Overview

Wekano H2720 is a high-performance elastomeric joint sealant designed for expansion joints in concrete surfaces and structures. It absorbs structural movement from thermal expansion and contraction without cracking or losing cohesion, providing long-term protection against water and dust ingress.

It is an ideal engineered solution for filling gaps between roof tiles and joints between walls and concrete, forming a flexible rubber seal that prevents structural damage and extends the life of the waterproofing system.

Application Guide

01

Clean the joint

The joint must be completely clean and dry. Remove dust, oil, cement residue or loose material with compressed air or a brush.
02

Mask the edges (optional)

For a neat finish, apply masking tape along both sides of the joint to protect the tiles.
03

Gun application

Place the sausage in the sealant gun, cut the nozzle to suit the joint width and fill the joint evenly without air bubbles.
04

Tooling

Immediately smooth the sealant with a spatula or tool dipped in soapy water, then remove the masking tape.
