Do I Really Need A Concrete Grinder
There are many different types of concrete grinders on the market. What you plan to do with a concrete grinder will have a lot to do with whether you need one and how you will use it.
A concrete grinder is used for a number of reasons such as removing things like paint spills, glue, imperfections in concrete work, smoothing uneven surfaces, removing formwork seams or protrusions. Each concrete grinder has built-in features and can be used for some or any of the above applications. One of the most important features to look for when deciding to purchase or use a concrete grinder is a dust collector or vacuum. The reason this is so important is because you will lessen the amount of dust you are breathing in and have less mess after the job is completed, making clean up a lot quicker. Most models should have a dust collector, even small hand held concrete grinders.
Some of the types of concrete grinders available are:
*Shrouded concrete grinder with vacuum. This particular grinder is used for cleaning of planning and removal of glues and paints from concrete work. It is also ideal for smoothing uneven surfaces. The three different sizes available are 5, 7 and 10 inch models. A dust vacuum is used to stop dust and help remove debris while you are working.
*Heavy-duty grinders. 7-inch heavy duty angle grinders for concrete applications are made especially for concrete work. They are mainly used for removing blemishes or cleaning the concrete surface. Make sure there is a dust collection device included with the model.
*5-inch concrete surface grinder. This model will refurbish and deburr concrete, remove irregularities, form-work seams and any protrusions. There is a built in dust chute with most models that will remove dust and debris. This type of concrete grinder only weighs 6 pounds, making it ideal for reducing worker fatigue.
*Hand held grinders. These are ideal for small jobs like areas close to walls and other hard to get places. They are also ideal for removing blemishes to concrete work. They are very light and easy to use. If you have a large area to cover, a hand held grinder may be a little impractical.
*Multi headed grinders. These models come with dust collectors and are designed for large areas. Their main purpose is to level and remove small imperfections to concrete work. The brushes used in multi headed grinders can be changed to suit the surface.
When choosing a concrete grinder, the first thing to consider is what you are planning to use it for and the size of the job you will be doing. If you are only using a large industrial grinder once it may be a cheaper alternative to rent a machine. If you only need a small hand held concrete grinder, it may be a good idea to buy one.
