DESCRIPTION: BOYSEN® Masonry Neutralizer #44 is a liquid acidic substance that is to be mixed with water to neutralize lime activity in new masonry surfaces.
A neutralizer is a substance or material used in the neutralization of acidic water. It is a common designation for alkaline materials such as calcite (calcium carbonate) or magnesia (magnesium oxide) used in the neutralization of acid waters. Neutralizers help prevent: Acidic well water from creating blue-green stains.
Mix one (1) gallon of Island Concrete Neutralizer with sixteen to twenty (16-20) gallons of clean water. Apply the diluted solution with brush, roller or mop over the masonry surface until completely wetted. After overnight standing, brush-off any loose whitish residues that form on the surface.
How to Paint Concrete
Generally speaking, priming is so essential to successful painting outcomes, concrete will always needs a primer. However, the existing surface needs to be primed before painting if: It is unpainted. It is peeling.
Masonry paint (also called elastomeric paint or elastomeric wall coating) is a good choice for concrete painting because it contains binders that contract and expand with the concrete. Exterior house paint can crack and peel on concrete. … No matter how you apply paint, let it dry for a day between coats.
Applying a suitable sealant on top of your masonry paint can offer a range of further benefits. In addition to adding additional protections from damage, it can also prevent the colour from fading due to the effects of the weather. Sealants can offer a great deal of protection to your masonry wall.
Almost any concrete surface that’s in sound condition can be painted. That includes interior floors and walls as well as exterior surfaces such as patios, sidewalks, and pool decks. Just make sure the surface is clean and free of existing coatings or sealers that could prevent the paint from adhering.
Don’t use regular exterior paint — it’s not made for concrete and will tend to crack and peel as the material expands and contracts. Instead, choose dedicated driveway or masonry paint (aka “elastomeric”), which may be tinted to a color you choose.
The masonry paint I manufacture certainly is suitable; it has been applied to patio slab subject to medium traffic (office area).
