AB  - The pressure near the deconfinement transition as determined up to now in lattice gauge theories shows unphysical behaviour:  it can become negative and may in SU (3) even have a gap at the transition.  This has been attributed to the use of only perturbatively known derivatives of coupling constants.  We propose a method to evaluate the pressure, which works without these derivatives, and is valid on large lattices.  In SU (2) we study the finite-volume effects and show that for lattices with spatial extent N-sigma greater-than-or-similar-to 15 these effects are negligible.  In SU (3) we then ontain a postive and continuous pressure.  The influence of non-perturbative corrections to the beta-function on the energy density are investigated and found to be important, in particular for the latent heat.
