Chlorinated Rubber-Based Floors: What You Need to Know

So you have decided to go for one of the most practical floor paint options for your garage: CRB or Chlorinated Rubber Based Paint or more specifically and more importantly A-Plus Floor Master®
Chlorinated Rubber Based Floor Coating.

Great choice! Read on to learn how to get the most out of your selection—from product specifications, color options, surface preparation, application procedures, and maintenance.

What is CRB Paint?

Chlorinated Rubber-Based Floor Coatings (CRB) are one-component, modified acrylic solvent based coatings designed to deliver superior outdoor durability and extreme abrasion resistance.

They are easy to apply and cure quickly to a semi-gloss finish that withstands abrasion, water, chemicals, and UV exposure. This makes CRB the top choice for exposed areas such as parking spaces, roof decks, and outdoor sports surfaces where constant sun, weather, chemical exposure, and friction occur.

  • Getting Started

Before you begin, here are some things you should know about A-Plus Floor Master® Chlorinated Rubber Based Floor Coating or CRB paints in general:

One-Component, Ready-to-Use

Unlike two-component epoxy paints that require mixing, A-Plus Floor Master® Chlorinated Rubber Based Floor Coating comes in a single 4-liter can. Just mix well before use.

Thinning Instructions

You’ll need a thinning agent to reduce the paint’s viscosity. Use only A-Plus Floor Master® Reducer for optimal results.

    • First Coat (as primer): 25% dilution
    • Succeeding Topcoats: 10% dilution

❓ Do I Need a Primer?

You may use A-Plus Floor Master® Chlorinated Rubber Based Floor Coating as its own primer, just thin your first coat by 25%.
For added strength, especially on steel floors, you can use Glazer Galva-Plus® Epoxy Primer as a base.

How many coats do I need?

At least one coat as primer then as topcoat, one to two more coats.

How long between coats?

Wait one hour for surface dry. But wait at least 2 to 3 hrs. in between coats.

Overnight you can use already for light foot traffic. But give it 3-7 days to achieve full strength before you open for heavy vehicular traffic.

Coverage:

20-25 sqm per gallon/coat for the first coat and 25-30 sqm per gallon / coat for the succeeding coats.

Suitable Surfaces

You can use A-Plus Floor Master® Chlorinated Rubber Based Floor Coating on both concrete and steel surfaces. Just ensure proper preparation by cleaning, sanding, and priming when necessary.

Surface Preparation

For concrete substrates, follow these surface preparation procedures:

    1. Remove any oil and dirt by detergent cleaning.
    2. Sand or use mechanical floor grinder with large grit to level the surface and allow paint to enhance grit and adhesion.
    3. Again, clean the surface and let dry completely before application.
    4. If previously painted, remove old paint with A-Plus SuperTanggal® Paint Remover.
    5. If you can not remove old paint and if it is still new and you know that the old paint has been primed properly, you may simply sand to improve adhesion of the new paint.
    6. If you have large concrete surface imperfection, you need to repair these first to ensure safety, proper adhesion and to make sure your new paint looks good and flawless.

Painting Procedure

For concrete substrates, follow these painting procedures:

    1. Again, ensure all surface to be painted is free from dust, dirt and other foreign contaminants
    2. Your first coat shall serve as your primer/sealer. Apply your first coat of A-Plus Floor Master® Chlorinated Rubber Based Floor Coating at 25% dilution with A-Plus Floor Master® Reducer.
    3. Let cure for at least two hours before proceeding with the topcoat.
    4. Apply 1 to 2 coats of A-Plus Floor Master® Chlorinated Rubber Based Floor Coating at 10% dilution with A-Plus Floor Master® Reducer using either a roller, brush or spray gun.
    5. Allow the surface to cure overnight before subjecting to light foot traffic and 3-7 before subjecting to heavy vehicular traffic.
