Whiteboard Paint Ratios for Small Areas
Many high-quality industrial-grade coatings such as premium ReMARKable Whiteboard Paint are multi-component products in which a chemical reaction that occurs between the components produces a durable and long-lasting coating film. The components come in separate pre-measured containers with the correct amount of each component, and that needs to be mixed at a precise ratio to create the desired result. The chemical natures of the materials in the individual containers are quite different. When blended, they undergo a chemical transformation resulting in a cross-linked polymer (long molecule) substance that develops into a protective coating upon curing.

This is true for ReMARKable whiteboard coatings, which are sold in two separate containers with their components identified by the labels Part A and Part B. When the supplied amount of each part is blended with the other, a usable mixture is produced. The pre-measured containers in each whiteboard coating kit thus allow the product to be mixed and applied without the need to proportion out each component personally. However, even though the two containers are pre-measured forms of packaging, people sometimes mix the coating parts in incorrect ratios. The results are an irregular-looking and unusable whiteboard surface that requires recoating.

Standard Ratio for Mixing Premium Whiteboard Coating

In the case of premium whiteboard coating, the manufacturer’s instructions that come with each coating kit stipulate the proper mixing ratio of Parts A and B, along with clear and detailed guidelines on the correct methods to use for mixing and application. The right ratio for mixing the whiteboard coating parts is 1:2- one part A with two parts B and every kit includes pre-measured containers with the exact amount needed of each component to cover the specified amount of space.

For smaller areas to be coated, the quantities in each container are as follows:

Ratio one: 35-square-foot kit: 4 ounces of Part A and 8 ounces of Part B

Ratio two: 50-square-foot kit: 6 ounces of Part A and 12 ounces of Part B

Ratio three: 100-square-foot kit: 12 ounces of Part and 24 ounces of Part B

Before application, it’s essential to mix only the exact amount of coating that you will need to cover your surface. The containers in the coating kit have the proper amounts of Parts A and B in the right ratio to produce the correct blend for the amount of square footage printed on the kit packaging. However, if you plan to cover an area of a different size than what’s appropriate for the kit you purchased, for example, 30 square feet with a 35-square-foot kit, you should not guess at the quantities you’ll need and instead use containers with precise volume markings to ensure that you’ll end up with a mixture that has the exact ratio of product necessary to cover your area. If you want to simplify things and avoid using separate containers, you can just mix the amount of coating for a 35-square-foot area, cover the surface, and use the remaining amount of coating on another surface as a table, desk, door, or cabinet. Whatever approach you choose, be sure to carefully mix the components for a minimum of three minutes before starting the application process.

Steps to the Proper Mixing of Whiteboard Paint

Step 1 – Parts A and B need to be mixed in a clean container that’s only slightly larger in volume than the quantity of paint you’ll be using. Be sure that the container is entirely free of dirt and debris so that you avoid producing tiny lumps, ridges, or other irregular spots on the coated surface after the coating dries. Also, for a flawless application, the ambient temperature in the room where you mix the coating’s components and apply the mixture should be from 65°F (18o C) to 85°F (29o C). If the temperature is beyond this range, it could have an adverse effect on the proper blending of Parts A and B and on the application of the coating after the parts are mixed. And, as mentioned above, the mixing ratio should be 2:1; that is, mix one (1) part of A with two (2) parts of B.

Step 2 – If you’re planning to apply the white variety of the coating, slowly stir Part B, a water-based whiteboard coating resin, in its container for approximately 30 seconds, then pour and fold Part A, a water-based hardener, into Part B. For the white version of the coating, the procedure of first stirring Part B by itself is crucial because the chemical ingredients in part B need to be homogeneously dispersed all through the liquid prior to mixing it with part A. In this way, you’ll ensure the chemical reaction that occurs between Part A (the hardener) and Part B (the resin) will have the right outcome and produce a functional coating.

Step 3 – After you add Part A to Part B, you’ll need to completely but gently blend the two parts together with the stirring stick provided in the coating kit. Remember that thorough blending of coatings made up of multiple components such as the premium clear and white whiteboard paints is extremely important since the two parts are formulated to react chemically with each other in a precise ratio when mixed. If the parts are not thoroughly blended, this chemical reaction will not occur as designed to, leading to poor performance or possibly even failure of the whiteboard coated surface once it cures. In such a situation, the surface may appear to be adequately cured and show no severe signs of improper blending. However, the finished surface’s look and ability to be easily written on and erased will be diminished because a bad chemical reaction occurred between Parts A and B.

Correct Mixing Ratio of Whiteboard Paint Components is Critical

The right mixing ratio of coating components for a multi-part product such as top-quality whiteboard coating is determined by highly trained and experienced coating formulators and must be adhered to in order to obtain the proper results – an extremely durable and easily erased writing surface. Coating products that cure quickly, such as ReMARKable, are often sensitive to mixing ratio deviations. The performance features of the finished coated surface can be significantly affected by small variations. The appropriate mixing ratio is related to the chemical interactivity of the two reacting components of the coating. With premium whiteboard coating, there are two constituents, each of which has a certain number of chemically active sites that need to chemically bond and thus form the finished whiteboard surface. The reaction is chemically balanced when the two components have an equal number of available molecular sites for the reaction to occur and produce the complex polymer (extremely large molecule) that forms the coating film.

Impact of Off-Ratio Mixing of Whiteboard Paint Components

If Parts A and B of the whiteboard coating formula are mixed at a ratio that differs from the one specified by the manufacturer, then changes in the nature of the finished whiteboard surface can easily occur. These changes are not apparent at times while the coating is being applied and appears only after the coated surface is put into use. In other cases, the imperfections caused by off-ratio mixing become visually evident while the coating is being applied.

Make Sure to Mix the Whiteboard Coating Parts by Hand

Also, to eliminate the possibility of the whiteboard coating’s failure from imprecise or incomplete mixing, you should pay close attention to the tools used and the instructions provided with your coating kit. With many other types of coatings, the parts of multi-component formulas can be mixed with a power mixer or an electric drill with a mixer attachment to make sure that the components are thoroughly blended. However, for top-quality whiteboard coatings, gentle hand mixing with a stir stick is the only technique that should be used. Remember to avoid vigorously stirring or whipping the product to keep from creating bubbles in the coating while mixing by hand.
