When the flooring at your business premises begins to exhibit signs of ageing, such as peeling coatings, surface flaking, or a finish that is no longer suitable for your operation, it is time to consider enlisting the assistance of a professional. The hiring of a floor preparation company is a substantial investment, and it is crucial to comprehend the entire process from beginning to end in order to effectively plan, minimise disruption, and guarantee the best possible outcome for your new industrial floor finish.
Survey and Initial Assessment
The procedure commences prior to the arrival of any apparatus on the premises. A comprehensive initial assessment of your premises, frequently at no cost, will be conducted by a reputable floor preparation company to evaluate the current condition of the floor. A trained surveyor will evaluate the substrate beneath, identify any areas of damage, contamination, or weakness, and investigate the existing coating during this visit. This is a critical phase, as the extent of the forthcoming work from a floor preparation company will be significantly influenced by the condition of the underlying concrete or screed.
The adhesion of any new industrial finish can be compromised by excess moisture, which is why the surveyor will assess the moisture levels within the slab. Additionally, they may implement a pull-off adhesion test to evaluate the degree of adhesion between the substrate and the existing coating. In older buildings, the floor preparation company may also need to conduct a test for hazardous materials, such as asbestos-containing adhesives or lead-based coatings, especially if the floor is several decades old.. These tests are not merely discretionary courtesy; they are indispensable safeguards that safeguard both your business and your employees from severe legal and health hazards.
The floor preparation company will furnish a comprehensive written specification that delineates the work to be performed, the apparatus to be employed, the anticipated cost, and the timeline following the survey. Before deciding to proceed, please review this document thoroughly and enquire about any information that is unclear.
Site Preparation and Planning
Following the agreement of contracts, the subsequent phase entails meticulous business operations planning. A professional floor preparation company will collaborate with you to arrange the work in a manner that minimises disruption, whether that entails phasing the project across sections of the floor, working overnight, or concluding the job over a weekend shutdown. In this phase, it is imperative to maintain transparent communication regarding the duration of each phase and the appearance of the floor during the interim. A competent contractor will adhere to this policy.
The area must be cleared of all racking, equipment, apparatus, and other items prior to the commencement of work. Liability for damage to items left in the work area can become a contentious issue if not clarified in advance. Therefore, the floor preparation company will provide you with guidance on the specific items that need to be relocated and by whom. Particularly in premises that are partially operational during the project, temporary barriers, warning signage, and particulate suppression measures will be implemented.
The Removal of Antiquated Coatings
The removal of an existing industrial coating is rarely a simple process, and the methods employed will differ based on the type and thickness of the coating, its current condition, and the nature of the substrate below. The most suitable technique, or combination of techniques, will be chosen by a skilled floor preparation company to efficiently remove the old surface without causing unnecessary harm to the concrete beneath.
One of the most frequently employed techniques in the industry is shot blasting. It entails the rapid propulsion of small steel abrasive granules across the floor surface, which effectively removes the coating while simultaneously cleaning and profiling the concrete. Built-in hoover systems collect the spent abrasive and debris, ensuring that the machinery is comparatively clean in comparison to older methods. Additionally, the machinery is largely self-contained. In regions where shot blasting equipment is not readily accessible, such as along walls, in corners, or on irregular surfaces, a floor preparation company may employ grinding, which involves the use of diamond-tipped discs.
Scarifying, which involves the use of rotating flails or cutters to mill away the surface layer, may be implemented in situations where coatings are particularly thick or where raised contaminants, such as adhesive residue, require more aggressive removal. Planing is employed in more severe situations where a substantial amount of material must be removed from a large surface area. The floor preparation company will provide a detailed explanation of the methods that are most suitable for your specific circumstance, as well as the rationale behind them. This will ensure that the approach is customised to your floor, rather than relying on the equipment that is currently on the van.
Substrate Repair and Surface Profiling
Removal of the outdated coating is only one component of the task. The floor preparation company will conduct a comprehensive evaluation of the exposed concrete after the surface has been stripped back. Hollows, fissures, laitance, or delamination that were previously concealed beneath the coating must now be addressed before any new finish can be applied. In numerous instances, areas of damage become apparent only after the old finish has been removed.
Surface profiling, which involves obtaining the appropriate texture and roughness on the concrete, is an equally critical component of the process. In order to ensure proper bonding, the majority of industrial coatings necessitate a specific surface profile, which is quantified through the use of comparable standards that specify the depth and texture of the prepared surface. Regardless of the quality of the new finish, premature failure may occur if the substrate does not satisfy the profile requirements specified by the coating manufacturer. Consequently, the floor preparation company will ensure that the substrate complies with these conditions.
Substrate repairs typically involve the application of skim coats or cementitious overlays to level areas of substantial unevenness, the grinding down of high spots, and the filling of cracks with appropriate repair mortars. The floor preparation company may also suggest the application of a moisture suppressant primer prior to the application of the primary coating if moisture readings continue to be elevated. These remedial measures are not optional features that can be compromised; they are essential for the durability of your new industrial floor.
Environmental Factors, Noise, and Dust
The level of disruption caused by floor preparation work is a common concern among business proprietors. Dust and commotion are inevitable to a certain extent; however, a professional floor preparation company will implement all feasible measures to manage and restrict them. Modern preparation equipment is equipped with industrial vacuum extraction systems that are specifically designed to capture the majority of airborne dust at the site of generation. This is especially crucial in environments such as food production, pharmaceuticals, or healthcare, where contamination is a significant concern.
The noise levels will be contingent upon the extent of the area being prepared and the machinery being used. The floor preparation company should provide clear guidance on noise levels in advance so that you can inform staff, residents, or any other relevant parties, as shot blasting and grinding equipment can be loud. In order to comply with local environmental regulations or tenancy agreements, work may need to be restricted to specific hours in sensitive environments.
The current waste management legislation must be followed in the disposal of refuse that results from the removal of surface debris and coatings. If hazardous materials are detected during the survey, the floor preparation company is required to possess the requisite licenses for the transportation, disposal, and handling of this refuse. You should request copies of all pertinent documentation for your own records.
Handover and Final Inspection
After the preparation work is finished, the floor preparation company should conduct a final inspection with you before transferring the surface for coating. This walkthrough provides you with the opportunity to address any apprehensions, verify that the restorations have been satisfactorily executed, and verify that the surface profile and cleanliness adhere to the specifications that were established at the outset. The company is required to furnish you with written documentation of the sign-off process, as well as, if applicable, records of moisture readings and pull-off test results, following the preparation. Not only is this documentation crucial for your own comfort, but it may also be necessary for the coating contractor or manufacturer to verify any warranty on the finished floor.
Employing a floor preparation company is an investment in the long-term efficacy of your industrial floor. The outcome of a professionally and transparently managed process is a substrate that is prepared to receive a new coating of the highest quality. This will provide your business premises with a durable, secure, and visually appealing floor that will be of great service for many years to come.
