2. Substrate

Very important is the identification of all types of support that may be interested to waterproofing. It comes

from a visual inspection of the job site or from the drawing and specifications in the case of new structures.

For the specific sector of the traffic decks, the surface of interest is mainly represented by reinforced concrete.

The asphalt is not a suitable support to these systems with the exception of MasterSeal Traffic System 2259 in

the case for example of footpaths or cycle paths.

The proper and complete identification of the nature of the support is crucial for the success of the intervention

of waterproofing as it forms the basic parameter for the choice of the specific type of primers to be used.

2.1 Identification of the existing joints

For reinforced concrete surfaces the designer/engineer must always recommend, in the case of new works,

or identify, in the case of existing structures, the different types of joints by classifying them according to their

function.

2.2 Treatment of the joints

For the placing of joints, it is always advisable to refer to professional engineering guidelines.

In this critical stage the specialised joints engineer must always carefully assess the maximum movement

envisaged for the expansion joint.

This value is the discriminant factor in choosing the technique for treating this constructional detail.

2.3 Treatment of the floor to wall connections

Immediately prior to application of the membrane, the floor and wall joint areas must be treated with specific

textile tape or butyl rubber tape MasterSeal 944 which will be covered entirely by the membrane. This

procedure is necessary to reduce the specific stresses in the corners and therefore to keep the waterproofing

membrane intact.

2.4 Preparation of the substrate

Prior to the application of the waterproofing system, it is essential to ensure that concrete surfaces are not

cracked, damaged or contaminated with oil, grease or other substances. Remove the loose concrete and then

restored with MasterSeal P 385 Comp D mixed with water only. Prepare the surface by shot-blasting, sanding

or sand-blasting. The precise and detailed evaluation is always subject to a site from a BASF Technical

Service. Always remove dust surfaces with vacuum cleaner.

2.5 Humidity of the substrate

After the phase of the surface preparation of the substrate and before laying the primer, it is necessary to

assess the hHumidity conditions of the support. They should be evaluated with attention the conditions of

service of local underlying coverage. It must be assessed in substance the presence of kitchens, public

places, technical facilities, etc. during summer and winter are thermo-conditioned. In fact these subtle factors

which often do not pay due attention can generate condensation surface interface and thus undermine the

monolithic system with support. In such cases, well-known boundary conditions, it will be necessary to

provide a specific primer barrier MasterSeal P 385. For the particular evaluation is always advisable to have a

visit with our technicians. Only under these conditions, in fact they will be eligible for the primer and then later

the membrane Masterseal M. For cementitious substrates is always necessary to verify the degree of surface

moisture. This operation may be carried out using for example an digital hygrometer or through the empirical

method of the polythene sheet. The value of surface moisture in any case must be less than 4%.



3. Primers

The choice of the right primer to be used for the specific application, starts from the knowledge of the type

of support and any boundary conditions to be assessed always with great attention.

It refers for example:

�� presence or absence of the barrier to rising damp;

�� condensation at the interface;

�� other specific conditions

Once familiar with all the specific conditions you can make the choice of the specific primer.

Below some tables of practical use.

When maximum recoating times have been exceeded, the adhesion promoter MasterSeal P 691 must

be used. Vacuum/wash the surface should it have been open to traffic or put into use even temporarily.

3.1 Application procedure

�� MasterTop P 604: mix both the base and the hardener thoroughly before using. Then blend one pack of

base with one of hardener. In the case of drums, mix base and hardener in the recommended catalyst

ratios. Mix using a low-speed drill (300 rpm) with whisk attachment for approx. 3 minutes until a smooth

uniform mix is obtained. Apply the mix by squeegee or smooth trowel and then pass over the surface

with a short-pile roller to distribute the primer evenly. The tools used for mixing and application of the

material may be cleaned with epoxy thinner E100.

�� MasterTop P 686W: mix both the base and the hardener thoroughly before using. Then blend one

pack of base with one of hardener. In the case of drums, mix base and hardener in the recommended

catalyst ratios. Mix using a low-speed drill (300 rpm) with whisk attachment for approx. 3 minutes until

a smooth uniform mix is obtained. Apply the mix by squeegee or smooth trowel and then pass over the

surface with a short-pile roller to distribute the primer evenly. The primer can be diluted with water if

the surface is in the bituminous sheets, up to a maximum of 25%. After mixing, apply the primer on the

media distributing it with a rubber squeegee or trowel and finishing it with a short hair roller. Apply the

waterproofing membrane Masterseal M when recoating the primer is still sticky and still after 12 hours

(at 20 ° C).

�� MasterSeal P 385: pour component B (hardener) into component A (base) and mix thoroughly. Then add

component C (aggregate) mixing all the time with a mechanical mixer. Continue mixing until a smooth,

lump-free mix is obtained. MasterSeal P385 may be applied with a trowel, as for shallow filling work,

or with a brush, roller or spray diluted with 10-20% water. Always apply two coats with an interval of

16-24 hours between coats. MasterSeal P385 is abrasive and it is therefore advisable to use airless

membrane equipment. Thoroughly clean the working tools with water and detergent immediately after

use. Avoid excessive bends in the hose in order to decrease friction inside it and always position the

spray pump either at operator height or preferably higher. During application of the product make sure

it is constantly agitated. As is usual for waterborne products, do not work in direct sunlight, with wind,

fog or strong hHumidity or when there is a danger of rainfall or freezing. The film formed by this product

requires 7 days at 20°C and 65% rh to terminate the hydration process and become suitable for use in

Primers and properties


3.2 Quartz sand broadcast

To improve adhesion of following layers in the system being used, once the primer has been applied it is

necessary to add, wet on wet, spheroidal quartz having a particle size of 0.3 - 0.8 mm MasterTop F 5, in

the proportion of 0.8-1 kg/m2. The purpose of this procedure is to give the waterproofing system that will

be applied afterwards physical and not just chemical adhesion.

MasterTop F 5 sand quartz broadcast is recommended for MasterTop P604 and MasterTop P 686W.

3.3 Quartz sand broadcast in excess

To give the system the correct skid resistance and abrasion resistance, it is necessary (as provided by

the system) wet on wet, to perform a quartz sand broadcast in excess of spherical quartz with a particle

size from 0.3 to 0.8 mm Mastertop F 5. Look at the table in chapter 1.

the envisaged conditions. It may, however, be coated with epoxy or polyurethane coatings already after

(but not before) 48 hours in conditions of good ventilation (check case by case that the surface moisture

is no more than 4%).

�� MasterSeal P 690 / 691 / 698: bring the material to a temperature of approx. 15 to 25°C. The products

contain pigments, which could settle on the bottom, so as a general rule shake the container well

before use. The best application method is by brush or cloth (by roller and spray for MasterTop P 698).

Spread it all over the surface to form a thin layer, taking care not to apply too much. It is important

when using MasterSeal P 698 to apply it around the details of the joints, between sheets and to

angled areas.

To know more about the application methods and relative technical expedients, always refer to the

product data sheets.



4. Temperature for the application

The temperature of the substrate must be above 5°C for epoxy products and above 8°C for

polyurethanes and in any case at least 3°C above dew point. MasterSeal systems are usually applied

outdoors and sometimes in relatively low temperatures. Prior to applying each layer, it is essential

to make sure that there is no surface condensation or moisture on the substrate. The surfaces must

be dried with compressed air before application, which should be limited to the central hours of the

day. If maximum times for recoating are exceeded, then MasterSeal P 691 must again be used as

adhesion promoter. After application the primer must be protected against direct contact with water

for approximately 24 hours (at 20°C), otherwise efflorescence or a sticky surface could form and would

require remedying.



5. Membrane

5.1 Polyurea sprayed applied membrane

Before application, both components must be pre-heated by means of heating bands at a temperature of

about 25-30 ° C. The substrate temperature should be above 5 ° C and at least 3 ° C above the dew point.

The application of MasterSeal M 689 is performed by means of the specific apparatus hot-spraying

bi-mixer. The market offers different possibilities and for more details contact a Technical BASF CC.

Normally the team consists of two skilled workers and a skilled worker. However, the team can vary by

composition also significantly in function of the complication of the construction details.

Tools used for mixing and applying the material can be cleaned with thinner polyurethane P200. Hardened

material on tools can be removed mechanically.

The component A should be mixed thoroughly before use by means of beater type mixer to ensure

homogenous dispersion of the pigment.

Data for the application of the topcoats

6. Topcoat

�� MasterSeal TC 258 is a single-component polyurethane UV resistant top coat. It is used in MasterSeal

Traffic 2389 to give UV resistance and specific resistance to mechanical abrasion.

�� MasterSeal TC 681 is a two-component finish polyaspartic UV resistant topcoat. It is used in MasterSeal

Traffic 2389 to give UV resistance and specific resistance to mechanical abrasion. It ‘a quick finish (after

7 hours is completely driveway).

Before applying MasterSeal TC 258 mix the product for a few minute to stir at low speed. The substrate

must be free of dust and everything that could compromise adhesion. Apply MasterSeal TC 258 and TC

681 roller taking care to respect the recoating time. Clean tools with thinner polyurethane for P200.

After applying the first coat, wet on wet, spread filler quartz Mastertop F 5 at a rate of 0.8 to 1 kg / m2. This

operation is necessary to give to the system the specific skid resistance.

The second coat of MasterSeal TC 258/681 is required to incorporate the filler quartz Mastertop F 5.

8. Controls

The information in this section could be of help both to the coating contractor and job site management.

8.1 Visual inspection

A first general inspection is made immediately after spraying. If there are areas in which the substrate

texture (surface roughness, aggregates dotted over the surface, etc.) is especially visible, it is necessary

to check immediately if the effective consumption rate is compatible with the envisaged thickness. If the

overall consumption rate is less than expected, another layer must be applied wet on wet over the previous

coat immediately.

8.2 Thinckness estimation

Apart from a thickness estimation based on the actual consumption rate (which is the guideline for the

applicator) there are another two techniques for proceeding with the estimation:

�� the first is non-destructive: for well-defined areas it is sufficient to lay Teflon strips or panels on the

ground which will be covered with membrane during spraying. The precise thickness in real terms can

be measured on these samples produced in real application conditions using a simple calliper or gauge;

the second is destructive: an area for the control is outlined from which the membrane is cut and then

removed so that its thickness can be measured directly. That area must obviously be made good to

guarantee the continuity of the waterproofing.

8.3 Surface hardness estimation

To assess the correct polymerisation reaction of the membrane, a “Shore DUROMETER” which complies

with the main standards in force (e.g. DIN 53505, ISO 7619, ASTM D 2240) is used.

Measurement of the Shore hardness and any deviation from the expected value will highlight any abnormal

situations, so that any maintenance or repair work can be planned.

The advantage of this instrument lies in its ease of use, the frequency of possible measurements and the

utterly marginal cost compared to the usefulness of the collected data.

8.4 Evaluation of the adhesion values

A destructive in-situ control may be carried out using a portable Adhesion Tester of the type

recommended in ASTM D4541 following the procedure laid down in the same standard. This test allows

information to be obtained regarding the modes of breaking (due to tension failure of the substrate,

interface separation, tension failure of the membrane or intermediate situations). A visual inspection

should identify the areas in particular in critical surfaces where it seems highly likely that the application is

defective.


9. Repair technique

10. Reccomendations for safety and storage of materials

If there are areas where defects are found related to Shore hardness, cracks, separation, blistering,

infiltration, etc., it is necessary to proceed with:

�� fully identifying the areas to be repaired; the area needing repair will be the damaged area plus an

adequate adjacent area (approx.. 50 cm beyond the damaged part). The area will therefore be marked

out through an incision which must go through the entire thickness of the membrane and a part of the

concrete;

�� removing the membrane;

�� priming: the primer must be applied on the substrate and the area of membrane that will be overlapped,

which is approx. 50 cm. The specific primer for the type of surface must be used;

�� applying the waterproofing membrane: the membrane will be laid over the whole area treated with the

specific primers.

For any matters concerned with safety and storage of the materials, always refer to the safety data sheet of

each individual product.
