How to repair a minor crack in concrete – How to fill a gap in concrete – How to repair a small hole in concrete

How to repair a minor crack in concrete:

1. Clean the area so that it is free of debris. You can sweep it out, or use a wire brush or vacuum it out with a shop vac. It must be dry before you move to step 2.

2. Apply caulk into crack. Use an ample amount of caulk to fill the crack to just above the surrounding surface.

3. Take a trowel and smooth out the caulk so that it is level with the surrounding area. If the crack is small enough, you can use your finger to smooth out the caulk (make sure to wear a rubber glove).

4. Let dry for at least two hours.


How to fill a gap in concrete:

1. Make sure the area is dry and clear of debris.

2. Take caulking and apply it to the entire length of the gap. Use generously

3. You can even out the caulking with a glove-covered finger, a trowel, or the back of a spoon rubbed with oil you can use any oil—baby vegetable, olive, even suntan oil.

4. let dry for at least 4 hours.


How to repair a small hole in concrete:

1. Break away any loose or unstable material. The easiest way to do this is with a small chisel and hammer.

2. Clean up any excess debris. If you can use a shop vac, it’s best. Make sure area is dry

3. Use a paintbrush to apply the bonding adhesive to the entire area that needs to be patched.

4. Fill the area with the reinforced patching compound, only adding about ‘4 inch at a time.

5. Wait about 30 minutes for the layer to dry.

6. Apply additional layers until you have filled the hole to just above the surrounding surface area.

7. Use a trowel to smooth out the area being repaired, until it is level with the surrounding area, its okay to let the mixture feather over the surrounding area to get a good, level base.

8. Allow the mixture to cure (or dry). Although it will take months to completely cure, you will begin to see hardening within the first few minutes, and it will be hard enough to walk on within 2 hours.

How to repair a crack or hole in plaster

How to repair a crack in plaster:

1. If the crack is large, the first thing you want to do is make it bigger. What? Isn’t that more work? No, trust me. You want to extend your work area to make the repair last. If you just fill in the crack, it will come right back Make the crack larger with a utility knife.

2. Then clean the area around the crack. Scrape off any loose plaster or wall texture around the crack. Apply a thin coat of joint com pound in the crack, letting it feather out over the crack.

3. Take fibreglass tape and cover the entire crack. This tape allows for mobility so that future cracks can be avoided.

4. Apply a thin coat of joint compound with a wide dry wall knife, much like you would frost a cake, until the tape is completely covered and smooth.

5. Allow a couple of hours to dry.

6. Take fine sandpaper and smooth out the compound when completely dry.

7. Apply as many coats as necessary to assure that the crack and tape are completely covered and appear to be smooth and flush with the wall. Allow each coat to dry properly.

8. Try to recreate the texture of the wall. Do this by put ting a small amount of joint compound on a wet wash cloth. Dab it onto the wall like you would a sponge, until you have closely matched the surrounding texture, adding or subtracting wherever necessary if you have a smooth wall, just leave it smooth.

9. You are ready to prime. Make sure you use a primer before you paint because the new substance on the wall is much more porous and will absorb paint more quickly, changing the color and texture of the paint slightly.

10. Allow two coats of primer to dry before applying the paint to match the wall.


How to repair a hole in plaster:

1. Smooth out the edges of the hole with a utility knife.

2. Clean all debris from area. Make sure area is dry.

3. Brush concrete bonding agent onto the wood (lath) and old plaster surrounding the hole.

4. Attach wire mesh to the existing wood (lath) with dry wall screws. Why? Because, like the tape when you are fixing cracks, the wire mesh creates a surface that the joint compound can adhere to.

5. Fill in the hole with joint compound and smooth the outermost portion with a wide drywall knife to just below the surface of the surrounding area.

6. Where the compound meets the old edge, apply fiberglass mesh tape. You will basically be making a square box around a round hole.

7, Apply a thin coat of joint compound with a wide dry wall knife, much like you would frost a cake.

8. Allow a couple of hours to dry.

9. Apply as many coats as necessary to assure that the hole and tape are completely covered and appear to be smooth and flush with the wall. Allow each coat to dry properly.

10. Take 100-grit or similar sandpaper and sand over the joint compound until smooth.

11. Try to re-create the texture of the wall. Do this by put ting a small amount of joint compound on a wet wash cloth. Dab it onto the wall like you would a sponge, until you have closely matched the surrounding texture, adding or subtracting wherever necessary.

12. You are ready to prime. Make sure you use a primer before you paint because the new substance on the wall is much more porous and will absorb paint more quickly, changing the color and texture of the paint slightly.

13. Allow two coats of primer to dry before applying the paint to match the wall.

Hole or Crack in Plaster


Problem: A hole or crack in plaster walls or ceiling needs repair.

Background: Two types of patching compounds are available: 1) spackling compound which is convenient for small jobs and can be bought as powder or ready mixed, and 2) patching plaster which can be bought in larger packages and needs to be mixed with water. For repairing holes or cracks in the wallboard.

What to do: Both small cracks and holes can be filled with patching mixture; large holes may need to be filled step-by-step. First remove any loose plaster. Then use a knife to scrape out the plaster from the back of the crack so that the back is wider than the front surface. Thoroughly dampen the surface of the crack with a wet cloth or paint brush, mix up a small amount of patching com pound and fill in the crack with it. Smoothen the surface with a putty knife and sand the patch area after it has dried.
For larger holes or cracks, fill the hole partially and allow it to dry as a base for a final fill. Then add a second batch of compound. Let dry and sand until smooth. For large holes, you may need to fill in the area be hind the crack with wadded news paper. Begin patching by working inward from all sides. Let dry, then apply another layer around the new edge. Repeat until the hole is filled. Allow to dry and sand smooth.

Special advice: If the surface be yond the repair is textured, you can attempt to match the surface of the patch while the plaster is still wet. A sponge, comb, or other device can be used to accomplish the texturing.

Helpful hint: To sand repaired areas, it can be helpful to wrap sandpaper around a small length of wood. This will help keep the surface even. To check for ridges, hold a trouble-light or lamp next to the wall on one side or the other.

Concrete crack repair

Painting tips & tricks

Concrete crack repair

First determine if the crack is severe enough to repair.

If only a hairline crack, my recommendation is to leave it as is, since patching will only make it look worse.

If the crack is 1/8” or greater, the following would be the best remedy.

Note: If the crack has been caused by unstable substrate under the slab from poor compaction, my recommendation would be to have a slab jacking service (if available) come to your rescue and stabilize the slab before repair-

Clean entire surface using T.S.P General Household Cleaner, or a suitable exterior cleaning solution.

Tuck into crevice a foam backing rod (available in 1/8, 1/4” – 3” diameters) setting it down into the crack ½” from the surface.

Apply Weldbond or concrete adhesive over foam backing rod. Allow to cure for 1-2 hours.

Apply polyurethane caulking (gray or concrete colour) into crack crevice.

Sprinkle dry sand over caulking and brush excess off using a paintbrush.

Allow to cure for 12 hours before using area.

Choices for Wood Siding

Exterior wood siding can be painted or stained. There is a wide array of products available in both mediums. I prefer an alkyd (oil base) primer for bare wood, the top coat would vary depending on the look desired.

Primer is not required under stain except solid color stain that is white or another light color.

For repainting, primer is only required for areas where the preparation steps brought you down to bare wood, or where stain killer is needed due to mildew or water damage.

Stains for wood come in several degrees of transparency. Semi-transparent stains are useful for letting the wood grain show through, that can be a very nice look over cedar shingles.

Painting Tips – Cleaning Up

If you are planning to continue the work the next day, just keep the paint and roller in the paint tray and cover with a tray lid or cellophane. The next morning run the brush or roller over a newspaper a few times and it will be ready to use.
After the job is completed wash the rollers and brushes and paint tray with water. Do not use a spinning tool to clean brushes as this will make your brush flare. Wrap the clean brushes and rollers with newspaper and secure with a rubber band. Store the brushes flat or hang them on hooks.
Excess paint can be stored in the can. If you have no further use for the paint donate it to a charitable institute or in the case of water based paint pour over shredded newspaper or cat litter and throw the paper or cat litter in the trash. If it is oil based paint it cannot be thrown as it is considered a hazardous substance. Make enquiries with you local council as to the best way to dispose of it.

Cleaning Wood Window Frames

If painted, use a solution of mild detergent and water, or a mild commercial cleaner whose label says it is safe for painted surfaces. Always rinse off solution.
Wipe off excess water with a dry cloth. Do not use strong cleaners or scouring powder as these will damage the paint. If you plan to clean window frames, do it before cleaning window glass so solution does not spot glass panes. If natural-finished, vacuum or dust regularly. Clean infrequently, only when really needed. Use a commercial wood cleaning product or cleaning wax whose label recommends use on natural wood finishes.

Color choices for faux finishes

Color tips for techniques:

When using colorwashing, sponging or dragging techniques

A pastel cover of an off-white background will produce a fresh, cheery effect.

A dark color over a light background will give a bold, dramatic look.

Slight variations of the same color will give the surface a feeling of depth.

Common Exterior Uses of Caulk

Filling in the gap between a window and the molding (brick mold) around it.

Filling in gaps where different surfaces meet (such as a foundation and siding).

Filling in holes in the concrete block of a foundation (use masonry caulk).

Use a putty knife to make sure the caulk bonds to the surfaces around it.

Filling in the gap between a sidewalk and foundation.

Common Interior Uses for caulk

Some Common Interior Uses of Caulk

Prevent moisture from getting into gaps between walls, bathtubs, countertops and sinks.

Filling in gaps where different surfaces meet, such as ceramic tile and baseboard.
