Why Surface And Product Composition Matter
Matching the correct sealant with the correct surface allows you to do your job right the first time around. The elasticity, longevity and drying times of sealants depend on the solid and liquid ingredients — the product composition — used in the sealant. While there’s no “one size fits all” product, Mulco® has created different products with unique compositions for just about every project you encounter.
Certain products react unfavorably to particular surfaces because they are meant for other surfaces. You will want to check the Mulco Sealant Selection Chart and Mulco Sealant Characteristics Chart before applying the sealant.
There are three types of sealants:
-
water-based
-
solvent-based
-
chemical-based

Quality and Effectiveness
Mulco® manufactures high-performance sealants for a wide range of budgets. While all sealants adhere to Mulco’s high standards, there are plenty of economical options to help you stay within your resources.
The effectiveness level of each sealant is rated between 1 and 5 in the Mulco Sealant Selection Chart, depending on the surface to which it is applied.
If several products are suitable for your job, check the Mulco Sealant Characteristic Chart to narrow your choices.
