Wedge anchors or masonry anchors are designed to be completely fixed into the concrete. Masonry anchors work in two ways - either by using concrete friction to hold in place or by gripping the concrete walls. Masonry anchors can have many types including: zinc plate anchors, screw holder, hammer wedge, etc. The removal of these anchors can be done by following simple steps.

Step 1: Taking Precaution & Preparing Yourself

It is very important to take precautionary measures while doing masonry work. Make sure that you wear the protective gloves and safety goggles along with the nose mask. The instruction manuals which come along the electric saw and drill should be properly read. Wear old clothes to avoid the fear of staining. Make sure that all the doors and windows are open to create a well ventilated space. 

Step 2: Removing the Base Plate

Now take a pry bar and hammer it along the sides of the base plate at an angle. Once the pry bar is fitted in between the wall and the base plate, start to pry open the anchor plate. Use all the force you can to open the base plate. You can also hammer the bar to push open the base plate. This might take out some concrete of the wall, do not worry we can always cover the opening using cement or plaster of Paris.

Step 3: Chiseling & Drilling

If the base plate is not coming of the wall you can use a hammer and a chisel to break open the concrete surrounding the base plate. Make sure that your goggles are on your eyes before doing this as small tidbits of concrete might get into your eyes. Alternatively holes can be drilled around the base plate with electric drill and the pried open as in step 1.

Step 4: Filing of the Edges

Sometimes in spite of hammering and drilling, the anchor plate might leave the bolts in to the wall. These can wither be sawed off using an electric saw. After sawing of the ends filing of these metallic bolts can be done using a filer. This helps in achieving a smoother finish and leaves the bolt in the wall without its head.

Step 5: Finishing up the Wall

Most of the concrete in the wall would be either chiseled out or pried open leaving a hole in the wall. This opening should be covered using cement or plaster of Paris. This should be done by mixing water and cement or plaster of Paris in 2:1 ratio and then mixed properly. It should be applied to the wall and should be leveled. This part has to be left to dry and cured for 2-3 days before painting it.
