Dampseal

Technical Data Sheet

1.  DESCRIPTION

Antel Dampseal is a low viscosity, single pack, moisture curing Polyisocyanate prepolymer which is  Amber/Clear in colour.

2. USES

Dampseal is used to seal walls and floors against rising damp.  As a binder for friable concrete and as a waterproof membrane before floor screed application.

3.   PACKAGING  

1 litre, 2.5 litre and 5 litre non returnable containers.

4.   COVERAGE

The coverage rate is dependent on the porosity of the masonry and to a great extent on the surface profile.

Coverage on masonry of average porosity is in the range of 25 - 30 mē per 5 litres.

5.   STORAGE

FLAMMABLE LIQUID.

Store in cool, dry conditions in original containers.  Protect from freezing.  Keep out of reach of children.

The store should be clearly marked.

6.   HEALTH & SAFETY   

6.1 Use in well ventilated areas.  Avoid contact with eyes and skin.  Wear suitable protective clothing. Eye protection is strongly advisable.

6.2 If the material comes into contact with the eyes, irrigate immediately with copious amounts of water and medical attention should be obtained.

6.3 Wash any spillages with cleaning solvent and wash the cleaned area with soap and water.   The material may cause skin irritation.   Avoid inhaling fumes.  If affected remove to fresh air.

DO NOT SMOKE - AVOID NAKED FLAMES - HARMFUL IF TAKEN INTERNALLY.

7.   SURFACE PREPARATION

IMPORTANT.

All surfaces must be clean and free from all forms of contamination.  Floors should be swept, vacuumed or scraped clean to remove all traces of dust, laitance or plaster.  The final bond of Dampseal will only be as good as any coating left on the floor.  It is most important that areas are well prepared.  The areas to which Dampseal is to be applied will be better dealt with when they are as dry as possible.  Wet areas will restrict the degree of penetration and may lead to delamination of the Dampseal.

8.   APPLICATION

Pour the Dampseal into a suitable container and use at once.  Mixing is not required.  Do not return any unused Dampseal to the original container as this may cause the entire contents to gel.

Dampseal may be applied by brush or roller.  Care must be taken when using a roller so that air is not entrained in the liquid.  Avoid overworking the Dampseal so that air bubbles do not form in the finishing coat.  Three coats are normally required for full protection but it may be necessary to use a further coat on very porous surfaces.  Second, third and fourth coats must be applied as soon as the previous coat is touch dry.

No longer than four hours must elapse between coats.

9.   CLEANING EQUIPMENT.

Tools and equipment should be cleaned a soon as the work is completed and it is advisable to clean tools at each interval of work.  Cleaning is best carried out using Antel Glaze Coat Cleaning Solvent.  The cleaning must be thorough and it is not acceptable to simply stand tools in the cleaning solvent.
