• Suitable for Filling joints in Floor screed or Terrace screed or crack filing in vertical or over head application.

Joint Preparation
The substrate for the application of Mycoflex 4000GV should be
free from any unsound substances, oil, dust, grease, vegetations
etc. All the old sealants if any should be removed completely.
Cleaning should be done by any mechanical mean to achieve a
sound surface. If the surface is porous then it should be brushed
with mechanical brush so that all the impurity will be removed for
better adhesion.

The joint width should be kept uniform through out the section.
Before application of the Mycoflex 4000GV the joint the residual
moisture should be less than 4%. The Permitted total deformation
and the prospective mechanical loading must be considered by
constructive laying of the joint width.

Joint Filler

For Joint Filling Backer Rod can be recommended as per joint
width and depth. While filling the Backer rod into the joint chare
should be taken that the backer rod should be packed tightly in the
joint so that it can provide suitable non–movement able cushion for
the sealant throughout the joint. During choosing of the bond
backer care should be taken so that it will not bond with the
sealant. If there is any chance that the backer rod can be bonded
with Mycoflex 4000GV then in that condition Bond breaker can be
recommended before application of sealant. For better result
Closed–Cell Polyethene based Mycoflex Jointfiller PE can be
recommended. The joint depth must be limited to approx. 50% of
the width, however it must be at least 10 mm as per DIN 18540.

Priming

Before the application of Mycoflex 4000GV priming the surface
with Mycoprime 4000PS because it provides better adhesion.
The primer must penetrate the joint–sides completely and over the
entire area.

During application primer care should be taken that it should not be
exposed more than 4 hrs depending on ambient and surface
temperature. The interval between priming and application of
Mycoflex 4000GV should be at least 1hour and no more than 10 hrs
at 200 C

Mixing

The base and the hardener component must be mixed together
thoroughly and homogeneously. Only mechanical mixing with an
electric hand drill (200–400 rpm) and an attached special mixture is
permitted. To prevent mixing mistakes, we recommended to mix 3
minutes. After re–potting mix another minute.

Application

Mycoflex 4000GV can be applied by using air guns with rebound–
nozzles at 3 bar to 4 bar or from pressure pots. Or by manually. Then
after application of Mycoflex 4000GV the sealant can be leveled or
smoothen by help of sealant leveling tool. During application of
sealant it should be bubble free. Its pot life is 60min at 230 C and
50% RH. High temperature and high humidity can shorten the pot life
of the material. Material which is cured or partially cured must not be
used for joint filling.

Safety Advice

When applying the primer Mycoprime 4000PS, as well as Mycoflex
4000GV, please take note of safety information and advice given on
the Packaging labels

For any specific critical application and further technical
Specification, please take help of Technical team of MC–Bauchemie
