White & Colored Pool Interior Finish Agreement

 

. This agreement applies to the pool plastered at (address):

The contractor agrees to apply the pool interior finish at the above address and guarantees that for a period of one (1) year the interior finish will be watertight. Cementitious surface coatings are actually semi-permeable membranes. They allow small amounts of moisture to permeate through and into the substrate, over time. The finish will not de-bond or delaminate provided that the pool remains filled with water, structurally sound, and that the start-up procedures recommended by the National Plasterers Council (NPC) are followed, and providing that all water chemistry after start-up is properly maintained in accordance with the Association of Pool & Spa Professionals (APSP) published standards recommended practice of maintaining the Langelier Saturation Index at 0 to +/- 0.3. Water chemistry consists of: chlorine levels, total alkalinity, pH, hardness (calcium & magnesium), stabilizer levels, iron, copper and total dissolved solids (TDS).

Pool Interior Finishes are composed of materials which may have inherent shading and/or color variation which is normal and should not be construed as a defect. Due to environmental factors such as humidity, temperature, etc., during the installation process, normal color variation within a surface coating, also called normal mottling, which is generally uniform shading, blotchy or cloudy appearance across the surface of a cementitious surface coating may appear. These variations may be more pronounced on a cloudy day or at night with the light on. These conditions are beyond the contractor’s control. Discoloration or mottled-shade variation is not considered a failure or defect, but is a characteristic of most cementitious products, not needing remedy. It is a normal occurrence of most exposed aggregate finishes to have variation in the surface aggregate density, or variations in the concentration of aggregates across the finished surface.

The Homeowner agrees that pool interior finish is NOT guaranteed for evenness of color and may not be the exact shade anticipated. The shade and color may vary and “fade” over time. Homeowner understands that crazing (check cracks and hairline cracks) may be noticeable and may be quite pronounced with colored finishes.

Homeowner has read and acknowledges the above conditions

Note: We urge you to contact your NPC professional applicator for more information specific to your pool or spa. Chemical treatment alone will not produce sanitary pool water. A filtration system in proper operation along with a regiment of care including pool brushing will produce the optimal results for a clean and safe pool.
