PRODUCT INFORMATION

Read entire label and SDS before using. 511 Porous Plus should not be diluted or thinned in any way. 511 Porous Plus should be used, as is, direct from approved container.

NOTE: Always protect neighboring surfaces, including wood, carpet, metal, landscaping and other non-masonry surfaces.

NEW SURFACE

SURFACE PREPARATION 
Surface must be dry and free of contaminants, including previously applied sealers, dirt, lime & hard water deposits, efflorescence, rust and grime.

NEW SURFACE APPLICATION 

• 511 Porous Plus is ready to use. Do not thin. Use only when air (ambient) temperature is between 32-120°F (0-49°C) Do not apply in direct sunlight. For exterior applications, do not apply if rain is expected within 24 hours. Use in a well ventilated area. 
  NOTE: Due to the differences of each substrate, several inconspicuous test patches should be completed to ensure maximum performance. User must determine suitability of the product for their intended use.
• Before Grouting: Apply 511 Porous Plus to the surface only of your substrate prior to grouting. This step will allow quick and easy cleanup after grouting. Grout can stain many surfaces if this procedure is not used prior to the grouting process. Apply 511 Porous Plus using a Miracle Sealants Mira Brush or a clean, lint free rag. Apply enough to wet the surface. Be careful not to saturate the open grout joints. Allow 511 Porous Plus to stand for approximately 3-5 minutes for maximum penetration. All excess must be removed at this time by buffing surface with a clean, lint free rag. This step is very important, as removing excess sealant is necessary for all substrates.
• Allow 511 Porous Plus to cure for 6-12 hours before continuing with the grouting procedure. For very porous substrates apply another application after the previous application has dried 2-3 hours.
• After Grouting: Once grouted, make sure that all grout residue is removed from the surface with a clean sponge and water. Allow grout to fully cure per manufacturer’s specification. If grout clean-up is not performed effectively, an additional cleaning may be necessary to remove remaining grout residue or haze. For this procedure use the appropriate Miracle Sealants cleaner for the grout you have installed: Phosphoric Acid Cleaner, (HDAC) Heavy Duty Acidic Cleaner (Hydrochloric Acid), Miracle Heavy Duty Cleaner or Epoxy Grout Film Remover, following the instructions carefully.
• Once the grout has completely cured, proceed with the sealing of the grout for water and stain resistance. Apply 511 Porous Plus to all (appropriate) grout (some grout will require the use of a water based sealant, for those installations use 511 Water-Base or 511 H2O Plus) with a paint brush. Any excess sealer that gets on the surface of the stone or tile should be wiped off with a clean, lint free rag before it dries. 
  NOTE: On larger jobs grout can be sealed by retreating the entire area including the tile or stone surface a second time. Be careful not to allow the sealer to puddle or dry on pre- sealed surfaces.

Description

The Rust-Oleum Miracle Sealants 511 Porous Plus MS-04 is a water-based sealer that is easy to apply using a roller, brush, or sprayer. It is clear in color and does not alter the natural appearance of the surface. This sealer is highly effective in repelling water, oil, and other substances that can cause stains and damage. The formula is designed to be breathable, allowing moisture to escape while preventing external substances from penetrating the surface.

One of the significant advantages of this product is its ease of application and maintenance. It dries quickly, typically within 30 minutes to an hour, and can be reapplied as needed without leaving a sticky residue. The 511 Porous Plus MS-04 is also compatible with a variety of cleaning products, making maintenance a breeze.

EXISTING INSTALLATION

SURFACE PREPARATION

• Surface Coating/Wax Removal: To remove existing coatings and/or waxes, use Miracle Sealants Finish Sealer Stripper or appropriate stripper as directed.
• Heavy Duty Cleaning: To remove lime and hard water deposits, efflorescence, rust, grease and other heavy dirt and grime use Miracle Sealants HDAC (Heavy Duty Acidic Cleaner) or Miracle Sealants Phosphoric Acid Cleaner as directed. Use Miracle Heavy-Duty Cleaner (acid substitute) to remove grout haze, built-up grease, dirt and stains from all ceramic, porcelain, grout, glass and natural stone. For a non-acid deep clean use Miracle Sealants Liquid Poultice as directed.
• Light Cleaning: Use Miracle Sealants Tile & Stone Cleaner, Porcelain & Ceramic Tile Cleaner, or Counter Kleen as directed.

EXISTING INSTALLATION APPLICATION 

Follow the new surface application instructions previously mentioned, except now, seal the grout and tile or stone surfaces at the same time. When treating surfaces together, make sure that the recessed grout is saturated.

• CURE TIME: 511 Porous Plus will be dry to the touch in 1-3 hours and may be used for light use then. For optimal results, the area should be kept dry and free from staining materials for 72 hours. Furniture and area rugs can be moved back in carefully after 72 hours.
• CLEANUP: Clean brushes and application tools with mineral spirits, paint thinner or acetone immediately after use.
• HANDLING & STORAGE: Stored at 77°F (25°C), 511 Porous Plus will have a shelf life of 36 months. Store 511 Porous Plus in the original container, properly sealed to avoid contamination and solvent evaporation

Setup Guide

To ensure the best results with the Plus MS-04, follow these steps:

1. Clean the surface thoroughly to remove dirt, grime, and any existing sealants.
2. Allow the surface to dry completely before applying the sealer.
3. Apply the sealer using a roller, brush, or sprayer, ensuring even coverage.
4. Allow the first coat to dry according to the instructions (usually 30 minutes to an hour).
5. Apply additional coats as needed, following the same drying time between coats.
6. After the final coat, allow the surface to dry completely before exposing it to water or traffic.

Troubleshooting

Common problems and solutions when using the Rust-Oleum include:

• Inconsistent Coverage: Ensure the surface is clean and dry before application. Apply thin, even coats.
• Sticky Residue: This can occur if the sealer is not allowed to dry properly. Use a clean cloth to wipe off any excess sealer.
• Yellowing: While this sealer is non-yellowing, improper application or exposure to harsh chemicals can cause discoloration. Follow application instructions carefully and avoid using incompatible cleaning products.

Instructions and warnings include avoiding application in direct sunlight, high humidity, or extreme temperatures. Always read the label and follow safety precautions when using any chemical product.
