How to Repair Damaged Plaster

Tools

Cold chisel, hammer, utility knife, soft bristle paintbrush, 10” wallboard knife and 150 grit sandpaper.

Materials

Latex bonding agent, mortar cement, joint compound and interior primer.

Method

1. Make sure that there are no leaks in the area of the dam aged plaster. If there are any, fix them and allow to dry for a couple of weeks or after next rainstorm.

2. Prepare the room for work by protecting the floor with a plastic cover, take all the paintings off the wall and remove furnishings. Remember to tape around the doors to minimize the dust throughout our home.

3. Gently chip away at the damaged plaster using a cold chisel and a hammer.

4. Using a utility knife, cut along the chipped inside of the edge until the edge becomes smooth and straight.

5. Using a wide, soft bristle paintbrush, apply latex bonding agent onto the edges of the hole and onto the lath.

6. Apply 1 cm (in thickness) of mortar mix using a 10” wallboard knife. Remember that the first layer needs to be cross-scratched when it begins to set; this will help the second layer to stick better.

7. Allow 24 hours to dry.

8. Spray the first coat with water and using the same knife, apply ½ cm (in thickness) of mortar cement of the second coat and remember to cross scratch.

9. Leave to dry overnight, 12 hours minimum.

10. Using the 10” knife, apply the joint compound. Swipe the compound towards the edges evening it with the rest of the wall. Allow to dry for 24 hours.

11. Wet sand the area using 150 grit sandpaper until the area becomes completely even.

12. Using the soft bristle brush to apply a coat of interior primer and allow drying for 4-5 hours.

Complete the project with the final coat of paint.

Furniture Finish Damaged

Problem: Furniture has been blemished with water spots or rings, burn marks from cigarettes, or minor scratches.

Background: Almost any furniture that is used regularly suffers an occasional nick, scratch, burn, or water spot. Though a number of commercial products are available to correct minor defects, furniture-finish ex pert Homer Formby suggests many alternative home remedies, many which use products you probably al ready have in the house.

What to do: To treat water spots and rings caused by moisture trapped underneath wax, try applying tooth paste. Squeeze it onto a wet cotton rag and buff the spotted area. For stubborn areas, combine toothpaste in equal parts with baking soda, an other gentle abrasive. Buff until the spot disappears. Then with a clean cloth continue buffing until you can see yourself. For burn marks, such as those caused by cigarettes, try using nail polish remover. Dip a cotton swab into the remover and rub it lightly across the burn mark. This dissolves the black residue. If any burn mark remains, scrape it gently with a small knife. If a slight hollow remains, mix equal parts remover with clear nail polish and apply 1 coat at a time with the nail polish brush. Let each coat dry between applications (it might take up to 8 coats or so).

Special advice: For minor scratches or other mars on furniture, try using a color crayon which matches the finish. Melt the crayon over the scratch until it flows over the mar, let it cure for half an hour, then gently shave off the residue with a credit card. You can melt the crayon with a soldering iron. Or if you don’t have a soldering iron, tie a nail to a pencil, heat it over a flame, then put the nail to the crayon.

Helpful hint: To mask the musty odor in antique furniture, you can use red cedar shavings (not western cedar). Put the shavings in the toe of an old pair of nylons, tie the end, and cut off the excess. Then tack the sack along the back of the drawer or, if there are no drawers, on the back of the furniture or underneath it.

Building Up Damaged Concrete Surfaces

Building Up Damaged Concrete Surfaces

Painting tips & tricks

Clean the area with T.S.P General Household Cleaner and rinse well. While still damp from washing apply a concrete adhesive (Weldbond) to the entire area. Mix the Bonded Topping mix to a thicker consistency (like muffin mix) and trowel over the prepared area. Texture the surface with a broom if that look is desired. Allow to cure for 24 hours, and then follow with the brightening concrete procedure. Leave for one week and seal with a solvent- based concrete sealer.

For severely damaged surfaces I would suggest hiring a Concrete Restoration service to place a new layer of concrete minimum of 1 ½” over the existing surface. If concrete is sinking in some areas I recommend using a Slab Jacking service to lift and stabilize the slab.


Benefits Of Latex Paints

The benefits of latex paints are:

• No or low odor.
• Quick drying.
• Easy application.
• Easy clean up.

Some interior latex paints also are splatter resistant.

Other pluses: Latex paints are more durable and have increased resistance to blistering and bubbling.


BAGGING

This technique creates a strong, textured look, Prepare the surface with a coat of matte oil- based paint, and working in sections of approximately 2 sq yds (2 sq m), paint on the tinted oil glaze. Place a rolled-up cloth in a plastic bag and run the bag over the surface in a pattern, such as overlapping circles. Wipe off any excess glaze from the bag. When the glaze is dry, protect it with a layer of matte varnish.


Avoid Painting In direct Sunlight

When painting outdoors it is important to follow a few easy steps in order to avoid, “Lap” marks which will show after the paint is dry. Latex paint has a molecular structure which allows vapors to pass through it, which prevent blistering. However, these same properties cause the paint to dry very quickly, especially on hot days, or in direct sunlight. It is best to paint your siding, or foundation in long runs across the house, a few layers at a time, rather than to paint section by section. You won’t see the lap marks until the paint is completely dry, but they will be there.


Asphalt Sealer Coating

Do not work in the sunshine, the best time would be evening or early morning shade.

Do not power wash.

1. Clean with T.S.P General Household Cleaner, heavy-duty mix. For any cracks or puddle areas, fill with premixed asphalt patch. Tamp in place with metal tamper.

2. For small cracks, use premixed asphalt crack repair.

3. Then apply asphalt sealer (not acrylic sealer) with a driveway brush, squeegee or 50 mm roller.

4. In the following years, clean with T.S.P General Household Cleaner and then seal with an acrylic sealer as needed.

Note: Never seal asphalt the first year, let the product cure and Harden.


Cheque Before Painting A Metal Roof

Most people know about galvanic action, the corrosive effect that occurs when incompatible metals come into contact. But few people are aware of the damage to galvanised iron gutters and downpipes that can occur when an old roof is replaced with Zincalume, glazed tiles or painted metal sheeting. These materials, unlike roofing of galvanised steel, unglazed tiles or fibro, do not deposit metal salts and minerals as a protective coating on the inside of the gutter. Pure rainwater flowing from a chemically-inert roof may wash away the protective film on the inside of the galvanised guttering, causing rapid early gutter failure.
