds and old adhesive can all prevent a reliable bond.
Short answer
To lay garage carpet, the installer checks the concrete, removes loose coatings or contamination, plans the roll direction and joins, applies compatible adhesive at the correct coverage, beds the carpet into the adhesive, trims edges and transitions, then confirms curing time before vehicles or heavy items return.
Concrete must be sound, clean and dry enough for the adhesive system. Dusting concrete, dampness, oil, flaking paint, curing compounds and old adhesive can all prevent a reliable bond.
Preparation may include sweeping, vacuuming, scraping, degreasing, grinding, patching or smoothing. Active water entry and persistent dampness should be fixed before carpet is installed.
Roll width, garage shape, columns, steps, doorways and shelving affect join placement. The adhesive must suit the carpet backing, concrete and expected garage use.
The carpet is laid into adhesive, seams are worked neatly, and edges and transitions are trimmed. Parking and heavy storage should wait until the handover curing guidance has passed.
Why professional installation
Most garage carpet in NZ is a low-profile polypropylene product bonded directly to concrete, not stretched over underlay. That means errors in slab preparation, adhesive spread, seam planning or moisture assessment can show up as bubbles, lifted edges, telegraphed defects or premature wear.
A professional installer can measure the garage, assess whether the slab is suitable, recommend a garage-grade product, select compatible adhesive and explain curing and maintenance. If the concrete is painted, contaminated, cracked, damp or uneven, the preparation scope should be agreed before installation starts.
Delay installation if there is active water entry, persistent dampness, loose or powdery concrete, uncured concrete, heavy oil contamination, failing paint, or cracks and high spots that need repair. Carpet is a floor finish; it does not waterproof the garage or repair the slab underneath.
Questions answered
DIY is possible for some simple garages, but FlooringPro recommends professional supply and installation because garage carpet depends on concrete assessment, preparation, adhesive compatibility, seam layout and curing. A cheap DIY install can fail if the slab is damp, dusty, painted or contaminated.
The concrete is inspected and prepared, the roll layout is planned, compatible adhesive is spread, the carpet is bedded into the adhesive, seams and edges are finished, and the floor is left to cure before vehicles or heavy items return.
Only if the coating is sound and compatible with the adhesive system. Flaking paint, weak coatings or contamination may need mechanical removal before installation.
Yes, that is usually the safest approach. One supply/install scope lets the installer match the carpet, adhesive, preparation and handover advice to the garage conditions.
