Titebond sealants: questions and answers

Frequently asked questions about Titebond sealants

1. Which Titebond sealants are suitable for interior and exterior use?

Almost all Titebond sealants in our range are suitable for both interior and exterior use, although their properties differ according to the application. „Titebond WeatherMaster Sealant“ is a versatile polymer sealant, ideal for sealing windows, doors, cladding and vents thanks to its strong adhesion to wood, masonry, PVC and other building materials. „Titebond WeatherMaster Metal Roof Sealant“ is designed specifically for metal roofs and resists extreme weather. „Titebond Pro-Grade Plus“ and “Titebond Pro-Grade” are professional siliconised acrylic and acrylic sealants suitable for construction and repair work, especially where painting is required. „Titebond 100% Silicone Sealant“is commonly used indoors and outdoors, for example around windows, in kitchens, bathrooms and shower enclosures, or on timber trim, thanks to its moisture resistance and attractive finish. It is the only one approved by the FDA for food contact and can withstand extreme temperatures.

Tip: For exterior work requiring resistance to UV and temperature changes, choose „WeatherMaster Sealant“ or „WeatherMaster Metal Roof Sealant“. For bathrooms, shower enclosures and kitchens, its excellent resistance to water and mould and FDA approval for food contact make the choice “100% Silicone Sealant”. „Pro-Grade“ acrylic sealant is ideal for painted or timber trim in drier conditions.

2. What is the difference between Titebond WeatherMaster Sealant, Titebond WeatherMaster Metal Roof Sealant and Titebond Pro-Grade Plus?

„Titebond WeatherMaster Sealant“ is a versatile polymer sealant for various surfaces, including wood, masonry, PVC and cladding, with a tensile strength of around 400 PSI (approximately 28.1 kg/cm²). „Titebond WeatherMaster Metal Roof Sealant“ is designed specifically for metal roofs, offering greater flexibility, accommodating up to 50% joint movement, and resistance to heavy rain, wind and UV, with a strength of around 350 PSI (approximately 24.6 kg/cm²). „Titebond Pro-Grade Plus“ is a silicone-enhanced acrylic sealant for professional construction work, including paintable joints, with a strength of around 300 PSI (approximately 21.1 kg/cm²). It is less flexible, accommodating approximately 25% joint movement, but is easy to tool and suitable for interior and exterior finishing.

Tip: Choose „WeatherMaster Sealant“ for general building work, „WeatherMaster Metal Roof Sealant“ for metal roofs, downpipes and window sills, and „Pro-Grade Plus“ for various joints, including plasterboard, timber trim and skirting boards.

3. Are Titebond sealants resistant to moisture and mould?

All Titebond sealants resist moisture, but mould resistance varies. „Titebond 100% Silicone Sealant“ contains fungicides that protect against mould, making it ideal for damp rooms such as bathrooms and kitchens. „Titebond WeatherMaster Sealant“ and „Titebond WeatherMaster Metal Roof Sealant“resist moisture and water, making them suitable for outdoor use, but they are not specifically formulated for mould prevention. „Titebond Pro-Grade Plus“ resists moisture, but the risk of mould may be greater in damp rooms because it is intended primarily for finishing work.

Tip: For bathrooms, choose „100% Silicone Sealant“. For outdoor structures exposed to rain and wind, use „WeatherMaster Sealant“ or „WeatherMaster Metal Roof Sealant“. „Pro-Grade Plus“ is suitable for moderately humid environments.

4. What advantages do Titebond sealants offer over other manufacturers' products?

Titebond sealants use advanced polymer technology for better adhesion, flexibility and durability than traditional silicone, acrylic or polyurethane sealants. According to Titebond's website, „Titebond WeatherMaster Sealant“ outperforms competitors through strong, adhesive-like bonding to a variety of surfaces and resistance to UV, water and temperatures from –59°C to +100°C. It can even be used on damp surfaces. The acrylic sealant „Titebond Pro-Grade“stands out for its durability, resistance to yellowing, ease of use and paintability, while „100% Silicone Sealant“ offers mould prevention and water resistance. All Titebond sealants are non-toxic and free from oxime solvents, making them safer.

Benefits:
- Strong adhesion: Suitable for wood, masonry, metal, PVC and stone.
- Flexibility: Accommodates up to 50% joint movement, except Prograde Plus at approximately 25%.
- Resistance: UV, moisture and temperature changes.
- Safety: No toxic solvents.

Tip: Choose „WeatherMaster Sealant“ for general applications, „Pro-Grade“ for paintable joints, „100% Silicone Sealant“ for damp rooms.

5. Can Titebond sealants be painted?

Most Titebond sealants, except „Titebond 100 % Silicone Sealant“, can be painted with water-based or acrylic paints. „Titebond WeatherMaster Sealant“ and „Titebond Pro-Grade“ are easy to paint. „Titebond 100% Silicone Sealant“ cannot be painted.

Tip: For paintable joints, choose the acrylic sealant „Pro-Grade“ or the polymer sealant „WeatherMaster Sealant“. „Pro-Grade Plus“ is suitable for finishing work requiring a colour match. „100% Silicone Sealant“ should be used where painting is not required.

6. How strong are Titebond sealants?

Titebond sealant strength varies: „Titebond WeatherMaster Sealant“– approximately 400 PSI (approximately 28.1 kg/cm²), „Titebond WeatherMaster Metal Roof Sealant“– approximately 350 PSI (approximately 24.6 kg/cm²), „Titebond Ultimate MP Sealant“ – approximately 380 PSI (approximately 26.7 kg/cm²), „Titebond Prograde Plus“– approximately 300 PSI (approximately 21.1 kg/cm²), and „Titebond 100% Silicone Sealant“ – approximately 250–300 PSI (approximately 17.6–21.1 kg/cm²).

Tip: For maximum strength, choose „WeatherMaster Sealant“. For metal roofs or damp and extreme weather conditions, choose „WeatherMaster Metal Roof Sealant“. „Pro-Grade Plus“ and „Pro-Grade“ is suitable for lighter-duty applications.

7. How should Titebond sealants be applied?

Surfaces must be clean, dry and free from dust or old sealant, except for Titebond moisture-curing polymer sealants. Apply with a sealant gun and tool the joint with a spatula within 10–15 minutes. „WeatherMaster Sealant“, „WeatherMaster Metal Roof Sealant“ cures in 24–48 hours at 50–60% humidity and 10–30°C. „100% Silicone Sealant“ cures at around 1–2 mm per day, „Pro-Grade“ in 24–72 hours.

Tip: Use masking tape for clean lines. In damp rooms, choose „100% Silicone Sealant“ and provide ventilation. „WeatherMaster Sealant“ is suitable for urgent work on damp surfaces, „Pro-Grade“ for paintable joints.
