External masonry waterproofing with 3-layer plaster system

What do we need?

The outer surfaces of the plaster is absorbent to water, resulting in formation of mold and dirt on the walls. Beyond these, moisture creates many problems in the inner surfaces of the homes.

How do we do it?

The waterproofing of external surfaces of buildings made ​​using the ready water-repellent plaster of THRAKON which prevent the infiltration of rainwater while allowing breathability of the masonry.

For greater protection, we can apply the plaster system, three layers using water-repellent coating on the implementation of the third layer.

Step by step

  • Ensure that the substrate is dry, solid, sound and free from loose particles, dust, paints, waxes and oils.
  • Cut and remove any protrusions of metallic reinforcement in depth 1 cm from the surface and prime. Before the start of the application, wetting the surfaces thoroughly with water. Highly absorbent substrates (e.g. aerated concrete) should be primed with acrylic primer GLX 290.

Plaster surfaces waterproofing

What do we need?

Often plasters fail to protect adequately and over time the walls of buildings from moisture , rain and generally adverse weather conditions. Also due to the expansion and contraction caused by temperature changes during the year and between day and night often plaster cracking resulting moisture entering the building. This moisture freezes during periods of very low temperatures , creating additional cracks

How do we do it?

Adding the plaster polymer latex, THRAKON LATEX 296  improves their properties offering waterproofing , elasticity , resistance to frost and extreme weather conditions and chemical effects of corrosive environments, e.g. near the sea.

Products used

THRAKON LATEX 296

Step by step

  • Reinforcing resin is added to the water of the mixture before mixing with the plaster in a proportion: THRAKON LATEX 296 to water = 1:4 to 1:5.
  • Then to the prepared mixture, add the ingredients of the plaster and stir suitable to create a homogeneous mortar mass with good workability which standing on masonry without falling.

Waterproofing against rising damp

What do we need?

The rising damp due to groundwater or surface waters in soil affect the construction of the foundations through the capillaries of the materials creating major problems such as dissolution and disintegration of construction materials, formation of rashes, cracks and breakages even chemical corrosion and oxidation.

How do we do it?

Perfect protection against the rising damp is  DSF 350 FLEX an elastic, 2-component brushable mortar which create a watertight joint between plate and wall and a peripheral sealing zone between the ground and the wall at a height of 30-40 cm.

Products used

DSF 350

KF  12/7 – F 12/7

Step by step

  • Clean the contact surface of the masonry from foreign materials and lumps and wetted. Then apply two layers  DSF 350 FLEX crosswise in width same as masonry and start building stones with  building mud.
  • After completion of the wall before the plastering, create a sealing zone on the outer walls in height of 30-40 cm from the ground again by applying two layers of DSF 350 FLEX crosswise.
  • Along the connection of masonry with the floor it is recommended to reinforce the waterproofing membrane with elastic fiberglass tape  KF 12/7 or by elastic polyester fabric tape F 12/7, width 12cm.
  • The placement is done in the following way: apply a layer of DSF 350 FLEX, width 15 – 17 cm along the points in need of aid and place the film layer while is still damp. Two more layers follow each after drying the previous one.
  • Next day the masonry can be plastered as normal.

External Masonry Waterproofing with 2-layer plaster system

What do we need?

The outer surfaces of the plaster are absorbent to water, resulting in formation of mold and dirt on the walls. Beyond these, moisture creates many problems in the inner surfaces of the homes.

How do we do it?

The waterproofing of external surfaces of buildings made ​​using the ready water-repellent plaster of THRAKON which prevent the infiltration of rainwater while allowing breathability of the masonry.

In cases of schedule pressure, we can apply the plaster system of two layers using water-repellent coating on the implementation of the second layer.
