Commercial metal cladding refurbishment project

Independent cladding route comparison

Compare the specification—not just the coating company.

JWS Coatings UK, DriSilane, HD Sharman and Forti Nova approach commercial cladding refurbishment through different delivery models. This guide shows the questions procurement teams should ask before comparing price, warranty or programme duration.

Comparison basis: competitor information is summarised from public company and product pages reviewed in August 2026. Forti Nova is not affiliated with JWS Coatings UK, DriSilane or HD Sharman. Product specifications, guarantees and approvals can change; confirm the current project-specific position directly with each provider before procurement.

Four different commercial routes

What each public proposition actually leads with.

Contractor-led spray coating service

JWS Coatings UK

Public proposition

Its public website presents a nationwide on-site coatings contractor offering unit cladding, roof coatings, intumescent coatings, flooring and other spray-finishing services, supported by project examples and contractor credentials.

Potentially strong fit

Clients prioritising a contractor-led delivery route, broad on-site spraying capability and visible project portfolio.

Verify before award

The exact coating manufacturer, product build-up, cladding-specific warranty, substrate compatibility evidence, trial-area requirements and who owns manufacturer approval for the proposed specification.

Review source basis

Programme-led specification, product and applicator route

DriSilane

Public proposition

DriSilane describes a three-stage roofing and cladding refurbishment programme built around specification, product and specialist applicator selection. Its Steel Seal page describes a two-pack PU acrylic coating and states use on several factory-applied finishes, subject to its specification.

Potentially strong fit

Projects seeking a specialist, programme-led route focused on profiled metal roofing and cladding repair.

Verify before award

The exact project warranty, preparation standard, adhesion-testing protocol, film build, primer selection, QA records and whether the proposed build-up is specifically approved for the existing finish on the building.

Review source basis

Established manufacturer and approved-installer network

HD Sharman

Public proposition

Sharmans is strongly established in commercial roof and gutter refurbishment through Delcote, Seamsil and Plygene systems. Its public product page also lists Temadur 20 and Temadur 50 polyurethane paints for exterior metal and cladding applications.

Potentially strong fit

Projects where established roof, cut-edge or gutter systems, published guarantees and a recognised approved-installer network are central to procurement.

Verify before award

Which guarantee and certification apply to the cladding coating itself rather than to separate roof or gutter systems; the exact cladding preparation, primer, colour and warranty build-up for the project.

Review source basis

Technical specification, supply and approved-contractor coordination

Forti Nova + Prokol TopSpray35

Public proposition

Forti Nova positions TopSpray35 as a two-component aliphatic polyurethane protective topcoat within a survey-led cladding refurbishment programme. The route combines condition assessment, repair scope, substrate-specific preparation, direct manufacturer input, product supply and approved-contractor coordination.

Potentially strong fit

Commercial cladding projects needing a UV-stable RAL colour restoration route, transparent system boundaries and a qualifying manufacturer or complete-system warranty pathway.

Verify before award

Panel integrity, existing finish, adhesion, contamination, corrosion, primer, minimum film build, environmental conditions, application records and manufacturer acceptance before warranty eligibility is confirmed.

Tender comparison checklist

Make every bidder answer the same questions.

A low headline rate is meaningless when one proposal includes repairs, trial areas, masking, QA and manufacturer approval while another includes only cleaning and paint application.

Survey before quotation

Are panel condition, fixing lines, laps, sealants, cut edges and water-ingress routes mapped before the final scope is priced?

Repair scope separated

Does the proposal distinguish panel replacement, fixing renewal, corrosion treatment and sealant work from the coating stage?

Exact product and build-up

Are product chemistry, primer, preparation, coats, consumption and recoat conditions disclosed rather than hidden behind a generic system name?

Warranty scope evidenced

Is the warranty specifically applicable to this cladding build-up, substrate and applicator route, with conditions stated?

Like-for-like commercial comparison

Are access, masking, overspray controls, repairs, QA records, programme duration and exclusions included before prices are compared?

Occupied-building delivery

Does the delivery plan protect entrances, loading bays, HVAC intakes, vehicles, stock and neighbouring property while work proceeds?

Forti Nova counter-position

One technical route from survey to warranty records.

Forti Nova does not rely on a generic “spray and transform” claim. The commercial proposition is a documented refurbishment decision: confirm whether panels can be retained, define repairs, establish adhesion and primer requirements, then coordinate TopSpray35 supply and approved-contractor delivery.

Direct manufacturer input on qualifying specifications

TopSpray35 product and system boundaries stated clearly

25-year manufacturer warranty route on qualifying installations

Up to 35-year complete-system route where the approved build-up qualifies

RAL colour restoration with trial-area confirmation

Multiple coating technologies when TopSpray35 is not the right answer

Approved-contractor coordination rather than unsupported installation claims

Enquiry attribution and project records captured from first contact

Comparison FAQs

Straight answers before procurement.

Is Forti Nova an alternative to JWS Coatings UK for cladding refurbishment?

Yes, but the delivery models differ. JWS presents a contractor-led spray-coating service. Forti Nova provides technical specification, TopSpray35 supply and approved-contractor coordination. Compare the exact repair scope, preparation, coating build-up, QA, warranty and exclusions before deciding whether the proposals are genuinely equivalent.

Is TopSpray35 an alternative to DriSilane Steel Seal?

It may be a relevant alternative on suitable metal cladding projects, but it is not the same product or specification. The existing finish, adhesion, preparation, primer, film build, application conditions and warranty route must be compared project by project using current manufacturer information.

Is TopSpray35 an alternative to HD Sharman Temadur cladding coatings?

It may be considered as a different cladding-protection route where the substrate and existing finish are suitable. Procurement should compare the exact Temadur or TopSpray35 specification, primer, number of coats, consumption, preparation, QA records and cladding-specific warranty rather than relying on the wider reputation of either supplier's roof or gutter systems.

Which cladding coating route is best?

There is no defensible answer without the building survey, existing finish, panel condition, defect map, required colour, access constraints and warranty requirement. The correct route is the one that confirms those inputs before the coating specification is committed.

Is TopSpray35 the same as DriSilane Steel Seal or Temadur cladding paint?

No. These are different products and commercial routes. TopSpray35 is positioned by Forti Nova as a two-component aliphatic polyurethane protective topcoat within a confirmed system. DriSilane Steel Seal and the Temadur products should be assessed from their own current manufacturer documents and project specifications.

Can Forti Nova quote against JWS Coatings, DriSilane or HD Sharman specifications?

Forti Nova can review the project requirement and propose a technically appropriate TopSpray35 or alternative system route. A like-for-like comparison requires the competing preparation scope, primer, number of coats, consumption, repair scope, access, QA, warranty and exclusions—not only a headline price.

Does the longest headline warranty automatically mean the best specification?

No. Warranty value depends on what is actually covered, the approved build-up, exclusions, preparation obligations, inspection records, applicator status and manufacturer acceptance. A longer headline period does not repair an unsuitable substrate or incomplete preparation scope.
