- Typical Uses
Chemester® Mortar is an epoxy novolac based vinyl ester mortar designed for use in the pulp and paper industry, as well as the metal working, chemical and food process industries for joining chemical resistant brick and tiles. Applications in the pulp and paper industry include bleach make up tanks, chlorine dioxide towers and preretention tubs, washers and floors.
- Application of The Chemester Mortar
Pointing Mortar : Use standard wall pointing techniques for both new construction, as well as repair of old joints. For new construction with portland cement joints, rake out the joints to a depth of 1/4” (6.4 mm.) minimum and point with Chemester® Mortar. For repointing work, remove deteriorating mortar down to sound substrate or a minimum depth of 1/4” (6.4 mm.) and point with Chemester® Mortar.
Setting Bed : When using Chemester® Mortar as a bed joint over an asphalt membrane, apply a coat of ATLAS® Barrier Sealant Base (without accelerator) over the membrane and allow it to dry. Typical drying times of ATLAS® Barrier Sealant Base are 2-1/2 hours at 65°F (18°C) or 1 hour at 85°F (29°C). Apply the mortar with a 3/16” V-notched trowel held at a 45 degree angle. Place a sufficient amount of mortar to provide a continuous bond coat to the specified thickness. Do not apply more mortar than can be covered in 10 to 15 minutes at 75°F (24°C).
Tile and Brick Joints : Install the mortar using conventional bricklaying techniques. Apply mortar to two sides of the brick forming a “V” profile. Place brick on the setting bed and slide it into place to attain a 1/8” (3.2 mm.) wide joint. Strike excess mortar before the mortar begins to set.
Full Joint Tile Chests and Walls : Install the mortar using conventional techniques. Apply mortar to the sides of the tile or brick forming a “V” profile. Place tile or brick to attain a 1/4” (6.4 mm.) to 3/8” (9.5 mm.) wide joint. Strike excess mortar before the mortar begins to set.
Overhead : Install the mortar using conventional techniques.
Typical Working & Setting Times of The Chemester® Mortar
Temperature Working Time Setting Time 60°F (16°C) 45-55 min. 60-80 min. 70°F (21°C) 25-30 min. 40-45 min. 80°F (27°C) 18-22 min. 25-35 min. 90°F 32°C) 5-10 min. 15-20 min. - Mixing of The Chemester Mortar
The mix ratio of Chemester® Mortar varies depending upon the application:
- A ratio of 100 parts Resin to 350 parts Powder, by weight, is suggested for repointing joints and as a setting bed or full joint mortar for masonry floors and walls.
- A ratio of 100 parts Resin to 400 parts Powder, by weight, is suggested for new construction of tile chest / towers.
- A ratio of 100 parts Resin to 300 parts Powder to 5 parts ATLAS T-ADDITIVE, by weight, is suggested for any overhead pointing, full joint and bed joint installations. The ATLAS T-ADDITIVE enhances the holding characteris-tics without affecting the working time of the mortar.
Stir the contents of the resin container prior to blending. Mix components by hand using a clean, dry, plastic or metal container and a mason’s trowel. For larger batch sizes, a KOL type mixer with a 5-gallon capacity may be used. The mixing speed should be between 60 and 75 RPM. Proportionally increase or decrease resin and powder quantities to attain larger or smaller batch sizes.
Note : The amount of the powder may be varied slightly to obtain the desired consistency. Decreasing the powder component will decrease the estimated unit coverage and will affect the cure times of the mortar. The amount of powder must be within 5%, by weight, of the suggested amount.
Mix Ratio of 100 parts Resin to 350 parts Powder, by weight, is suggested for repointing joints and as a setting bed or full joint mortar for masonry floors and walls.
