Lets talk about different types of silicone sealant

Welcome to our How to Handyman series. This is the first in a series of videos about silicone and how to remove and how to apply it. In this first video we talk about the different types of silicone. Quick Reference: Low Modulus Acetoxy (LMA) sealants are the cost-effective "all-rounders", they are suitable for a wide variety of general building, sanitary (when they contain a fungicide), glazing interior and exterior applications and adhere to many common building materials. Low Modulus Neutral (LMN) sealants are the best option for the sealing of UPVC Window or Door Frames (exterior). They offer better adhesion, accommodate more movement and are generally longer lasting than LMA's. High Modulus Acetoxy (HMA) sealants are most commonly used for kitchen and sanitary applications (ensure the sealant contains a fungicide). Neutral Cure Silicone: most silicone sealants release acetic acid while curing. This gives off a characteristic vinegar-like smell. In some circumstances, this odour may be undesirable, or the acetic acid may have a negative impact on the materials being sealed (for example some clear polycarbonate materials may suffer slight staining when exposed to acetic acid). Neutral cure silicone products reduce or eliminate the production of acetic acid while curing. Often the better quality sealants also tend to be neutral cure products.
