Best Concrete Polisher Buyer’s Guide

The best way to polish concrete

The concrete polisher is used to finely grind and smoothen concrete surfaces so as to achieve a high-gloss finish. Using one of these tools is considered to be the best way to polish concrete. It is also the fastest and most efficient way.

The glossy finish achieved when using a concrete polish can retain its shine without waxing or coating it.

This makes concrete polishing the most economical alternative to flooring the surface with pricey granite or marble so as to achieve a mirror-like finish.

Polishing ensures that the concrete surface achieves a smooth and shiny finish. It therefore has a decorative value, with the degree of decorative shine on the surface determined by the type of polishing pad used.

Different types of polishing pad

The 3 main types of polishing pads used with concrete polishers are the soft pad, the rigid pad, and the dry/wet pad.

Soft pads use a rubber backer to attach onto the polisher disc, and they can polish contoured surfaces well.

Rigid pads are attached to the polisher disc using a quick-release mechanism, and they polish much quicker than soft pads though they can gouge surfaces if the pads are not held absolutely flat.

The dry/wet pads are designed to fit onto high-speed angle grinders and use quick-release mechanism to attach onto the grinder disc.

The daily grind

The polishing process can be preceded by concrete grinding. Grinding flattens the concrete surface, as well as cleans it of hardened grit.

This leaves behind a flat concrete surface that is ready for polishing. Thereafter, a grit pad (usually the lowest pad of 60 grit) is fitted onto the polishing disc in readiness for the first stage of polishing.

All about the finish

There are three grades of concrete finishing. When well-prepared concrete mix is poured properly onto its mold or onto the surface, its top-most layer settles into a cement paste which gradually forms a uniform layer as it dries, and then acquires a uniform solid color.

When it dries completely, it produces what is called a cast finish. When this cast finish is polished very lightly, the cement layer is gradually pared down to reveal the fine sand embedded in the concrete matrix, and this grade of finish is described as light finish.

If the polishing process continues, the rock aggregate in the concrete matrix is exposed, and this grade of finish is described as the ground finish.

Using a concrete polisher

The thickness of the layer removed from the cast finish till the ground finish is achieved is normally 1/16 (0.0625) inches.

This can be achieved using a variable-speed concrete polisher fitted with diamond sanding disc(s). generally, a 60-grit sanding disc (pad) is used to create a ground finish, while a 3000-grit pad is used to create a light finish.

Water cooled operation

Generally, concrete polishers are water-fed and this necessitates them to have a universal fitting that can accept standard water hose connections.

Water is used to cool the pads of the polisher as well as minimize dust generation. However, the use of water does raise minor safety concerns.

Because concrete polishers are electrically-powered, the use of water to cool its pads raises the possibility of electrocution if the polisher is not well grounded, and for this reason it is recommended that one acquires a polisher that has a Ground-Fault Circuit Interrupter (GFCI).

Even so, the worker still needs to wear rubber gloves as an added safety precaution.

Likewise, the worker must wear a fully-working particle mask so as to prevent the caustic concrete dust from irritating your face, airways and eyes.


Best Concrete Polisher – Top 5 Reviews

There are different types, models, variants, and brands of concrete polishers and it is sometimes difficult to compare them based on their work output alone.

For this reason, specific criteria are used to rate concrete polishers, and these criteria are cost-performance ratio, finish quality, product design quality, ease of maintenance, safety profile, and ease of use.

Using these criteria, 5 of the best concrete polishers have been selected for review. Among these 5, the best concrete polisher is singled out and identified appropriately as our top pick choice below.

1. TOP PICK: Makita PW5001C Concrete Polisher

This is a versatile and high-quality hand-held, single-disc concrete polisher that is powered by 127-volt AC power.

It is well suited for wet stone polisher and comes with a 4-inch electronic wet-stone Polisher (model number PW5001C-R) and a well-fitting head cover (model number 417322-5).

This concrete polisher is made by Makita Tools, a U.S-based franchise of the globally renown power tools manufacturer, Makita Corporation.

The Makita PW5001C has a compact design with a cylindrical body onto which is fitted a (rectangular) cuboid polishing head unit.

The polishing disc is attached to the underside of this polishing head unit. This lightweight polishing machine weighs 8.4 pounds, and measures 16 inches in length while its square-like cross-section measures 6 inches by 5.5 inches.

The compact ergonomic design of this concrete polisher makes it an easy-to-use device, with its durable housing encasing its internal components, including the industrial-grade die-cast aluminum gear system.

Its common fittings allows popular water hoses to be connected to the polisher, with 3 holes located at the top of the spindle allowing water to be spread evenly onto the pad hence ensuring that the pad does not clog.

There is also a side handle, which allows the user to have a steady grip on the polisher. However, its front handle does not flip-up and this prevents the worker from getting the head unit of this polisher into tight spaces over-head.

The polishing disc used on the Makita PW5001C is 4 inches in diameter, and can achieve a load-free speed of 4,000rpm within the first minutes after the polisher is turned on.

The water feed valve connected to the common fitting of the polisher is made of solid brass, and this allows it to control rate-of-flow for a long time without developing rust or being corroded.

The PW5001C is electrically-powered with a 7.9 amperes AC motor under the hood. This is able to deliver an impressive maximum disc spinning speed of 4,000 revolutions-per-minute(rpm).

The speed dial allows for speed control within a range between 2,000rpm and 4,000rpm. The resulting electronic speed control allows this polisher to maintain constant speed regardless of its load.

There is also a soft-start feature which allows the polisher to achieve smooth start-ups.

The electric cord that routes power from the 127-volt AC power socket to the 7.9amp motor, emerges from the cylindrical body of the polisher and terminates into a GFCI plug.

There is also an overload switch protects the armature of the motor from failure during periods of high current supply (overloads).

The most unique aspect of the Makita PW5001C is its hook-and-loop feature which allows accessories and other attachments to be easily fitted onto the polisher.

The motor weighs a mere 5.1 pounds, which enables this polisher to have a high power-to-weight ratio (about 1.72) that minimizes the degree of operator fatigue during use.

The polisher is shipped alongside a 4-inch wet-stone polisher, head cover, rubber pad, wrench, dust cover, and an easy-to-follow operating manual.

Moreover, Makita Tools provides a 12-months warranty for this model.
