Concrete comes in many different types and substrates that can be found both for both interior and exterior applications. There are Concrete Driveways, Vertical Brick Walls, Brick Paver Patios, Basement Floors, etc. Concrete is very porous and can be prone to degradation from Water, Ultra Violet Radiation, wear, and tear, etc. By sealing or waterproofing your concrete surface you will add life and protection to your surface. So what is the Best Concrete Sealer The answer to that is dependent on why you are sealing, what surface you are trying to seal, and what your final expectations are. There are many different types of sealers for concrete and masonry surfaces. Concrete sealers come in both water based and solvent based formulas. They come in generic formulas for all surfaces or formulas that are specific to the surface you are applying to. For example, you would want a Brick Paver Sealer for a Paver Patio and a Chimney Sealant for your Chimney but you could use Masonry. Saver All Purpose Water Repellent for both. So why seal your concrete or brick The main reasons to seal and waterproof your concrete are 1. Preventing hairline cracks due to water expansion during freezethat cycles. John Glad the info was helpful. The coal tar emulsion should be cheaper but would still be my second choice. Rejuvenators can soften some crack fillers, which may. Prevent water penetration and seepage of water through walls and foundations. Enhance the appearance by adding a gloss or darkening the overall color. Prevent damage from deicing salts during winter months. Provide protection from Pitting or Spalling or deterioration of the concrete causing chunks of the concrete to separate from the concrete structure.

Bituminous Surface Treatments Pavement Interactive. A bituminous surface treatment BST, also known as a seal coat or chip seal, is a thin protective wearing surface that is applied to a pavement or base course. BSTs can provide all of the following A waterproof layer to protect the underlying pavement. Increased skid resistance. A filler for existing cracks or raveled surfaces. An anti glare surface during wet weather and an increased reflective surface for night driving. Historically, BSTs have been in use since the 1. BSTs are increasingly in use as a preventative maintenance procedure on flexible pavements of good structure. Purpose. A BST offers preventive maintenance from the effects of sun and water, both of which may deteriorate the pavement structure. BSTs create a new wearing course, as well as a waterproof covering for the existing pavement. A BST makes it more difficult for water to enter the base material, and preventing freeze thaw damage for those locations with below freezing temperatures. BSTs also increase the surface friction of the pavement, due to the addition of the cover aggregate. This combats the effects of raveling, which can make the pavement slippery and stopping difficult. A BST gives good, gripping texture to the pavement surface. BSTs should be applied to a distress free to moderately distressed pavement surface. A two to four year service life is common, while five year service lives are achievable. Materials. BSTs are created using two main materials asphalt and a cover aggregate. Asphalt. Asphalt as asphalt binder, cutback asphalt or asphalt emulsion and aggregate uniformly graded. The asphalt is typically an emulsion. Care must be taken with the weather on the day of construction ideally, a warm day with low humidity is preferred. BSTs should never be constructed on rainy days or when rain is predicted. Rain can dilute the asphalt binder if it has not yet cured, bringing the binder to the top of the cover aggregate after the water evaporates, tires can pick up the loose aggregate or track binder across the surface. Cutback Asphalt. While cutback asphalt is historically an option for BSTs, the solvent used usually gasoline or kerosene is expensive and potentially dangerous. A cutback is asphalt dissolved in a solvent, allowing the asphalt to be pumped and sprayed without heating it to high temperatures. The solvent evaporates into the surrounding air, leaving the asphalt binder. Once the solvent has completely evaporated, the cutback has cured. Fast setting time cutbacks use gasoline, while kerosene is used for longer curing times. Cutback asphalt usage has declined in recent years due to pollution and health concerns. Asphalt Emulsion. Today, asphalt emulsions are more commonly used. An emulsion consists of an oil suspended in water. In this case, the asphalt cement is the oil component. A surfactant also called an emulsifying agent needs to be added in order to make the oil and water mix. Having the asphalt suspended in water allows the placing temperature for a BST to be significantly lower than for a hot mix asphalt. A surfactant offers two benefits one, it causes asphalt to form tiny droplets that will suspend in water by lowering the surface tension between the asphalt and the water. Two, a surfactant determines the electrical charge of the emulsion. Aggregate will have an electrical charge, usually negative. Since opposite charges will attract, it is important to choose an emulsion with the opposite charge, which will enhance the binding of the asphalt to the aggregate. Cationic having a positive charge emulsions are typically used. Figure 1. Close up of asphalt emulsion being sprayed onto a prepared surface. The spray bar allows for consistent coverage of one lane width at a time. Figure 2. The emulsion spray bar in action. Note the distinctive brown color before the emulsion breaks. Figure 3. The emulsion color turns to black after it is said to have broken. Figure 4. The aggregate should be added to the emulsion before the emulsion breaks. Note that in this photo, the aggregate was added too late, which is poor procedure. The next largest by volume ingredient in an asphalt emulsion is the water. Water forms approximately one third of the volume of the emulsion. Asphalt particles will, with the help of the emulsifying agent, suspend in the water. It is important to note that if the emulsion breaks when the asphalt and water separate from one another the emulsion will change from brown to black. The aggregate must be applied and rolled before the emulsion breaks. When the emulsion breaks, the water evaporates, and the asphalt remains on the roadway. The asphalt cement is the primary ingredient in a BST. This asphalt is much like the asphalt used in hot mix paving. Sometimes, a latex or polymer modified asphalt may be used to improve early chip retention or BST durability. Aggregate. Aggregates typically used include natural gravel or crushed stone. These must be clean and dust free, hard, and uniform. This is to provide a durable surface for traffic. It is common to limit the percent of material passing the No. Jukebox Jockey Pro Crack more.

Rolling helps set the stone in the emulsion. Aggregate used in construction of a BST should be placed only one layer thick. The exceptions to this is when adding chokestone or a second BST layer a two layer BST is often referred to as a double shot treatment. Placing too much aggregate will cause aggregate pickup, whereby the well placed stones are dislodged, and may cause automobile windshield damage. A small amount of excess aggregate, more than 5 but less than 1. This will reduce tire scuffing in the freshly laid BST. Aggregate Shape. Aggregate shape can be described as either flat or cubical. It can also be either round or angular. These qualities will effect the seal coat in different ways. If an aggregate is flat, the BST will lose chips excessively in the non wheelpath section of the road bed, or it may bleed in the wheelpath. This is due to the pressure from automobile tires causing the flat chips to settle into the asphalt on their flattest side. The BST then becomes thinner where the tires pass over. Aggregate with a Flakiness Index of 2. Flakiness is not an issue in low volume applications, as many tire passes are needed in one area to cause this phenomenon. However, for most applications, cubical aggregate is preferred due to its stability. Round aggregate is likely to roll and become displaced by traffic. Angular aggregates lock to one another. Areas with frequent snow plowing must take extra care in order to make sure a BST with a round aggregate will embed properly as the snow plow may shave off the taller pieces of stone. On high volume roads, a double chip seal may be the better option. This is when a BST is placed atop another one. The aggregate on the bottom layer should be about twice as large as the one on the top. The smaller stones on top will be less likely to cause windshield damage and the surface is typically smoother than a single seal coat. Aggregate Size. Aggregate gradation and size are important to the success of a BST.
