Acid Stain Sealers
Protect your beautiful new floor
Selection of a proper sealer for your acid stain project is an important step to keep your artwork looking new. There are many different sealers available so it can be quite confusing sometimes. The reason there are many types of sealers is they all have pros and cons. There is not a perfect sealer on the market yet that meets the requirements of every situation.
First we will talk about options for an outdoor application. Sealers applied outdoors have to meet an extra set of requirements- which is resistance to UV, salt, elements, freeze thaw cycles, and allow vapors to escape from underneath. Acrylic sealers are the most common. They are usually solvent base products for outdoor use. Most waterbase acrylics are not as durable and recoating a textured surface is difficult. Acrylics yield a good coverage per gallon at a fairly low cost. Most solvent based acrylics have good adhesion, let the concrete breath, decent UV resistance and are easily recoatable. They can be slippery when wet but Trugrip can be added to the sealer as an anti-slip agent. Usually a high gloss product will be used to improve color visibility and depth.
Silicones are great for outdoor use. Old technology wasn't suitable for floor applications - the silicone did not have abrasion resistance or enhancing properties. Now there is Heal and Seal Deco, this is a 100% silicone product that has incredible UV resistance and weathering properties. Heal and Seal Deco chemically binds to concrete, unlike most sealers that only have mechanical binding. Heal and Seal Deco also darkens and enhances the concrete with a highgloss in a waterbase form.
This product rivals any outdoor sealer in ease of application and durability.
Acrylic- Urethanes are great for outdoor use. They provide excellent gloss, abrasion resistance, and stability. This product is a little more pricey than standard acrylics but will outlast it at least two fold. Acrylic urethanes are a two component system so you have to accurately measure/ mix, and then you have a limited pot life in which the sealer must be used or discarded.
One more choice remains for outdoor applications and that is a siliconized acrylic. These sealers produce a satin finish. Some of the characteristics of a waterbase siliconized acrylic are great adhesion, water repellency, and uv resistance. Water base siliconized acrylic sealers are also environmentally friendly and recoatable. One aspect to consider is the abrasion resistance is slightly lower than solvent base acrylic. Protect is the product available that meets these requirements.
Almost any coating can be used indoors for sealing acid stain because it is not exposed to harsh weather conditions. Keep in mind though, high solvent sealers can produce noxious flammable fumes. Waterbase products or high solids sealers are a better choice where ventilation is limited. Waterbase acrylic is fairly inexpensive and easy to apply, but not extremely durable.To combat the durability issue we recommend a couple coats of floorshine to act as a sacrificial wear surface. Floor Shine is an acrylic modified wax that will have to be reapplied every one to two years depending on traffic. Floor Shine is also fairly inexpensive, goes a long way and is eay to apply.
Ultrathane 1000 is the recommended product for interior applications. This sealer is a single component urethane. It is easy to apply, easy to clean up, has great abrasion resistance, less than 100 VOC, No foul odors or fumes, doesn't yellow from UV exposure. Ultrathane 1000 color enhances and leaves a gloss to high gloss finish. Whether you are DIY or a contractor this is a good choice. Ultrathane can be spray applied and backrolled or simply rolled or microfiber applied. You would not use this if you are after a thick coating that substantially darkens the substrate (ie epoxy or polyaspartic).
Protect is a waterbase siliconized acrylic that will provide an average wear surface,great adhesion, and stain/ water protection than standard waterbase acrylic. Floor Shine is also compatible with this product as an additional protectant.
Urethane acrylics will yield a high gloss, durable finish. It is a two component system with a mid-level cost, and mid-level application difficulty. It is also recommended for garage floors.
Waterbase epoxies are a good choice for indoor applications. They are two component systems that usually have a bond coat and finish coat. They will generally provide a semi gloss finish. They are easy to apply have a long pot life and are more durable than waterbase acrylics. Epoxies are subject to some yellowing with enough sunlight exposure.
100% solids epoxy systems generally achieve a high gloss that is very durable. Keep in mind any sealer can be scratched which results in cloudiness or dulls the finish/ clarity. A high build or thick coating is possible with epoxies which a dimension of depth to the project. The cost is on the more expensive side and application requires more skill. Epoxies are two component systems with a limited pot life. This is a thick material that can't be simply rolled or sprayed on. Typically a squeege and porcupine roller is used for application so we recommend you have some experience before attempting a large floor. Garages take extra abuse, not only from vehicles, but tools, salt, chemicals, etc. 100% solids epoxy will work great for garage applications. epoxies are subject to yellowing with enough sunlight exposure.
Polyaspartics are a type of polyurea coating that is also a two component system. They are known for high gloss, abrasion resistance, and high cost. This sealer is probably the most difficult to apply if you are not familiar with it, but yields exceptional results. Pot life is the shortest of all the systems.
Polyurethanes are a usually two component systems, although there are some decent one component available. They have high abrasion resistance and achieve a gloss to possibly high gloss finish.They achieve good adhesion and are mid level difficulty for application. The drawback is, almost all will yellow even with sunlight through a window. Until now there is Ultrathane 1000 - see above or click the link below.
