APPLICATION

Dilution rates:

9 parts water to 1 part Sika® Cement & Mortar Stain Remover – Cleaning general stains and ingrained dirt from paths, patios and horizontal surfaces.

2 parts water to 1 part Sika® Cement & Mortar Stain Remover– Cleaning light mortar stains from paths, patios, walls or vertical surfaces.

1 part water to 1 part Sika® Cement & Mortar Stain Remover – Cleaning heavy mortar stains from walls or vertical surfaces.

Neat – Cleaning tools, cement mixers and other construction equipment.

General Cleaning: Pre-wet surfaces with water and apply Sika® Cement & Mortar Stain Remover with brush or low pressure spray (avoiding mist formation) from the top of the area downwards for vertical surfaces. Leave for 5-10 mins then scrub/wash off with a hose, brush or power washer until the surface is clean. Never allow the product to dry on surfaces. Where a second application is necessary, repeat the procedure. Note: For patios and pathways care should be taken and in these cases do not reduce the 2:1 dilution rate above. If in doubt, always test on a small, inconspicuous area before full application.

Cleaning tools/equipment: When cleaning tools and equipment pre-wetting is not necessary. Sika® Cement & Mortar Stain Remover will remove fresh cured cement and wet or semi-cured cement from tools. For light stains soak items for approx. 1 hour or up to 3 hours for heavy deposits. After soaking, rinse thoroughly with clean water. Use of a scourer will assist removal of stubborn stains. Use a hot power wash to assist removal of staining from mixing equipment. After removal, always spray tools with All Purpose XT44 Maintenance Spray (or any other proprietary maintenance spray) to prevent further corrosion/rust.
