Painters Caulk

Technical Data Sheet

1.  DESCRIPTION

Antel Painters Caulk is an easy to apply waterborne permanent flexible acrylic emulsion sealant which provides and efficient seal between materials where slight movement is likely to occur.  It is based on a durable pure acrylic emulsion processed with a high level of both wet and dry state fungicides making it suitable for both internal and external decorative sealing.  External use is permissible provided that the weather conditions are likely to allow the development of a substantial skin before exposure to rain.   It can be over coated with both alkyd resin and water based paints.

2.  USES

Typical interior uses :-

• Sealing gaps around window and door frames.
• Sealing up to skirting boards and covings.
• Gives flexible seals to cracks in plaster.

It can be over coated with wall coverings as well as over painted, making it a versatile decorating aid.

Typical exterior uses :-

• Sealing low to medium movement construction joints between brick, concrete, timber etc.
• Sealing joints in timber frame constructions
• sealant for perimeter pointing around doors and windows.

It can be applied to surfaces which are damp and will remain flexible long after traditional oil based mastics have failed.

6.  HEALTH & SAFETY

Wash any material spillage from the skin while still wet.  Do not use thinners, solvents or white spirit to remove. If in contact with the eyes wash copiously with clean fresh water.  If irritation persists seek medical attention.  Avoid repeated or prolonged skin contact.  Ingestion - Rinse mouth and throat with water immediately.  DO NOT INDUCE VOMITING.  If inhaled may cause nausea.  Remove to fresh air and seek medical advice.  Ensure adequate ventilation during application.

Keep out of reach of children.

7.  APPLICATION

All surfaces should be dry, clean and free from grease before application.  Wood, plaster and brick may be damp but not running wet.  Use mechanical abrasion to clean porous surfaces before application.

For extra performance in movement situations a primer can be prepared by diluting one part Antel Painters Caulk with two parts water, and mixing thoroughly.  The primer should then be brush applied and allowed to dry for two to three hours before applying the Painters Caulk.  Alternatively Antel PVA Bonding Agent may be used on the surface.

For internal cracks in plaster the shoulders of the crack should be widened to a minimum of 3 - 4mm to ensure adequate penetration and performance.  For internal sealing around doors, window frames and skirting boards a 6mm fillet is recommended.  For external pointing of door and window frames the fillet face should be a minimum of 12mm across with a minimum depth of 6mm of sealant.

Prepare the joint by cleaning and priming if necessary.  Cut the nozzle to the desired angle and gun firmly into the joint to give a good solid fill.  Strike off the sealant flush with the joint sides within five minutes of application before skinning occurs.   A small amount of shrinkage will occur on curing.  If a flush finish is required fill the joint slightly proud of the surface to allow for shrinkage.

8.  USAGE

Tack free time 15 - 60 minutes dependent on thickness, temperature and humidity.

Full cure 3 - 5 days dependent on thickness, temperature and humidity.
