When the flooring at your business premises starts to show its age — whether through peeling coatings, surface cracking, or a finish that simply no longer meets the demands of your operation — it is time to consider bringing in professional help. Hiring a floor preparation company is a significant investment, and understanding the process from start to finish will help you plan effectively, minimise disruption, and ensure the best possible outcome for your new industrial floor finish.
Initial Assessment and Survey
The process begins long before any machinery arrives on site. A reputable floor preparation company will conduct a thorough initial assessment of your premises, often at no charge, to evaluate the current condition of the floor. During this visit, a trained surveyor will examine the existing coating, identify any areas of damage, contamination, or weakness, and assess the substrate beneath. This is a critical stage because the condition of the underlying concrete or screed will largely determine the scope of the work ahead.
The surveyor will test for moisture levels within the slab, as excess moisture can compromise the adhesion of any new industrial finish. They may also carry out a pull-off adhesion test to understand how well the existing coating is bonded to the substrate. In older buildings, the floor preparation company may also need to test for hazardous materials such as asbestos-containing adhesives or lead-based coatings, particularly where the floor dates back several decades. These tests are not optional niceties — they are essential safeguards that protect both the workers and your business from serious health and legal risks.
Following the survey, the floor preparation company will provide a detailed written specification outlining the work to be carried out, the machinery to be used, the timeline, and the anticipated cost. Take the time to read this document carefully and ask questions about anything that is unclear before agreeing to proceed.
Site Preparation and Planning
Once contracts are agreed, the next stage involves careful planning around your business operations. A professional floor preparation company will work with you to schedule the work in a way that causes as little disruption as possible, whether that means phasing the project across sections of the floor, working overnight, or completing the job over a weekend shutdown. Clear communication at this stage is essential, and a good contractor will be transparent about how long each phase will take and what the floor will look like during the interim.
Before work commences, the area must be cleared of all racking, equipment, machinery, and other items. The floor preparation company will advise you on exactly what needs to be moved and by whom, as liability for damage to items left in the work area can become a contentious issue if not clarified in advance. Temporary barriers, warning signage, and dust suppression measures will be put in place, particularly in premises that remain partially operational during the project.
The Removal of Old Coatings
The removal of an existing industrial coating is rarely a straightforward task, and the methods used will vary depending on the type and thickness of the coating, its current condition, and the nature of the substrate below. A skilled floor preparation company will select the most appropriate technique — or combination of techniques — to strip back the old surface efficiently without causing unnecessary damage to the concrete beneath.
Shot blasting is one of the most widely used methods in the industry. It involves propelling small steel abrasive pellets at high velocity across the floor surface, effectively stripping the coating whilst simultaneously cleaning and profiling the concrete. The machinery is largely self-contained, with built-in vacuum systems that collect the spent abrasive and debris, making it relatively clean in comparison to older methods. Grinding, using diamond-tipped discs, is another common approach used by a floor preparation company, particularly in areas where shot blasting equipment cannot easily access, such as along walls, in corners, or on uneven surfaces.
Scarifying, which uses rotating flails or cutters to mill away the surface layer, may be employed where coatings are particularly thick or where raised contaminants such as adhesive residue need to be removed more aggressively. Planing is used in more extreme cases where significant material needs to be removed across a large surface area. The floor preparation company will explain which methods are appropriate for your specific situation and why, so you can have confidence that the approach is tailored to your floor rather than simply defaulting to whatever equipment happens to be on the van.
Surface Profiling and Substrate Repair
Removing the old coating is only part of the job. Once the surface has been stripped back, the floor preparation company will assess the exposed concrete in detail. In many cases, areas of damage become apparent only after the old finish has been removed — hollows, cracks, laitance, or delamination that were previously hidden beneath the coating now need to be addressed before any new finish can be applied.
Surface profiling — achieving the correct texture and roughness on the concrete — is an equally important element of the process. Most industrial coatings require a specific surface profile to bond correctly, and this is measured using comparator standards that define the depth and texture of the prepared surface. The floor preparation company will ensure the substrate meets the profile requirements stipulated by the coating manufacturer, as failing to do so can result in premature failure of the new finish regardless of its quality.
Substrate repairs will typically involve filling cracks with appropriate repair mortars, grinding down high spots, and applying skim coats or cementitious overlays to level areas of significant unevenness. If moisture readings remain elevated, the floor preparation company may also recommend the application of a moisture suppressant primer before the main coating is laid. These remedial steps are not extras to be negotiated away — they are fundamental to the longevity of your new industrial floor.
Dust, Noise, and Environmental Considerations
One of the most common concerns amongst business owners is the level of disruption caused by floor preparation work. Dust and noise are unavoidable to some degree, but a professional floor preparation company will take all reasonable measures to contain and control both. Modern preparation equipment is fitted with industrial vacuum extraction systems designed to capture the vast majority of airborne dust at the point of generation, which is particularly important in food production, pharmaceutical, or healthcare environments where contamination is a serious concern.
Noise levels will depend on the machinery being used and the size of the area being prepared. Shot blasting and grinding equipment can be loud, and the floor preparation company should provide clear guidance on noise levels in advance so that you can inform staff, neighbours, or any other relevant parties. In sensitive environments, work may need to be restricted to specific hours in line with local environmental regulations or tenancy agreements.
Waste arising from the removal of coatings and surface debris will need to be disposed of in accordance with current waste management legislation. Where hazardous materials have been identified during the survey, the floor preparation company must hold the appropriate licences for the handling, transportation, and disposal of such waste, and you should request copies of all relevant documentation for your own records.
Final Inspection and Handover
Once the preparation work is complete, the floor preparation company should carry out a final inspection with you before handing the surface over for coating. This walkthrough is your opportunity to raise any concerns, ensure that repairs have been completed to your satisfaction, and confirm that the surface profile and cleanliness meet the specification agreed at the outset. The company should provide you with written sign-off documentation and, where applicable, records of moisture readings and pull-off test results following preparation. This paperwork is important not only for your own peace of mind but may also be required by the coating contractor or manufacturer to validate any warranty on the finished floor.
Hiring a floor preparation company is an investment in the long-term performance of your industrial floor. When the process is managed professionally and transparently, the result is a substrate that is ready to accept a new coating to the highest possible standard — giving your business premises a durable, safe, and attractive floor that will serve your operation well for many years to come.
