Methods

To remove dirt and dust:

1. Add 100 to 200 grams of trisodium phosphate in 4 liters of lukewarm water.

2. Apply this solution on the surface with an insecticide sprayer starting from the bottom to avoid runs.

3. Rub surface vigorously and let the solution work for 2 to 3 minutes.

4. Rinse the surface with a spray of clean pressured water. To keep from damaging wood surfaces, pressure should not exceed 3,400 Kpa (500 psi). Maintain the spray nozzle 30 cm or less from the surface for the treatment to be fully effective.

5. Repeat as needed.

6. Let the surface dry.

7. If the sealant is cracked or is not restored to its original look, remove it by cutting it along the surface, then scrape off any residue. The degree of humidity on the surface should be lower than 12 %. If the surface is in wood, make sure it is properly painted, stained or waterproofed.

To remove wax, soap, grease and oil:

1. Add 200 grams of trisodium phosphate per liter of warm water.

2. Apply the solution on the surface with a stiff bristle brush.

3. Rub surface vigorously starting from the bottom to avoid runs.

4. Let the solution work for 5 to 10 minutes.

5. Rinse the surface with a spray of clean pressured water. To keep from damaging wood surfaces, pressure should not exceed 3,400 Kpa (500 psi). Maintain the spray nozzle 30 cm or less from the surface for the treatment to be fully effective.

6. Repeat as needed.

7. Let the surface dry.

8. If the sealant is cracked or is not restored to its original look, remove it by cutting it along the surface, then scrape off any residue. The degree of humidity on the surface should be lower than 12 %. If the surface is in wood, make sure it is properly painted, stained or waterproofed.

BLEACH (NOT MANUFACTURED BY SICO INC.)

Introduction

Bleach is a non-flammable product useful for eliminating mold that causes mildew. It bleaches and disinfects, but does not remove grease. To get rid of grease, use trisodium phosphate (T.S.P.).

Never mix T.S.P. and bleach directly because the mixture will produce toxic fumes.

Checklist

Method

Removing mildew:

1. Pour 1 liter of bleach and 3 liters of warm water in a bucket or insecticide sprayer.

2. Apply this solution on the surface starting from the bottom to avoid runs.

3. Rub the surface with a stiff bristle brush or a scouring sponge.

4. Let the solution work for 5 to 10 minutes.

5. Rinse the surface with a spray of clean pressured water. To keep from damaging wood surfaces, pressure should not exceed 3,400 Kpa (500 psi). Maintain the spray nozzle 30 cm or less from the surface for the treatment to be fully effective.

6. Repeat as needed.

7. Let the surface dry.

8. If the sealant is cracked or is not restored to its original look, remove it by cutting it along the surface, then scrape off any residue. The degree of humidity on the surface should be lower than 12 %. If the surface is in wood, make sure it is properly painted, stained or waterproofed.

POLYPREP 875-104 AND 875-105 THINNERS

Introduction

Polyprep 875-104 and Polyprep 875-105 thinners are flammable products used to clean tools involved in applying paint and sealants such as paintbrushes, rollers, spray devices and trays. They are also used to reduce the viscosities of solvent-based coatings when needed. Finally, they can remove grease, oil and tar.

Polyprep 875-104 and 875-105 thinners are colorless and Polyprep 875-105 thinner has very little odor. Polyprep 875-105 thinner is thus the best choice if thinner odor poses a problem.

Put on rubber gloves before using thinners. Avoid breathing fumes and make sure thinner does not come in contact with skin or eyes.

Checklist

Method

Removing grease, oil and tar stains:

1. Remove as much contaminant as possible from the surface.

2. Pour a little thinner on a clean, lint-free rag.

3. Rub the surface with the damp rag and let the surface dry.

4. Wash the surface with clean water.

5. Rub the surface with a clean, dry, lint-free rag.

6. Repeat as needed.

7. Hang up the rag so the thinner can evaporate and thus prevent risks of fire.

8. Let the surface dry.

9. If the sealant is cracked or is not restored to its original look, remove it by cutting it along the surface, then scrape off any residue. The degree of humidity on the surface should be lower than 12 %. If the surface is in wood, make sure it is properly painted, stained or waterproofed.
