Preparation Instructions for Sigmacover 280

Surface Inspection

Ensure the surface is structurally sound and free from damage, and dry. Repair any cracks, holes, or imperfections before starting the painting process.

Surface Cleaning

Thoroughly clean the surface to remove any dirt, dust, oil, grease, or other contaminants. This ensures proper adhesion and a uniform finish. For previously painted surfaces, remove any loose or flaking paint with a scraper or abrasive paper. Glossy substrates should be mechanically abraded to create a key for the new paint.

Degreasing

For areas exposed to oils or heavy contamination, degrease the surface using an appropriate cleaner and allow it to dry completely. Rinse the surface with clean water if necessary and ensure no cleaning residues are left behind.

Moisture Check

Ensure that all surfaces are completely dry before painting. Moisture or dampness may hinder the adhesion and overall performance of the coating. For best results, use a moisture meter to ensure the surface has a moisture content of less than 18%.

Temperature Conditions

Apply the paint when the surface and air temperature are between 5℃ and 25℃. Avoid application in conditions where humidity exceeds 85%, or if there is a risk of rain or frost before the paint has dried.

Masking and Protection

Mask off adjacent areas that do not require painting, such as trim, fittings, or adjacent surfaces, to ensure clean and precise edges. Use protective sheets or covers to shield nearby objects from paint splashes.

Mixing the Paint

Stir the Sigmacover 280 thoroughly with a stick or paddle before use. Continue stirring at intervals during application to maintain an even distribution.

By following these preparation steps, you will ensure a durable finish, ideal for areas exposed to machinery. For optimal performance, always refer to the product’s technical data sheet and manufacturer’s guidelines.

Application Guidance for Sigmacover 280

Initial Coat Application

Using a quality brush, roller, or spray equipment (contact us for further information on spray application), apply the first coat of Sigmacover 280 evenly across the prepared surface.

Coverage

Apply the paint at the recommended coverage rate, which is typically around 5.7 square meters per litre, depending on the texture of the surface. Avoid over-applying the paint, as it may affect drying times and finish quality.

Edge and Detail Work

Use a small brush to carefully cut in around edges, corners, and areas near walls or fixed structures.

Drying Time Between Coats

Allow the first coat to dry for at least 2 hours before applying a second coat. The paint is touch-dry within 2 hours, depending on temperature and humidity. Avoid knocks and scrapes on the freshly painted surface during this drying time to prevent damage to the finish.

Second Coat Application

Apply a second coat of Sigmacover 280 to ensure maximum resistance. Stir the paint thoroughly before application. Follow the same application method as the first coat, taking care to cover any missed areas and ensure a uniform finish.

Post-Application Care

Allow the painted surface to dry for a minimum of 24 hours before handling and using the painted surface. For areas subject to heavy machinery or equipment, wait at least 7 days before use to ensure full curing. Avoid exposing the painted surface to water or heavy moisture for at least 7 days after application to prevent discolouration or poor adhesion.

Tools and Equipment

After completing the application, clean all brushes, rollers, and spray equipment with 91-92 thinner. Ensure that tools are thoroughly cleaned immediately after use to prevent the paint from hardening.

Temperature and Weather Conditions

Do not apply the paint if rain is expected within 24 hours, or if the temperature is below 5℃ or above 25℃ during application and drying times. Protect the freshly painted surface from frost until fully dry.

Final Note

By following this application guidance, you’ll achieve a professional finish that is both durable and effective in high-traffic areas. For additional details on the product and its specific uses, consult the technical data sheet provided by Sigma.

Aftercare for Sigmacover 280

Initial Curing Period

Allow the painted surface to fully cure before subjecting it to heavy use or machinery. While the paint is dry to the touch in 2 hours, full curing may take up to 24 hours depending on conditions such as humidity and temperature. Avoid dragging heavy objects or machinery across the surface during this curing period to prevent damage to the finish.

Regular Cleaning

Clean the painted surface regularly to maintain its appearance. Use a cloth or wipe along with a mild detergent solution. Avoid harsh chemicals or abrasive cleaning tools, as these can damage the paint and reduce its effectiveness. For large areas or industrial settings, power washing at low pressure can be used for cleaning. Ensure that no high-pressure jets are used directly on the surface to avoid wearing away the paint.

Preventing Damage

Heavy impacts or dragging sharp or heavy objects across the painted surface may damage the coating. Use protective mats or padding where needed to minimize wear in high-use areas, especially where equipment is moved frequently. Keep the surface free of debris such as dirt, gravel, or sand that could cause abrasion and premature wear of the coating.

Reapplication and Maintenance

Over time, particularly in areas exposed to machinery, the coating may reduce due to wear. Inspect the surface regularly and touch up any areas that show signs of wear or damage. Reapply a fresh coat of your chosen topcoat over Sigmacover 280 to refresh the appearance. Ensure that the surface is clean and dry before any reapplication.

Long-Term Protection

For exterior surfaces, inspect the painted area after harsh weather conditions such as heavy rain or frost. If water or frost damage is evident, clean and dry the area thoroughly and consider reapplying a fresh coat to maintain durability. If used in an area exposed to oil or chemicals, promptly clean spills to prevent staining or weakening of the paint’s adhesion.

Seasonal Maintenance

In colder months, protect the surface from ice buildup by using non-corrosive de-icing agents. Avoid using salt or other de-icing chemicals that can degrade the paint over time. Regularly inspect areas exposed to the elements for any signs of cracking, peeling, or wear, particularly after winter or periods of heavy use.

By following these aftercare steps, you will maintain the longevity, appearance, and effectiveness of Sigmacover 280, ensuring it continues to provide safe and durable protection on a variety of surfaces. Regular maintenance will also help extend the life of the coating.
