The process of grouting tile joints is an essential part of home decoration that cannot be overlooked. 

The grout not only needs to decorative effects but also practical value. 

Having a high-quality and aesthetically pleasing grout is a common pursuit for many homeowners.

 So, how should one choose out sealant? 

What kind of grout sealant can maintain its color for a long time?

 With these questions, let's compare two popular grout sealant currently: 

Polyurea grout sealant and Epoxy grout sealant. 

1. Different material components 

The main material of epoxy grout sealant is epoxy resin, which belongs to the epoxy material class of grout sealants. 

The raw material for Polyurea grout sealant is mainly polymeric acid ester polyurea, which is a high-tech new material.

 2. Different environmental friendliness

The raw materials for Epoxy grout sealant include curing agents and additives. Some low-quality products may contain phenols and amines, which are toxic.

 Polyurea grout sealant has simple components and is more environmentally friendly with lower VOC. 

It has a higher level of environmental friendliness. 

3. Different resistance yellowing

 Epoxy grout sealant is made of epoxy materials, which are not resistant to ultraviolet light. If used outdoors, it may oxidize turn yellow within a month or two. 

Polyurea grout sealant is inherently resistant to oxidation and ultraviolet light, making it highly resistant to yellowing.

It can be used both indoors and outdoors.

4. Different construction requirements

Epoxy grout sealant is easier to work with, allowing for a longer curing.

Once the construction process is familiar, one person can complete the grouting. 

The construction process for Polyurea grout sealant is similar to that epoxy grout sealant, but it is more challenging. 

The Polyurea material is highly adhesive and cures quickly, requiring two people to work together and a higher level of skill from the contractor.
