10-99VO Vertical and Overhead Patch
10-99VO Vertical and Overhead Patch- Great for Pool Walls
Acrylic polymer modified repair compound for vertical and overhead work.
Description
10-99VO is supplied in a pre-packaged unit containing an acrylic polymer liquid and a low density powder mix. This unique combination makes 10-99VO highly suitable for vertical and overhead concrete and masonry patching and repair. 10-99VO has better adhesion, is more waterproof and freeze thaw resistant then standard mortars or stucco. 10-99VO will repair concrete block , brick and masonry.
Surface Preparation:
Concrete substrate should be structurally sound. Any loose or unsound concrete should be hammered out. Surfaces must be entirely free of oil, grease, paint, corrosion deposits, dust, laitance, or other surface contaminants. Any embedded steel should be cleaned the exposed metal should be coated with Permabond E-300 primer prior to the application of the vertical and overhead patch slurry coat.
Mixing:
10-99VO is supplied in pre-packaged units. Mix one bag of 10-99VO powder to 1 gal. of 10-99VO liquid. (Always add the powder to the liquid.) A slow speed drill and mixing blade is preferable to hand mixing.
Priming:
All surfaces should be primed with a slurry using a stiff mason’s brush. The slurry consists of 2 parts by volume of powder mixed into 1 part volume of liquid. When substrate temperatures are in excess of 90 degrees F or where the substrate is highly absorbent dampen the area prior to application of the slurry.
Application: While the slurry is still damp apply 10-99VO by trowel. The maximum thickness of any one layer of 10-99VO will depend on its consistency, location and the profile of the substance to which it is applied. Typically a vertical layer in excess of 3 inches is easily achieved, while overhead applications may only sustain 1 ½ to 2 inches in any one unsupported application. For deep overhead repairs it is good practice to provide mechanical anchors, studs, etc. Small quantities of 10-99VO liquid may be added or held back to enhance trowelling consistency
