- Handling Characteristics
Blome Sealant 63 is available as a two component, fast curing material. It is installed using dual cartridge caulking tubes or with a plural component pump. Mixed Sealant 63 begins the curing process immediately upon mixing. The material exhibits rapid cure, with an initial set of 60 minutes, making it ideal for quick turnaround applications.
- Application Guidelines
Ideally the floor surface and joint should be kept dry prior to installation of Sealant 63. However, if joint surfaces are damp, not wet, or could become damp, joint edges can be primed using an appropriate Blome Primer.
- Floor Joint Design
For maximum sealant performance, the following design principles should be followed. A closed cell backer rod should be inserted into the joint, after surface preparation, at a depth equal to ½ of the joint width. Minimum joint width and depth of sealant should be no less than ¼”. In food service applications or severe chemical environments, a full depth sealant joint is recommended.
- Surface Preparation
All surfaces must be clean and dry, void of oil, grease, rust, dirt, dust or other contaminants that may inhibit proper adhesion. For porous surfaces such as concrete, wire brushing is recommended, followed by vacuuming to remove all residual dust, and for non-porous surfaces such as steel, solvent wiping may beadequate.
- Masking & Protection
Since installation of Blome Sealant 63 should follow completion of the floor surface, it is advisable to mask the surfaces adjacent to the joint to minimize cleanup of the finished floor surface. Avoid foot traffic for 30 minutes and 1-4 hours for heavy vehicle traffic and chemical exposure.
- Application Equipment
Blome Sealant 63 is installed using either dual cartridge caulking gun with static mixer tip or using plural component pump with caulking tip. Dual cartridge caulking guns are available from Blome International, static mixer tips are supplied with each dual cartridge kit. Contact Blome International for specifications on plural component pump and related equipment
- Mixing & Application
Mixing of Blome Sealant 63 takes place in the static mixer tip or plural component pump. For best results, install sealant with a continuous motion, trying not to stop during the length of the joint. This can result in unmixed sealant in sections of the joint. Fill joints from the bottom up to prevent voids within the sealant. Excess sealant is cut off to floor level.
- Touch-Up & Recoating
Short filled joint sealant or air pockets are best repaired by full removal of the sealant in the affected area and re-installation of the sealant.
- Clean Up
Hand tools and equipment may be cleaned with xylene or MEK after use. Cured material may be difficult to remove.
