HTC examines why grinding combined with H class dust extraction is the best method to level a surface for floor preparation.
DONE AND DUSTED
Thanks to grinding, removal of old floorcoverings, leveling out of underlying concrete surface and the creation of the perfect surface for further treatment of your floor is all completed in one action.
Smarter working methods improve working environments, in the modern world sustainability and environmentally-friendly options are as important as productivity. Due to the nature of grinding these efficiencies are clear.
DUST-FREE ENVIRONMENTS Many construction activities, such as grinding, produce large quantities of dust including materials containing silica and gypsum. These need to be controlled to ensure as safe and workable environment as possible.
It’s advisable to utilise a vacuum that meets requirements laid out by the HSE to prevent the inhalation of dangerous particles found in both concrete and other removable surfaces. Respirable size fractions, uncontrolled, can cause exposure exceeding UK occupational limits so vacuums with the best suction capabilities and filters that meet these requirements are key. The new HTC series includes a complete range of dust extractors offering best in class suction rates as well as exemplary safety features including H class filters.
All new HTC vacs feature the three-step filtration process with Longopac-system and are in compliance with the highest international standard “H” (IEC-60335-2-69, EN60335-2-69) regulations and as such give the best protection from harmful dust and silica for both operator and the public.
The HTC D10 is a light and versatile dust extractor, best suited for handheld grinders and general clean-up. HTC D20 recommended for use with HTC 280 and 450 grinders and other small grinders has two HEPA H13 filters, it can handle the finest concrete dust.
Good results require good preparation. This is especially important when working with concrete floors. Some jobs are

more demanding than others and a floor grinding pro knows what will make the difference.
Effective diamond tools must find the right balance between productivity and life expectancy. A poor tool can cost a lot more than the price tag. Poor tooling with little or non-uniform diamond layering can lead to ineffective performance so the selection of a tool with good manufacturing qualities and standards will undoubtedly reap benefits in the longer term.
Similarly tooling that cannot last the job at hand will increase labour rates and reduce productivity. HTC has focused on developing the latest line of diamond tools expressly for floor prep. Whether it’s a matter of such demanding work as removing old paint or levelling compound so that it can be replaced with a new coating, or levelling a concrete surface prior to grinding and polishing, the choice of tools is crucial for achieving the best final results.
THE PERFECT COMBINATION Ultimately the job at hand when dealing with surface preparation is defined by the sum of the parts. Recommended machine combinations with correct tooling and professional training will deliver a better finished job.
Individually, HTC's machines and tools deliver top results, but it's when they can work together that maximum synergies are attained. Well-proven and robust technology makes your job safer.
Well-optimised dust flow – from the floor under the grinding hood to the H classified dust extractor’s dust bag – protects you from dangerous dust.
Add in HTC's broad assortment of diamond tools of premium quality and you have a concept that will deliver day in and day out.
