[To construct waterproofing agents on top of existing urethane]

 
[Basic use material]

​
▶ TanTan One Tan Waterproofing Agent (ST-01)
▶ Brush, Roller

[Construction Method]

1. Construction steps : ① The top of the railing → ② wall → ③ floor

​
2. Preparations before construction

​
   1) Clean surface (oil, moisture, foreign substance)

​
   2) Where the urethane is inflate or lifted.
        ① Cut out the inflate area with a knife, remove the lifted, and dry the floor completely. (It’s inflate because there is moisture inside)

        ② If the lifted urethane is thick and there is height difference after work ①

             A) Mix TanTan OneTan Waterproofing agent : Water in 1 : 1 ratio and dry it after applying it once. 

                 (Drying hours : 30 minute ~ 1 hour / 25°C, under 60% humidity)

             B) Mix TanTan One Tan waterproofing agent(1) : Water(2) : Remitar(7) ratio or 

                   TanTan One Tan waterproofing agent(1) : Water(1) : Wet sand(8) : Cement(2) ratio. 

                   Fill it up to the height differences and dry it completely. It’s very important to dry completely when plaster. 

                   (Drying time : more than 72hours, 5mm thickness - 25°C, under 60% humidity)

                   (If the plaster thickness is more than 5mm, the drying time will take longer.)

   3) Where the urethane cracked
       ① Cut along the surface crack with a knife to expose the crack in the inner floor and then injected TanTan Crack Waterproofing Bond[C-5]

       ② Use a TanTan Crack Waterproofing Bond (C-5) to inject cracks on the surface repeatedly until the cracks are filled.

       ③ Wall cracks
           A) Fill up with TanTan Waterproofing Cream (C-75)

           B) Using a TanTan One Tan Waterproofing Agent and Reinforcing fabric, construct and dry it in the order of

                 “Apply waterproofing agent, spread reinforcing fabric, and apply waterproofing agent.” 

   4) Be careful when you walk on the floor that applied waterproofing agent during construction because the background may be 

       separated if the waterproofing agent is on the bottom of the shoes.

       (You can wear clean shoes, wrap shoes with reinforcement fabric or work with additional shoes or socks.)

​

​3. Waterproofing agent apply

   1) Top of railing, corner construction
       ① Apply a undiluted solution of waterproofing agent to the surface, spread out reinforcing fabric and apply waterproof agent. 

    2) Rail wall construction

       ① Mix TanTan One Tan waterproofing agent(2) : water(1) ratio, apply a waterproof agent on the wall, spread out  the reinforcing fabric and apply again. 

             (When mix with water, stir well for 5 minutes)

   3) Floor construction
       ① Spread out a line of reinforcing fabric on the floor.
           A) Start from the inside on the other side of the doorway.
           B) It's convenient to apply a line of waterproof agent at the beginning of the floor, attach the reinforcement and spread out.

      ② Mix TanTan One Tan waterproofing agent(2) : water(1) ratio, apply it on the reinforcing fabric. 

           (When mix with water, stir well for 5 minutes.)

              A) Apply the middle part first so that the waterproof agent is fully permeated into the reinforcing fabric and is attached to the surface 

                   without bubbles, and push it slowly on both sides. 

                   (A weak attachment or air bubbles can cause lifting or swelling and increase the consumption of waterproofing agent.)

     ③ When spread out 2nd reinforcing fabric, overlap 5cm on previous reinforcing fabric.
     ④ Apply a mixture waterproofing agent of ② on the reinforcing fabric.

     ⑤ Construct sequentially in the same way.
     ⑥ Dry completely after reinforcing fabric construction. (Drying time : 5~6 hours, temperature of 25°C, humidity below 60%)

    4) Mix 10% of water or use undiluted solution of TanTan OneTan Waterproofing Agent[ST-01] and apply more than 2times. 

           (1st apply, re-apply after drying) Complete after curing (5hours).

​

​

[Caution for construct floor]

​
    1) Work and cure at above 5°C. ( It is difficult to form a waterproof layer if it goes sub-zero temperature before drying)

    2) After applying the waterproofing agent, consider the drying time. (If it’s sub-zero temperature , it freezes and cannot be used.)

    3) Refer to the weather forecast as it may be washed out if it rains before drying after work.

​

[Storage method]

​
Considering the area to be applied, pour the amount to be used in a separate bowl and store it at cool room temperature. 

By covering the original product well to prevent foreign substances from entering. 

Store it so that it does not freeze in winter. (If you hammer the lid, it will be re-sealed.)
