HYPERSEAL® Application Guide

This method of application guide outlines the general requirements for the successful application of HYPERSEAL® products regarding joint
sealants installation and ensuring maximum performance.

JOINT DIMENSIONS
To make sure a sealing joint fulfils its requirements under all conditions it has to maintain a dimension ratio of 2:1 with a maximum joint depth of 3cm.
SURFACE PREPARATION
Non-porous substrates such as metals, coated surfaces or plastics should be cleaned from any dust or dirt as well as for any oils or greases to be removed using an appropriate cleaner. For porous surfaces such as concrete, cement, cement boards etc. remove all loose particles such as dirt or laitance. In the event that the substrate is contaminated with oils or other contaminants, power wash cleaning or abrasion cleaning needs to be performed. Surface should be dry prior to sealant application.

INSTALLATION OF BACKING ROD
It is recommended to use closed-cell polyethylene backing rods for joint sealing. Make sure that the backing rod’s skin is not damaged during the installation as this may influence the joint’s quality. Check the position of the backing rod to maintain a 2:1 ratio on joint dimensions.

APPLICATION OF PRIMER-T ON NON-POROUS SUBSTRATES
Apply masking tape to the surfaces next to the joint to keep excess primer from reaching other areas. Apply PRIMER-T with a clean lint free
cloth or paper towel onto the surface. Let it cure for least 10-15 minutes.

APPLICATION OF MICROPRIMER-PU ON POROUS SUBSTRATES
Apply masking tape to the surfaces next to the joint to keep excess primer from reaching other areas. Apply MIRCOPRIMER-PU with a clean
brush at a consumption of 100-200gr/m2.

APPLICATION OF HYPERSEAL ® SEALANTS

Masking tape can be used to keep excess sealant from contacting adjacent areas and offer better aesthetic results. Apply the sealant using a caulking gun and make sure that the sealant is in full contact with the joint sides. Avoid air entrapment by keeping the tip of the nozzle on bottom of the joint. Use a spatula to remove excess material and tool the sealant accordingly. Complete tooling and remove the masking tape.
