How to Parge a Concrete Block Wall, SAKRETE Parging Mix, Hunker, Home Guides, and SF Gate are some of the other websites.
Cinder-block walls or foundations can be unattractive.A smooth, even appearance over the wall is created by parging.Portland cement, sand and other materials are parging.The cement can be applied up to 2 inches thick, but a 1/2 inch coat is sufficient.Before you apply the material, you need to remove paint and tar from the wall and make small cracks to allow the parging cement to adhere.

Use a hand grinder to remove paint, glue, and tar.The spinning disk should be run over the tar or paint if you hold the grinder at a 45 degree angle.Don't press the disk into the wall and let the grinder do the work.Wear safety glasses and a dust mask to protect your eyes from flying debris and harmful concrete dust.
Use the cutting edge of the disk grinder to cut vertical cracks on the wall.When adhering to the wall, the cracks give the parging material something to grasp.
The nylon-bristled brush can be used to remove debris from the wall.Spiders and other insects can create messy webs on the underside of the house siding.All this material should be brushed away.
Drop cloth over the floor or ground to protect it.Put water in a bucket.
The sand/topping mix should be mixed with water.Slowly add water to the wheelbarrow from the sand/topping mix.Make sure that the water is fully mixed in before you add more.There is a 60-pound bag of sand/topping mix.Only mix as much parging material as you can in 20 minutes if you are working alone.If you take too long to apply the sand/topping mix, it will create pebbles that abrade your smooth surface.
The sand/topping mix needs to be tested.The mix should look like mud.The mix is ready if you can make a letter "M" or "S" in it.
Dunk the nylon-bristled brush in the bucket of water and spread the water over the wall.It is best to start at the bottom of the wall and work your way up to the top.
Press the mix to the wall with the pointing trowel.Spread it evenly over the wall and overlap the edges.To keep the wall moist, mist it from time to time with a spray bottle.
Apply more parging mix after brushing water onto the wall.If you want to smooth over the section with the trowel, lightly mist the entire section.The final action smooths your pointing-trowel strokes and creates a clean and polished surface.
