KEIM Concretal – Spezialvergütung Dispersion for filler

KEIM Concretal®-Spezialvergütung

Fill Dispersion

1. Product Description

Water-dilutable resin for cement-bonded fillers.

2. Application Field

KEIM Concretal-Feinspachtel is a filling material used by adding with water.

3. Application Instructions

Surface Preparation
Dust, oil and other contaminants on the surface should be cleaned. It is recommended to clean the surface by sandblasting method. It may be necessary to wet the surface slightly beforehand, but the surface should not be fully saturated with water.

Application
Mixing rate is 25 kg of dry KEIM Concretal-Feinspachtel with 4.5 lt water and 1.5 lt KEIM Concretal-Spezialvergütung at 20°C.

KEIM Concretal-Spezialvergütung is first added to water and mixed well. Depending on the temperature conditions, it is recommended that you test before applying the product.

Application Temperature
For application, it is recommended that the air and surface temperature be between 8°C and 30°C.

Consumption

60 ml / m2

Repetition should be applied one more coat at 20°C after at least 5 days.

By adding KEIM Concretal-Spezialvergütung to the KEIM Concretal-Feinspachtel, the adhesion to the surface can be increased. In principle, KEIM Concretal-Spezialvergütung is recommended for filling very thin layers of plaster and defect and small-scale segregated areas. In this case, 1 liter of mixing water is replaced by KEIM Concretal-Spezialvergütung.

25 kg of KEIM Concretal-Feinspachtel,

KEIM Concretal – MKH Corrosion Protection and Bonding Bridge

KEIM Concretal®-MKH

Mineral corrosion protection and bond bridge creating for concrete.

1.Product Description

KEIM Concretal provides protection against mineral corrosion and bonding bridges for the concrete repair system and complies with the guidelines of the ZTV-ING TL / TP BE PCC I-II and DAfStb and European Union regulation 1504-7.

2.Application Field4

Application for Corrosion Protection Purpose

This application against corrosion in order to reinforce rusted steel after sandblasting complies with SA 21/2 and DIN EN 12944-4.

 
Application for the purpose of creating a bond bridge
It is used in civil engineering and bridge construction for PCC I and II applications, to form a creating bridge between cement based surface and KEIM Concretal-Mörtel-R concrete repair mortar. ZTV-ING and DAfStb’s guidelines for building construction.

3.Features of Product

Consisting of a single component, this material is polymer reinforced and acts as a cement mortar and is mixed with water. It provides active protection against corrosion for reinforcing steel and provides protection against chlorine within the scope of concrete repair mortar.

4.Application Instructions

Application Methods
It is applied with a paint brush to protect against corrosion and to form a bond bridge.

Surface Preparation
Reinforcing Steel
For reinforcing steel, the surface must be prepared to a standard degree of cleaning in accordance with DIN EN ISO 12944-4. There should be no rust layer on it and should be free of other contaminants. The sand ramp with quartz-free sand is a suitable cleaning method.

Concrete Surface
The surface must be clean, solid, open-pored and absorbent. Concrete surfaces must be at least B25 quality. Concrete sand, dust and dirt are removed by sandblasting. Surfaces applied according to the joint sealant and the protection against evaporation are not suitable (sections 3 and 4 of ZTVING and See table 3.4.2). For example; The surface must be suitably prepared before treatment using a suitable method such as sand blasting or high pressure water spraying.

Mixing Process
KEIM Concretal-MKH sürekli karıştırmak suretiyle belirli bir miktar suyun içine eklenir ve ürün istenilen kıvama gelene kadar karıştırma işlemine devam edilir. Ardından homojen bir karışım elde edilmiş olur. Karıştırma süresi 5 dakikadır. Düşük devirde çalışan karıştırıcılar kullanılmalıdır.

Mixin Ratio
Approximately 3.6-3.8 liters of water is required for a 20 kg package and approximately 0.9-0.95 liters of water is required for a 5 kg package. Water is added to the desired consistency and depending on the temperature conditions.
(Low temperature = Low water requirement; High temperature = Excess water requirement)

Corrosion Protection Purpose
Application
KEIM Concretal-MKH is applied in two or three layers to the steel surface prepared by using suitable paint brushes. Two applications for PCC applications and three applications for SPCC applications are required. Each coat should be applied homogeneously and cover the entire surface. In order to obtain the required application rate, all sides should be covered.

Wating time at 20°C: 1st floor immediately after dusting. Second floor after at least 3 hours.

It should be applied after at least 3 hours for bond bridge application.

(At least 3 hours after the 3rd floor for SPCC, SPCC should be applied once after 12 hours).

Application for Creating Bond Bridge

The cleaned surface must be pre-wetted and, if possible, kept moist for 24 hours. If not possible, KEIM Concretal-MSC should be kept soaked for at least 2 hours before application. Brush the KEIM Concretal-MKH firmly with the previously prepared area and apply bond bridge over the entire area. During the working period, apply KEIM Concretal-MDG prepared in the form of a mixture (see table “Technical Data bu for this). Hardened KEIM Concretal-MKH should not be diluted with water nor mixed with the new KEIM Concretal-MKH. Immediately apply KEIM Concretal-Mörtel-R to the wet surface without allowing KEIM Concretal-MKH to dry, otherwise pre-coat the surface with KEIM Concretal-MKH. Work with KEIM Concretal- MKH part by part in large areas.

Immediately clean materials, machines and mixers with water after use. Once hardened, it can only be removed mechanically.
