Repairing cracks in the concrete is vital in preventing further damage to the final decorative floor finish or screed. These cracks must be non-structural and the floor cracks are cleaned and opened with the saw to allow the product to penetrate and seal the joint.

Sub Floor Preparation
At Unlimited Flooring Sheffield, we pride ourselves on the quality of our floor finishes an this can only be achieved through thorough floor preparation. We have various means at our disposal which we will highlight. Once surveyed we will determine which method to employ.
- Scarifying : Effective in removing high spots in concrete and is also effective in removing paint, loose or flaky screeds/resins.
- Diamond grinding : Our Klindex and Innovotech equipment is ideal in removing uneven concrete or asphalt surfaces. Old adhesives and latex screed can be removed under this method, coupled with our high performance vacuum, the finish is environmentally friendly to staff and others on site.
Latex smoothing compound
Essential for maintaining a superior finish for decorative floor finishes. Our floorlayers will prime subfloors prior to latex screeding and we only use the highest quality smoothing underlayment.
These screeds are normally laid to a thickness of 3 mm but can be laid to a thickness of 20mm, applied with latex or water mix. Aggregates can be used to increase the thickness of the product to 30mm in some cases. Also available are superior, fast drying screeds for fast track jobs, which can accept floor finishes within 4 hours. Due to onsite demanding conditions, the screed industry have developed screeds for any situation which with our survey, we can advise which is suitable for your location.
