Remove Paint Without Harming Masonry
A New York City contractor was struggling to remove several layers of elastomeric coating ….
Paint on masonry is a bad thing—whether used for aesthetic reasons, to cover up stains, or as an attempt to bridge cracks and prevent water infiltration into porous stone or brick.
Due to the lack of vapor permeability, latex, acrylic, and elastomeric coatings accelerate delamination. Removing these coatings is the only way to allow the masonry to breathe and to let water and vapor escape.
Careful consideration is needed before attempting to remove latex, acrylic, or elastomeric coatings. The wrong process or product will cause further damage—for example, high PSI pressure washing and highly acidic removers will damage the substrate.
Competitive products required multiple applications to be effective. This was not ideal for the contractor.
The contractor reached out to the local Cathedral Stone Products technical representative for on-site assistance.
Cathedral Stone Products manufactures two paint removers that are safe and effective when applied properly: Light Duty Paint Remover and Heavy-Duty Paint Remover. These products are specifically engineered to remove coatings from masonry structures. They are even suitable for delicate historic stone surfaces such as limestone, sandstone, and tuckahoe marble. Because our paint removers contain no acid (or contain very little, in the case of our Heavy Duty Paint Remover, which has as much acid as is found in a lemon) there’s no need to worry about damaging the substrate.
Mock-ups of both Light and Heavy Duty Paint Removers were extremely effective.
Both types of pain removers are simple to use. Just apply to the surface, let dwell for 18 hours, and then remove with water from a garden hose. These removers are so effective they will often remove more than one layer of coating in a single application, thus saving the contractor time, material, and labor costs.
And using products that are not highly acidic or solvent-based is also beneficial to workers and the public in general. No plastic cover is necessary. No separate neutralizer is required. No chemical PPE suits. Just a simple rinse with water and clean-up.
Like all products in the CSP System of cleaners, strippers, and removers, these products are safe for masonry, safe for the environment, and safe for the people who use them.
