Krystol T1 and T2 is a surface-applied crystalline waterproong treatment for concrete structures
that is used to protect against the ingress of water. It is a dry powder, that when mixed with
water becomes a coating that is applied to the inner or outer sides of a concrete structure. Use
these instructions in conjunction with the Krystol
®
Crack Repair System (Application Instruction
5.11 – Waterproong Cracks, Holes and Joints.) to create fully tanked, waterproof concrete
structures. For spray application, see the additional information in Application Instruction 2.12 –
Waterproong with Surface Application (Spray Method).

The Krystol T1 and T2 Waterproong System is an effective waterproong system for rigid
concrete structures only and may not be reliable for structures that experience constant or repeated movement. Consult a
Kryton representative for project specic recommendations. Air and surface temperature at the time of application must be at
least 4
o
C (40
o
F).

Read the Material Safety Data Sheets (MSDS) for these products. For professional use only. These products become extremely
caustic when mixed with water or perspiration. Avoid contact with skin or eyes. Avoid breathing dust. Wear long sleeves, safety
goggles and impervious gloves.

1. Repair all defects, including cracks and honeycombs, before applying Krystol T1 and T2 using the following procedures:
a. Cracks and joints: Application Instruction 5.11 — Waterproong Cracks, Holes & Joints
b. Tie holes, honeycombs and general defects: Application Instruction 5.31 — Waterproong Tie Holes and
Defective Concrete.
c. Pipe penetrations: Application Instruction 5.33 — Waterproong Pipe Penetrations (Existing Construction).
: All leaking defects must be repaired. However, even defects not currently leaking may leak in the future if not
repaired before applying the surface coating. In most cases, all defects should be repaired whether they are currently leaking
or not. Consult your Kryton representative for project specic recommendations.
2. Concrete surfaces must be clean and free of paint, sealers, form release agents, dirt, laitance or any other
contaminates. Prepare the surface by sandblasting, high pressure water blasting (minimum 3,000 psi), scarifying, shot
blasting or other method of mechanical surface preparation to remove loose concrete and surface contaminates.
Concrete with some exposed aggregate is ideal. Wash and rinse the surface with a detergent or concrete degreaser
if needed.
3. Even for uncontaminated surfaces, mechanical surface preparation will assist by opening up pores closed due
to smooth trowelled surfaces, formwork etc. The freshly roughened surface will provide maximum adhesion and better
penetration of the waterproong chemicals.
: Acid etching is not recommended. If acid etching must be used, all traces of acid must neutralized and rinsed away
before applying the Krystol T1 and T2.
4. Surfaces to receive Krystol T1 and T2 must be brought to a saturated-surface-dry (SSD) condition. The concrete must
be completely saturated with water to allow the Krystol chemicals to penetrate deeply and react. The outer surface,
however, must be only slightly damp, so as not to dilute and weaken the bond. Thoroughly pre-soak the surface with
water; then remove excess water with a sponge or vacuum just before applying Krystol T1.
: High pressure water blasting is effective at cleaning and saturating the concrete in one step.
