Usage calculator for sealants and primers

For sealants

Please note: This values are approximate and serve as a rough guide for rightangled joints. The depth of the joints is measured to the rear of the profile. Depending on the processing method, additional expenditure of up to 25% is possible.


For primers

Please note: Primer consumption depends on the absorbency of the material of the adhesive edge and on the application method and can therefore only be stated approximately.

(valid for sealants with 25 % movement capability)

General valid joint dimension:

 

Schnittzeichnung Fugendimensionierung

The rule of thumb for calculating the joint dimension is as follows:
 

Sealant depth (t) = 0.5 x joint width (b).

The thickness of the sealant (d) equals 2/3 of the joint width(b).

 

 

 

 


The ratio between the width of the sealant in the joint (b) and the depth of the sealant in the joint (t) has to be as follows:

Joint width b in ratio of joint depth t (in mm) Source: Industrieverband Dichtstoffe e.V. / HS PR. Additional information to the IVD‘s information leaflets under www.ivd-ev.de
